Referaty otdel'nyh statei obzor astro-ph/0504435 Galakticheskie vetra (Galactic Winds) Authors: S. Veilleux et al. Comments: 53 pages, 6 figures in jpg format, to be published in 2005 Annual Review of Astronomy & Astrophysics Galakticheskie vetra - eto krupnomasshtabnye dvizheniya gaza v galaktikah. Svyazany oni v osnovnom so zvezdoobrazovaniem: so sverhnovymi ili moshnym zvezdnym vetrom. Chast' vetrov mozhet takzhe porozhdat'sya aktivnost'yu galakticheskih yader. Yarkim primerom galaktiki s moshnymi vetrami yavlyaetsya M82 - t.n. "vzryvayushayasya galaktika". Na samom dele, nikakogo edinichnogo vzryva net, a est' prosto ochen' vysokii temp formirovaniya zvezd. V poslednie gody stalo vozmozhnym nablyudat' s horoshim razresheniem galaktiki na bol'shih krasnyh smesheniyah. Tam v srednem temp zvezdoobrazovaniya vyshe - sootvetstvenno, sil'nee vetra. Vetra vazhny ne tol'ko sami po sebe, no i kak mehanizm peremeshivaniya himicheskih elementov vnutri galaktik, a takzhe kak mehanizm vybrosa elementov v mezhgalakticheskuyu sredu. Tema eta ne samaya obsuzhdaemaya v populyarnoi literature, tak chto horoshii ponyatnyi obzor budet kak nel'zya k stati. astro-ph/0504452 Aktivnost' gigantskih vspyshek magnitarov na ochen' bol'shih energiyah (Ultrahigh Energy Activity in Giant Magnetar Outbursts) Authors: David Eichler Comments: 11 pages Tradicionno obychnye kosmicheskie gamma-vspleski rassmatrivayutsya kak vozmozhnye istochniki razlichnyh tipov chastic vysokih energii. Odnako vspyshka magnitara, proizoshedshaya 27 dekabrya, okazalas' sushestvenno yarche izvestnyh gamma-vspleskov (yarche s tochki zreniya zemnogo nablyudatelya, ee sobstvennoe energovydelenie, konechno zhe, ustupaet obychnym gamma-vspleskam). V svyazi s etim avtor rassmatrivaet gigantskie vspyshki magnitarov kak vozmozhnye istochniki kosmicheskih luchei sverhvysokih energii. Otmetim, chto vyskazyvalis' mneniya o tom, chto kosmicheskie luchi sverhvysokih energii korreliruyut s ul'tramoshnymi IK galaktikami (sm., naprimer dve raboty Marii Giller i ee soavtorov astro-ph/0308532; astro-ph/0203337. Odnako vyvody o korrelyacii osparivalis', sm. astro-ph/0410741). V nashei stat'e s Borisom Shternom my obsuzhdali vozmozhnuyu svyaz' magnitarov s takimi galaktikami (sm. takzhe astro-ph/0502391). V nih chislo magnitarov dolzhno byt' bol'she. Ocenki pokazyvayut, chto temp gigantskih vspyshek mozhet sostavlyat' bolee odnoi vspyshki v god! Znachit, tam vyshe i veroyatnost' vstretit' molodoi magnitar. Takie istochniki mogut davat' ili bolee moshnye vspyshki (iz-za bOl'shego magnitnogo polya i men'shih periodov vrasheniya), ili zhe prosto vspyshki mogut idti chashe (tak, naprimer, glitchi radiopul'sarov chashe proishodyat u molodyh neitronnyh zvezd, gigantskie vspyshki mogut byt' svyazany s glitchami, t.o. estestvenno predpolozhit' rost ih chisla s umen'sheniem vozrasta neitronnoi zvezdy). V svete stat'i Davida Eihlera svyaz' kosmicheskih luchei sverhvysokih energii i galaktik s moshnym zvezdoobrazovaniem mozhet probresti novyi ottenok, svyazannyi s bOl'shim kolichestvom magnitarov (v tom chisle molodyh) v etih galaktikah. miniobzor astro-ph/0504454 Magnitnye polya v zvezdnoi materii vysokoi plotnosti (Magnetic Fields in High-Density Stellar Matter) Authors: German Lugones Comments: Invited review, conference "Magnetic Fields in the Universe: from Laboratory and Stars to Primordial Structures", Angra dos Reis, Brazil, Nov 28 - Dec 3, 2004, eds.

Jenet, George B. Hobbs, K.J. Lee, Richard N. Manchester Comments: 8 pages, Accepted by ApJ Letters Kak izvestno, radiopul'sary mozhno ispol'zovat' v kachestve nezavisimyh standartov tochnogo vremeni. Krome togo, ih mozhno ispol'zovat' i kak nezavisimye detektory gravitacionnyh voln! Ideya eta ne novaya (ee obsuzhdali i v SSSR, naprimer Mihail Vasil'evich Sazhin, na nego avtory akkuratno ssylayutsya). Tem ne menee, seichas perspektiva registracii fona gravitacionnyh voln vyglyadit gorazdo realistichnee chem 30 let nazad. astro-ph/0504479 Ogranicheniya na modeli populyacionnogo sinteza po populyacii dvoinyh neitronnyh zvezd (Constraining population synthesis models via the binary neutron star population) Authors: R. O'Shaughnessy et al. Comments: Submitted to ApJ. Uses emulateapj.cls. 8 pages + 7 figures Kak izvestno, sliyaniya dvuh neitronnyh zvezd rassmatrivayutsya kak naibolee veroyatnye istochniki gravitacionnyh voln, kotorye smogut registrirovat' detektory tipa LIGO i VIRGO. Menee izvestno, chto raschety metodom populyacionnogo sinteza pokazyvayut, chto sliyaniya neitronnyh zvezd s chernymi dyrami mogut okazat'sya bolee veroyatnymi istochnikami (takim raschety provodilis', naprimer, v otdele Relyativistskoi astrofiziki GAISh pod rukovodstvom V.M. Lipunova). Odnako velika neopredelennost' v raschetah. Avtory predalagayut ispol'zovat' dannye po izvestnym sistemam, sostoyashim iz dvuh neitronnyh zvezd, dlya umen'sheniya etoi neopredelennosti. Eto lish' pervaya rabota avtorov v dannom napravlenii, tak chto "mnogoe sdelano, no mnogoe eshe predstoit". hep-ex/0504037 Polnye rezul'taty pyatiletnei raboty solnechnoi neitrinnoi observatorii GNO (Complete results for five years of GNO solar neutrino observations) Authors: GNO COLLABORATION: M.

Migel' Chervin'o sdelal uzhe neskol'ko ochen' interesnyh rabot, posvyashennyh predelam primenimosti evolyucionnogo populyacionnogo sinteza. Kak vidno iz nazvaniya, eto chetvertaya rabota v serii. Rabota dostatochno tehnicheskaya, no na moi vzglyad vazhnaya. astro-ph/0504486 E = mc^2 Bez otnositel'nosti (E = mc^2 Without Relativity) Authors: Andrew Gould Comments: 4 pages + 1 figure. To be submitted to ApJ Eto ne populyarnaya stat'ya! Avtor (izvestnyi astrofizik) pokazyvaet, chto znamenitoe E=mc2 mozhno bylo by poluchit' za neskol'ko desyatiletii do Einshteina, t.k. avtoru udalos' naiti vyvod etoi formuly bez ispol'zovaniya relyativizma. Bylo by interesno uvidet' obsuzhdenie etoi raboty na forumah. katalog astro-ph/0504489 Katalog peremennyh UF istochnikov Galex (The Galex Ultraviolet Variability (GUVV) Catalog) Authors: Barry Y.

V dissertacii rassmatrivaetsya dva aspekta proekta. Vtoroi - bolee tehnicheskii, i ya ne budu o nem upominat'. A vot pervyi .... Eto sobstvenno spisok zvezd, kotorye budut nablyudat'sya. Vse, kogo ser'ezno interesuet poisk vnesolnechnyh planet tipa Zemli, priglashayutsya k prochteniyu. dissertaciya astro-ph/0504498 Gamma-izluchenie ot mikrokvazarov (Gamma-Ray Emission from Microquasars) Authors: M.M. Kaufman Bernado Comments: PhD Thesis supervised by G.E. Romero and presented at the University of Buenos Aires (UBA) on December 15th, 2004 V dissertacii mikrokvazary (akkreciruyushie dvoinye s relyativistskimi dzhetami) obsuzhdayutsya kak vozmozhnye neotozhdestvlennye istochniki, nablyudavshiesya priborom EGRET. miniobzor astro-ph/0504501 Ot malen'kih vzryvov k Bol'shomu Vzryvu (From Little Bangs to the Big Bang) Authors: John Ellis Comments: Invited Plenary Talk at the International Conference on the Physics and Astrophysics of the Quark-Gluon Plasma, Kolkata, Feb. 2005: 13 pages, 11 figures, uses IoP style files "Malen'kie vzryvy" - eto sobytiya stolknoveniya energichnyh chastic na kollaiderah - uskoritelyah na vstrechnyh puchkah. V pechati aktivno obsuzhdaetsya eta tema. Naibolee tipichnyi zagolovok "Fiziki vosproizveli Bol'shoi vzryv v laboratorii". Kak na samom dele sootnosyatsya "malen'kie vzryvy" i Bol'shoi vzryv mozhno uznat' iz etogo obzora, napisannogo odnim iz vedushih specialistov po kosmologii i fizike elementarnyh chastic. obzor astro-ph/0504517 Sverhnovye prolivayut svet na gamma-vspleski (Supernovae Shedding Light on Gamma-Ray Bursts) Authors: M.

Il Nuovo Cimento Obnaruzheno, chto nekotorye gamma-vspleski soprovozhdayutsya vspyshkami, pohozhimi na sverhnovye. Eti sverhnovye otlichayutsya ot bol'shinstva drugih, no pri etom sami ne sostavlyayut kakogo-to odnorodnogo klassa. V stat'e daetsya podrobnyi obzor nablyudatel'nogo materiala po svyazi kosmicheskih gamma-vspleskov so sverhnovymi. astro-ph/0504584 Statisticheskoe issledovanie sobstvennyh dvizhenii 233 pul'sarov (A statistical study of 233 pulsar proper motions) Authors: G. Hobbs, D. R. Lorimer, A. G. Lyne, M. Kramer Comments: 20 pages, accepted by MNRAS Ochen' vazhnaya rabota dlya vseh, kto zanimaetsya neitronnymi zvezdami. Odnim iz vazhnyh parametrov neitronnoi zvezdy yavlyaetsya ee skorost' v moment rozhdeniya. Delo v tom, chto vo vremya vzryva sverhnovoi (ili srazu posle nego) znachitel'naya energiya mozhet byt' vydelena asimmetrichno, chto privedet k tomu, chto novorozhdennyi kompaktnyi ob'ekt poluchit tolchok (ego nazyvayut kik - kick). Udar mozhet byt' ochen' chuvstvitel'nym - neitronnaya zvezda mozhet razognat'sya do tysyach km/s! Vysokaya nachal'naya skorost' mozhet predopredelit' opredelennyi evolyucionnyi put' neitronnoi zvezdy v budushem. Naprimer, esli ona rodilas' v dvoinoi sisteme, to sistema mozhet byt' razrushena. Poetomu opredelenie raspredeleniya neitronnyh zvezd po skorostyam yavlyaetsya vazhneishei zadachei. Naibol'shaya populyaciya neitronnyh zvezd - radiopul'sary. Mozhno nablyudat' ih sobstvennoe dvizhenie (na nebesnoi ploskosti). Togda, esli izvestno rasstoyanie, to mozhno opredelit' skorost' zvezdy v nebesnoi ploskosti. Dalee, esli schitat', chto skorosti raspredeleny sluchaino, mozhno poluchit' i ocenku istinoi (trehmernoi) skorosti. Takie raboty vedutsya s 70-h gg. Do poyavleniya dannoi stat'i naibolee obsheprinyatym raspredeleniem nachal'nyh skorostei neitronnyh zvezd schitalos' poluchennoe Arzumanyanom, Chernovym i Kordessom v 2002 g. Eto raspredelenie obladalo vazhnoi osobennost'yu - avtory obnaruzhili dve komponenty (dve mody). Srednyaya skorost' v pervoi mode - okolo 100 km/s, vo vtoroi - okolo 700 km/s. Poyavilos' mnozhestvo rabot, v kotoryh raznye avtory pytalis' ob'yasnit' etu bimodal'nost'. I vot .... I vot avtory dannoi stat'i na osnovanii issledovaniya sobstvennyh dvizhenii 233 radiopul'sarov otvergayut bimodal'nost'! Srazu skazhem, rezul'tat nuzhdaetsya v proverke. Eto ne iz nedoveriya k avtoram. Prosto pereschet nablyudaemogo raspredeleniya skorostei na nachal'noe raspredelenie yavlyaetsya ochen' slozhnoi zadachei s mnozhestvom neizvestnyh parametrov. Poetomu predpolozhim, chto stat'ya vyzovet diskussiyu. Te zhe samye vhodnye dannye budut ispol'zovany neskol'kimi gruppami dlya polucheniya nachal'nogo raspredeleniya po skorostyam. astro-ph/0504585 Otkrytie kol'ca Einshteina na bol'shom krasnom smeshenii (Discovery of a high-redshift Einstein ring) Authors: R.

Interesno tut to, chto vo-pervyh, my vidim (pust' i ne ideal'noe) kol'co Einshteina, a vo-vtoryh to, chto i linza i istochnik nahodyatsya na bol'shih krasnyh smesheniyah. Linza imeet z=0.986, a istochnik z=3.773. astro-ph/0504668 Klassifikaciya materinskih galaktik sverhnovyh (Classifications of the Host Galaxies of Supernovae, Set III) Authors: Sidney van den Bergh et al. Comments: Accepted for publishing in PASP Izuchena statistika poyavleniya sverhnovyh razlichnyh tipov v raznyh galaktikah. Vyborka sostavlyaet 604 sverhnovye. Otmetim odnu osobennost'. Sverhnovye tipa Ia mozhno razdelit' na dva tipa, tipichnymi predstavitelyami kotoryh yavlyayutsya SN 1991bg i SN 1991T. Tak vot pervyi tip v osnovnom nablyudaetsya v E i E/Sa galaktikah, a vtoroi - v galaktikah promezhutochnyh tipov. My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing). physics/0504179 Einshtein i Gilbert: Sozdanie Obshei teorii otnositel'nosti (Einstein and Hilbert: The Creation of General Relativity) Authors: Ivan T.
