Ispol'zovanie rentgenovsokgo fona dlya predskazaniya IK izlucheniya AYaG (Does the AGN Unified Model Evolve with Redshift? Utilizing the X-ray Background to Predict the Mid-Infrared Emission of AGN) Authors: D.R. Ballantyne et al. Comments: 27 pages, 17 figures (12 in color), accepted by the ApJ Rentgenovskii fon sozdaetsya v osnovnom vnegalakticheskimi istochnikami - aktivnymi yadrami galaktik (AYaG). Eti ob'ekty aktivno izuchayutsya metodom populyacionnogo sinteza. V osnove lezhit t.n. edinaya model', v kotoroi raznica mezhdu raznymi AYaG ob'yasnyaetsya v osnovnom massoi chernoi dyry. A dlya opisaniya razlichnyh nablyudatel'nyh proyavlenii ispol'zuyutsya effekty orientacii: smotrim li my perpendikulyarno pogloshayushemu toru vokrug chernoi dyry, ili zhe luch zreniya lezhit vblizi ploskosti tora i t.p. V standartnoi edinoi modeli v nulevom priblizhenii schitaetsya, chto parametry AYaG ne evolyucioniruyut so vremenem. Odnako yasno, chto evolyuciya dolzhna byt', i v modifikaciyah modeli ee kak-to pytayutsya uchityvat'. V svoei stat'e avtory delayut sleduyushee. Oni ispol'zuyu dannye populyacionnogo modelirovaniya rentgenovskogo fona dlya predskazaniya svetimostei v infrakrasnom diapazone. Zatem rezul'taty sravnivayutsya s dannymi, poluchennymi na Spitcere. Avtory polagayut, chto imenno sravnenie raschetov s dannymi Spitcera pozvolit nalozhit' sushestvennye ogranicheniya na modeli evolyucii torov vokrug chernyh dyr v AYaG. astro-ph/0609005 Evolyuciya tempa zvezdoobrazovaniya ot z=5 do z=0 po dannym glubokogo obzora VIMOS VLT (The cosmic star formation rate evolution from z=5 to z=0 from the VIMOS VLT Deep Survey) Authors: L. Tresse et al. Comments: Submited to A&A, 20 pages, 12 figures Po dannym o pochti 12 000 spektrah galaktik avtory vosstanavlivayut povedenie tempa zvezdoobrazovaniya dlya epohi ot krasnogo smesheniya 5 do nashego vremeni. Avtory vydelyayut neskol'ko epoh s raznoi evolyuciei tempa zvezdoobrazovaniem (otmechu, chto rech' idet o nablyudeniyah na dvuh ploshadkah v dvuh napravleniyah). Pokazano izmenenie tempa zvezdoobrazovaniya so vremenem. Novye dannye, opisannye v stat'e pokazany krasnymi kruzhkami. astro-ph/0609045 Deficit ugleroda na vneshne zagryaznennyh belyh kardikah: ukazaniya na akkreciyu asteroidov (Carbon Deficiency in Externally-Polluted White Dwarfs: Evidence for Accretion of Asteroids) Authors: M. Jura Comments: 23 pages, 6 figures, accepted for ApJ Interesnaya ideya. Okazyvaetsya, est' belye karliki, ch'i spektry govoryat o tom, chto na ih poverhnost' vypadalo kakoe-to vneshnee veshestvo, poetomu ih nazyvayut vneshne zagryaznennymi (externaly polluted). Obychno, eto veshestvo mezhzvezdnoi sredy. Odnako okazyvaetsya, chto sredi vneshne zagryaznennyh est' belye karliki s deficitom ugleroda. Takoe nedostatok ugleroda nel'zya ob'yasnit' akkreciei iz mezhzvezdnoi sredy. Avtor polagaet, chto belye karliki akkrecirovali asteroidy! astro-ph/0609125 O zakone tyagoteniya, masse neitrino i dokazatel'stve sushestvovaniya temnoi materii (On the Law of Gravity, the Mass of Neutrinos and the Proof of Dark Matter) Authors: Garry W. Angus et al. Comments: 5 pages, 1 figure Avtory anliziruyut dannye po stalkivayushimsya skopleniyam v ramkah standartnoi OTO i MOND. Pokazano, chto temnaya materiya neobhodima. No takoi zhe vyvod mozhno sdelat' i po drugim dannym o skopleniyah, a takzhe po dannym o reliktovom izluchenii. Minimal'nym kompromissom dlya priemlemosti MOND yavlaetsya dobavlenie neitrino s massoi poryadka 2 eV. T.e. narod pytaetsya ob'yasnit' dannye bez "ekzoticheskoi temnoi materii" (neitralino i t.p.), no v ramkah MOND. O perspektivah pryamogo poiska chastic temnoi materii v laboratoriyah i ob ih svyazi s budushimi ukoritel'nymi eksperimentami mozhno pochitat' zdes': astro-ph/0609126. obzor astro-ph/0609142 Svyaz' mezhdu sverhnovymi i gamma-vspleskami (The Supernova -- Gamma-Ray Burst Connection) Authors: S. E. Woosley, J. S. Bloom Comments: Published in the Annual Reviews of Astronomy and Astrophysics (Sept 2006). 54 pages, 11 figures (this is the pre-copyedited version, submitted 22 Feb 2006; published online as a Review in Advance on 16 June 2006) V sovremennoi nauke o gamma-vspleskah dostatochno standartnoi yavlyaetsya gipoteza o svyazi gamma-vspleskov so sverhnovymi. Gipoteza eta imeet nekotoruyu nablyudatel'nuyu podderzhku, odnako est' u nee i trudnosti. Vo-pervyh, yasno, chto ne vse gamma-vspleski (i dazhe ne vse dlinnye) svyazany so sverhnovymi. Vo-vtoryh, neponyatno, verno li my otozhdestvlyaem nablyudaemye v optike fenomeny kak "sverhnovye". Podrobnee obo vsem eto mozhno prochest' v obzore. miniobzor astro-ph/0609149 Rezul'taty po galakticheskim istochnikam po dannym pervogo cikla raboty MAGIC (Results from MAGIC's first observation cycle on galactic sources) Authors: Javier Rico (for the MAGIC Collaboration) Comments: 6 pages, 8 figures. Prepared for "The Multi-messenger Approach to High-energy Gamma-ray Sources", Barcelona (Spain) 4-7 July 2006 Kratkoe izlozhenie rezul'tatov pervogo cikla nablyudenii na nazemnom gamma-teleskope MAGIC. Rezul'taty po vnegalakticheskim istochnikam summirovany v sleduyushei stat'e astro-ph/0609152. miniobzor astro-ph/0609161 Astronomiya s malymi teleskopami (Astronomy with Small Telescopes) Authors: Bohdan Paczynski Comments: 11 pages, submitted to PASP V stat'e rassmatrivayutsya proekty, osushestvlyaemye na instrumentah s apperturoi ot 7 (semi!) santimetrov. Privodyatsya ssylki na veb-stranicy proektov, opisyvayutsya ih osnovnye rezul'taty. Razumeetsya, rassmotreny i proekty budushih instrumentov. V osnovnom eto vse avtomaticheskie teleskopy i ih sistemy, prednaznachennye dlya obzorov neba. miniobzor astro-ph/0609207 Astronomiya s lazernoi iskusstvennoi zvezdoi dlya adaptivnoi optiki: korotkii obzor, tekushee sostoyanie i yarkoe budushee (Astronomical Science with Laser Guide Star Adaptive Optics: A Brief Review, a Current Snapshot, and a Bright Future) Authors: Michael C. Liu Comments: 11 pages, Proceedings of the SPIE Vol. 6272, "Astronomical Telescopes and Instrumentation (Orlando, FL): Advances in Adaptive Optics II" (May 2006) Daetsya obzor po teleskopam, ch'e vysokoe kachestvo raboty obespechivaetsya adaptivnoi optikoi s ispol'zovaniem lazernoi iskusstvennoi zvezdy. Takaya metodika ispol'zuetsya, v chastnosti, na teleskope Kek-II (est' eshe tri bolee melkih instrumenta, gde takzhe primenyaetsya lazernaya iskusstvennaya zvezda dlya polucheniya izobrazhenii difrakcionnogo kachestva). Avtory privodyat obshirnuyu bibliografiyu. Stat'ya budet interesna vsem, kto interesuetsya sovremennymi metodami nablyudenii. obzor astro-ph/0609208 Sverhnovye s obrazovaniem par: teoriya i nablyudeniya (Pair-Production Supernovae: Theory and Observation) Authors: Evan Scannapieco Comments: 20 pages, 8 figures, presented at the 2006 STScI May Symposium, Massive Stars: From Pop III and GRBs to the Milky Way Davlenie v nedrah ochen' massivnyh zvezd obespechivaetsya davleniem izlucheniya. Chem vyshe massa zvezdy, tem vyshe temperatura v centre. V yadrah svetil s massoi okolo 200 solnechnyh mogut vozniknut' usloviya, kogda fotony nachnut rozhdat' elektron-pizotronnye pary. Eto privedet k umen'sheniyu davleniya. Nachnetsya kollaps. Imenno tak i ustroeny sverhnovye s rozhdeniem par. Stol' massivnye zvezdy ne obrazuyutsya v nashe vremya, kogda metallichnost' mezhzvezdnogo gaza vysoka. Oni mogli poyavlyat'sya tol'ko v dostatochno molodoi Vselennoi. Kraine interesno ponyat', proishodili li togda vzryvy za schet rozhdeniya par. Avtory dayut obzor po sverhnovyh s rozhdeniem par, i rassmatrivayut vopros ob ih detektiruemosti na planiruemom JWST (t.e. na Vebbovskom kosmicheskom teleskope). gr-qc/0609024 Nablyudeniya rozhdayushihsya chernyh dyr i problema poteri informacii (Observation of Incipient Black Holes and the Information Loss Problem) Authors: Tanmay Vachaspati, Dejan Stojkovic, Lawrence M. Krauss Comments: 13 pages; 8 figures Propustil by stat'yu, esli by ne prof. Postnov. (Proizoshedshee lishnii raz dokazyvaet, chto ochen' polezno po utram obsuzhdat' svezhie stat'i v Arhive i t.p. K sozhaleniyu, massovogo haraktera takie diskussii u nas ne nosyat). Avtory issledovali kollaps sfericheskoi obolochki (domennoi stenki) v kvantovoi modeli. Tak zhe kak i v klassicheskom sluchae, dlya udalennogo nablyudatelya kollaps dlitsya vechno. Tut vse horosho. Interesnoe dal'she. U avtorov poluchaetsya, chto obrazovaniya gorizonta taki ne proishodit. Vse uspevaet isparit'sya do ego poyavleniya. T.o., net problem s poterei informacii (informacionnyi paradoks, svyazannyi s chernymi dyrami, yavlyaetsya predmetom burnogo obsuzhdeniya). Stat'ya dostatochno tehnicheskaya. Bylo by horosho, esli by kto-to iz specialistov v dannoi konkretnoi oblasti vystupil s raz'yasnenniyami i poyasnenniyami. V chastnosti, bylo by vazhno ponyat' naskol'ko rezul'tat model'no zavisim, naskol'ko mogut byt' kritichny sdelannye predpolozheniya i t.p. miniobzor gr-qc/0609028 Korotkii obzor istochnikov i zadach dlya LISA (A brief survey of LISA sources and science) Authors: Scott A. Hughes Comments: 8 pages, 2 figures, for the Proceedings of the Sixth International LISA Symposium LISA - eto kosmicheskii proekt, prednaznachennyi dlya detektirovaniya gravitacionnyh voln. Izyuminka sostoit v tom, chto instrument smozhet rabotat' na dostatochno nizkih chatsotah. Odnimi iz osnovnyh istochnikov v etom diapazone yavlyayutsya massivnye dvoinye s chernymi dyrami. V stat'e daetsya obzor osnovnyh zadach, stoyashih pered LISA, a takzhe opisyvayutsya ozhidaemye rezul'taty. astro-ph/0609335 TrES-2: pervaya tranzitnaya planeta v keplerovskom pole (TrES-2: The First Transiting Planet in the Kepler Field) Authors: Francis T. O'Donovan, et al. Comments: Accepted for publication in ApJL. 15 pages, 2 figures Otkryta vtoraya tranzitnaya planeta v ramkah proekta TrES (Trans-atlantic Exoplanet Survey). Materinskaya zvezda ochen' pohozha na Solnce. A planeta pohozha na Yupiter, vot tol'ko period obrasheniya slishkom korotkii - dva s polovinoi dnya. Sushestvenno, chto planeta budet nablyudat'sya kosmicheskim proektom Kepler. Za 4 goda raboty sputnik uvidit okolo 600 prohozhdenii planety po disku zvezdy, chto pozvolit poluchit' tochnye dannye i po zvezde, i po planete. astro-ph/0609369 HAT-P-1b: ekzoplaneta s bol'shim radiusom i maloi plotnost'yu, prohodyashaya po disku chlena dvoinoi sistemy (HAT-P-1b: A Large-Radius, Low-Density Exoplanet Transiting one Member of a Stellar Binary) Authors: G. A. Bakos et al. Comments: pages, submitted to ApJL V ramkah proekta HATNet obnaruzhena lyubopytnaya planeta. S odnoi storony, eto vrode obychnyi "goryachii yupiter". S drugoi .... Vo-pervyh, planeta obrashaetsya vokrug komponenta dvoinoi sistemy. Vo-vtoryh, otkryta ona po dannym o prohozhdenii po disku zvezdy. A eto pozvolyaet opredelit' parametry planety. Otsyuda vytekaet interesnoe "v-tret'ih". Planeta imeet massu v dva raza men'she, chem u Yupitera, a razmer v poltora raza bol'she, eto privodit k samoi nizkoi plotnosti sredi vseh izvestnyh planet (razumeetsya, tut vazhno to, chto blizost' zvezdy razogrevaet atmsoferu planety, chto privodit k ee rasshireniyu, tak chto nado byt' ostorozhnym v vostorgah). Naklonenie orbity sostavlyaet pochti 90 gradusov! obzor astro-ph/0609389 Fizika zvezdnyh koron (Physics of Stellar Coronae) Authors: M. Guedel Comments: 1 pages, 42 figures, svmult style. To be published in Lecture Notes from summer school on "Turbulence and Fine Scale Structure in Solar and Astrophysical Plasmas" Lekcii po fizike zvezdnyh koron. Kak pishet avtor, eto vzglyad astronoma-zvezdnika na problemu. T.e., v lekciyah net slozhnyh teoreticheskih vykladok ili detal'nogo opisaniya fiziki. Tekst posvyashen v osnovnom dannym nablyudenii i ih interpretacii. astro-ph/0609393 Galaktika na krasnom smeshenii 6.96 (A galaxy at a redshift z = 6.96) Authors: Masanori Iye, et al. Comments: 10 pages, 3 figure, 1 table, Nature, Vol. 443, 186-188 (2006) Obnaruzhena ocherednaya dalekaya galaktika. Novost' uzhe proshla po lentam SMI. Zdes' zhe zhelayushie mogut naiti detali. miniobzor astro-ph/0609397 Zavtrashnii den' opticheskoi interferometrii (Tomorrow optical interferometry: astrophysical prospects and instrumental issues) Authors: F. Malbet Comments: 8 pages, invited review at the "Visions in IR astronomy" conference held in Paris, 21-23 March 2006 V poslednie gody aktivno razvivaetsya opticheskaya interferometriya (VLTI, Keck, etc.). Yasno, chto v budushem nas zhdut novye proekty, osnovannye na novyh tehnicheskih razrabotkah. Etomu obzor i posvyashen. astro-ph/0609403 Nablyudeniya zavala GZK v eksperimente HiRes (Observation of the GZK Cutoff by the HiRes Experiment) Authors: G.B. Thomson, for the High Resolution Fly's Eye (HiRes) Collaboration Comments: 15 pages, 5 figures, submitted to Proceedings of the Quarks'06 Conference Kak izvestno, v spektre kosmicheskih luchei na ochen' vysokih energiyah Greizenom, Zacepinym i Kuz'minym (GZK) okolo 40 let nazad byl predskazan zaval, svyazannyi s vzaimodeistviem chastic s reliktovym fonom. Neskol'ko let nazad eksperimentatory dobralis' do etoi oblasti spektra. Chastic s vysokimi energiyami malo (chto-to v duhe odnoi chasticy na kvadratnyi kilometr raz v god). Poetomu stroyatsya gigantskie ustanovki, sposobnye poluchat' dannye o potoke chastic na bol'shoi ploshadi. Est' raznye metodiki nablyudeniya takih chastic, raznye sposoby ocenki ih energii. V techenii ryada let shel spor o tom, nablyudaetsya li zaval ili net. V amerikanskom eksperimente HiRes uchenym udalos' uvidet' zaval. Etot rezul'tat i opisan v stat'e. Rezul'taty yaponskogo eksperimenta (Agasa) neskol'ko protivorechivy. Na protyazhenii rada let ego avtory zayavlyali ob otsutstvii zavala. No v poslednee vremya posle pereobrabotki dannym s pomosh'yu novogo programmnogo obespecheniya (paket CORSIKA) byl poluchen rezul'tat, sovmestimyi s dannymi HiRes. Znachimost' rezul'tatov ne slishkom vysokaya, poetomu pridetsya zhdat' rezul'tatov eksperimenta Ozhe. astro-ph/0609416 Obrazovanie dvoinogo pul'sara PSR J0737-3039A/B (The Formation of the Double Pulsar PSR J0737-3039A/B) Authors: I. H. Stairs, et al. Comments: To appear in MNRAS Letters Otkrytie dvoinogo radiopul'sara stalo vazhnym rezul'tatov dlya ryada napravlenii. 1. Nalichie takogo ob'ekta pozvolyaet issledovat' vazhnye effekty, imeyushie mesto v pul'sarnyh magnitosferah (napomnyu, chto okonchatel'noi teorii magnitosfer pul'sarov tak i net). 2. Obnaruzhenie takogo ob'ekta pozvolilo povysit' "nablyudatel'nyi" predel na kolichestvo sliyavayushihsya dvoinyh neitronnyh zvezd, chto vazhno dlya ocenki effektivnosti raboty detektorov gravitacionnyh voln. Krome togo, ocenka tempa sliyanii po nablyudaemym sistemam, sostoyashim iz dvuh neitronnyh zvezd, nakonec-to stala sovpadat' s raschetami metodom populyacionnogo sinteza. 3. Dvoinoi radiopul'sar otkryvaet novye vozmozhnosti dlya proverki Obshei teorii otnositel'nosti (sm. ssylku nizhe). 4.Nalichie takogo ob'ekta brosaet vyzov teoriyam evolyucii zvezd. Poslednemu punktu i posvyashena stat'ya. Delo v tom, chto: 1. U pul'sara nizkaya prostranstvennaya skorost'. T.e., ne bylo bol'shogo kika (bol'shogo dopolnitel'nogo impul'sa pri vzryve sverhnovoi) 2. U sistemy nizkii, no nenulevoi, ekscentrisitet orbity. 3. Sistema imeet dovol'no korotkii orbital'nyi period. Vse vmeste eto stavit problemy v postroenii evolyucionnogo scenariya, privedshego k poyavleniyu takoi sistemy. Odin iz vazhnyh vyvodov sostoit v tom, chto predsverhnovaya, porodivshaya bolee molodoi pul'sar (pul'sar V), imela nizkuyu massu, okolo 2 mass Solnca ili dazhe men'she. T.o. vryad li eto byla obychnaya sverhnovaya s kollapsom zheleznogo yadra. S drugoi storony, pohozhaya dvoinaya sistema PSR B1534+12 po vsei vidimosti imela nekol'ko inuyu istoriyu. T.o., vozmozhny raznye evolyucionnye puti, chto nado uchityvat' v modelyah, opisyvayushih poyavlenie takih sistem. Sm. takzhe stat'yu astro-ph/0609417 toi zhe gruppy avtorov, v kotoroi rassmatrivayutsya testy OTO po dannym o dvoinom pul'sare. My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing). physics/0609047 Lyudvig Bol'cman (Ludwig Edward Boltzmann) Authors: S.Rajasekar, N.Athavan Comments: 14 pages, 1 figure Biografiya Lyudviga Bol'cmana i kratkoe opisanie ego osnovnyh rabot. physics/0609116 K voprosu o dinamike h-indeksa v slozhnyh setyah s sosushestvuyushimi soobshestvami (On the Dynamics of the $h-$index in Complex Networks with Coexisting Communities) Authors: Luciano da Fontoura Costa Comments: 9 pages, 1 table, 2 figures. Prodolzhayutsya popytki modificirovat' indeks Hirsha (h-indeks). Avtor modeliruet situaciyu s dvumya soobshestvami uchenyh. Po rezul'tatam modelirovaniya on pytaetsya predlozhit' modifikaciyu indeksa. Moe lichnoe mnenie sostoit v tom, chto: 1. Takie popytki v principe nado delat' 2. Luchshe ne prosto modificirovat', a pytat'sya predlozhit' kakuyu-to al'ternativu 3. Poskol'ku vse ponimayut, chto vse eti indeksy dostatochno uslovny, to preimushestvo budet za prostymi model'no nezavisimymi indeksami. Vazhno tol'ko, chtoby oni obladali vzaimodopolnitel'nymi nedostatkami. Togda ispol'zovanie nebol'shogo chisla neskol'kih prostyh indeksov pozvolit prinyat' adekvatnoe reshenie, opirayas' na neskol'ko yasnyh formal'nyh kriteriev. Vernut'sya k nachalu stranicy
