Recchi1 & G. Hensler Comments: A&A, 13 pages Bogatye gazom karlikovye galaktiki podrazdelyayut na karlikovye irregulyarnye nizkoi poverhnostnoi yarkosti (dIrr), i yarkie golubye karlikovye galaktiki (BCD).

Rassmotrena ih evolyuciya c uchetom radiacionnogo vliyaniya pervyh zvezd (zvezd naseleniya III). Soglasno raschetam avtorov stat'i, v rezul'tate dinamicheskogo vliyaniya zvezd naseleniya III karlikovye galaktiki teryayut do 40% vseh tyazhelyh elementov i obogashayut mezhgalakticheskuyu sredu na samyh rannih etapah evolyucii Vselennoi. arxiv:0710.3165 Chernaya dyra s massoi 15.65 solnechnyh v zatmennoi dvoinoi sisteme v blizkoi spiral'noi galaktike M33 (A 15.65 solar mass black hole in an eclipsing binary in the nearby spiral galaxy Messier 33) Authors: Jerome A. Orosz et al. Comments: To appear in Nature October 18, 2007. Four figures (one color figure degraded). Differs slightly from published version. Supplementary Information follows in a separate posting Avtory soobshayut o tom, chto ocenka massy chernoi dyry v odnoi iz vnegalakticheskih tesnyh dvoinyh sistem okazalos' dovol'no vysokoi - okolo 16 mass Solnca. Eto rekord. Ocenku udalos' sdelat' blagodarya tomu, chto v sisteme nablyudayut zatmeniya, t.e. my vidim ee pochti s rebra. Eto pozvolyaet poluchit' ne tol'ko nizhnii predel (funkciyu mass), no i ocenku massy chernoi dyry. Otmechu, chto vse-taki ne stoit preuvelichivat' tochnost' ocenki. Sami avtory govoryat o 14-17 mass Solnca, no eto ne znachit, chto ne mozhet byt' i 13, ili 12 .... Poyavlenie takih chernyh dyr ne yavlyaetsya chem-to neozhidannym. Raschety pozvolyayut poluchat' i neskol'ko bolee massivnye chernye dyry v rezul'tate normal'nogo kollapsa yader massivnyh zvezd (drugoe delo, chto v dvoinoi sisteme poyavlyayutsya dopolnitel'nye slozhnosti - massa "utekaet" na zvezdu-sosedku ili rasseivaetsya v prostranstve na t.n. stadii "obshei obolochki"). Tem ne menee, esli ocenka podtverditsya, rezul'tat kraine vazhen, ibo raschety raschetami, a astronomiya - nauka nablyudatel'naya.

Leonard Comments: Accepted for publication in The Astrophysical Journal. 16 pages, 1 figure Vazhnaya rabota, na moi vzglyad. Ideya tut vot v chem. Est' sverhnovye tipa Ia (eto po nim izmeryayut uskorenie rasshireniya vselennoi i tp.). Polagayut, chto eto vzryv belogo karlika. Massa karlika rosla-rosla za schet akkrecii s soseda, poka ne dorosla.... Tak vot. Esli akkreciruemoe veshestvo bogato vodorodom, kak eto i predpolagaetsya vo mnogih scenariyah, to posle vzryva etot vodorod mozhno uvidet' po spektram. Detal'ki tam budut slaben'kie, no vpolne obnaruzhimye. Sut' v tom, chto dlya dvuh sverhnovyh takie detal'ki poiskali, da ne nashli. T.e., postavili zhestkii predel na massu vodoroda. Takoi zhestkii, chto mnogie scenarii okazalis' zakrytymi. Budem posmotret', chto pridumayut teoretiki v otvet!

Kompleks C (Distances to Galactic high-velocity clouds. Complex C) Authors: B.P. Wakker et al. Comments: ApJ Let, 12 pages Evolyuciya galaktik polnost'yu opredelyaetsya kolichestvom mezhzvezdnogo gaza. Chem bol'she gaza, tem bolee prodolzhitel'na evolyuciya. Strogoi granicy mezhdu galaktikami i mezhgalakticheskoi sredoi ne sushestvuet, proishodit postoyannyi obmen. Obogashennyi metallami gaz pokidaet galaktiku v vide galakticheskogo vetra, a nizkometallichnyi gaz akkreciruetsya iz mezhgalakticheskoi sredy. Nalichie akkrecii gaza s nizkim soderzhaniem tyazhelyh elementov kosvenno sleduet iz modelei himicheskoi evolyucii, poskol'ku nalichie akkrecii neobhodimo dlya ob'yasneniya obshirnogo nablyudatel'nogo materiala. Neposredstvennym dokazatel'stvom popolneniya Galaktiki gazom sluzhit sushestvovanie vysokoskorostnyh oblakov (VSO) - protyazhennyh oblakov neitral'nogo gaza, imeyushih skorost' poryadka 100 km/s otnositel'no Galaktiki. Avtory dannoi raboty proanalizirovali rasstoyanie do sistemy oblakov "kompleks S". Dannaya stat'ya - prodolzhenie ih rabot na etu temu (k primeru, astro-ph 0709.1926). Sut' metoda prosta: v napravlenii vysokoskorostnogo oblaka vybirayutsya zvezdy, rasstoyaniya do kotoryh izvestny s horoshei tochnost'yu. Ocenku rasstoyaniya do oblaka mozhno poluchit', izuchaya linii mezhzvezdnogo poglosheniya v spektrah etih zvezd. Nablyudeniya provedeny avtorami v observatoriyah McDonald, Keck i WHT. V rabote ispol'zovany dannye radionablyudenii. Po mneniyu avtorov, rasstoyanie do oblaka "kompleks S" nahoditsya v predelah ot 3.7 kpk (po drugoi ocenke 6.7 kpk) do 11.2 kpk. Ocenka rasstoyaniya provedena vpervye. Bol'shoi interval v neskol'ko kiloparsek svyazan kak s protyazhennost'yu samogo oblaka, imeyushego bol'shoi uglovoi diametr, tak i s neobhodimost'yu utochneniya etogo rezul'tata s pomosh'yu dal'neishih nablyudenii. Metallichnost' "kompleksa S" sostavlyaet 15% ot solnechnoi. Izmerenie kolichestva neitral'nogo vodoroda vdol' oblaka po luchu zreniya pozvolilo ocenit' massu neitral'nogo vodoroda. Nablyudenii v linii H_alpha pokazali, chto soderzhanie neitral'nogo i ionizovannogo gaza v oblake primerno odinakovy. Obshaya ocenka massy oblaka sostavila 3.-14. x 106 solnechnyh mass, chto sootvetstvuet tempu akkrecii 0.1-0.25 mass Solnca/god. Obshii temp akkrecii mezhgalakticheskogo gaza Galaktikoi ocenivaetsya kak 1 massa Solnca/god, potomu vklad oblaka "kompleks S" sostavlyaet ot 10 do 25%. Rasstoyanie do vysokoskorostnyh oblakov ostavalos' zagadkoi dolgoe vremya. Sovremennye nablyudeniya pokazyvayut, chto VSO nahodyatsya v predelah galo Galaktiki, a ih nizkaya metallichnost' i napravlenie dvizheniya podtverzhdayut tot fakt, chto Galaktika na protyazhenii vsei evolyucii nepreryvno "podpityvaetsya" gazom izvne. Zadachei posleduyushih issledovanii budet postroenie trehmernoi karty raspredeleniya VSO. arxiv:0710.3381 Chernaya dyra v sharovom skoplenii, izluchayushaya v rentgene (An X-ray emitting black hole in a globular cluster) Authors: Thomas J. Maccarone et al. Comments: 5 pages, 2 figures, to appear in the proceedings of IAUS 246, "Dynamical Evolution of Dense Stellar Systems", ed. Vesperini, Giersz and Sills Esli eto podtverditsya, to eto kuda kak interesnee, chem chernaya dyra s massoi 15 mass solnca. Dolgoe vremya schitali, chto v sharovyh skopleniyah dolzhny byt' chernye dyry, i chto oni dolzhny izluchat' v rentgene. No za 40 s lishnim let rentgenovskoi astronomii nikto tak nichego i ne nashel. Bolee togo, net ni odnoi chetko podtverzhdennoi ("chetko" na urovne drugih sil'nyh kandidatov v chernye dyry) chernoi dyry v sharovyh skopleniyah po dannym lyubyh nablyudenii (hotya nekotorye ukazaniya na ih sushestvovanie est', svyazany oni vse s dinamikoi zvezd v skopleniyah).

Svetimost' ochen' bol'shaya - pod 1040 erg/s. Istochnik sil'no peremennyi. Poluchen i opticheskii spektr, kotoryi, po mneniyu avtorov, govorit v pol'zu ih interpretacii. Sootvetstvenno, oni polny entuziazma i prizyvayut iskat' chernye dyry v dvoinyh sistemah v sharovyh skopleniyah Mlechnogo Puti (rech' idet o dyrah v spokoinom sostoyanii, kogda net moshnoi akkrecii, inache davno by uzhe otkryli).

Highlight talk presented at the 30th International Cosmic Ray Conference, Merida, Mexico, 2007 Neitrino samyh vysokih energii vozmozhno budut obnaruzheny ustanovkami tipa observatorii imeni Ozhe ili zhe kilometrovymi detektorami neitrino. Eto bylo by cherezvychaino sushestvennym otkrytiem. Neitrino ne otklonyayutsya magnitnym polem, poetomu oni pryamo ukazyvali by na istochniki (v otlichie ot protonov i yader v kosmicheskih luchah). O tom, kak mogut voznikat' neitrino sverhvysokih energii, kak ih "poimat' za borodu", i chto my smozhem uznat' s ih pomosh'yu mozhno prochest' v obzore. miniobzor arxiv:0710.4248 INTEGRAL - pyat' let raboty kosmicheskih detektorov izlucheniya vysokoi energii (INTEGRAL - operating high-energy detectors for five years in space) Authors: Volker Beckmann Comments: 10 pages. Invited review to appear in the proceedings of the 10th ICATPP conference, Como, Italy, October 8-12, 2007 Kak vremya letit! Vot uzhe pyat' let otrabotal sputnik INTEGRAL. Za eto vremya na nem sdelano mnogo interesnyh otkrytii. Na moi vzglyad, samoe interesnoe - eto obnaruzhenie zhestkih hvostov v spektrah magnitarov. No eto ochen' sub'ektivnyi vzglyad. Svoe mnenie vy smozhete sostavit', oznakomivshis' s predlagaemym obzorom. arxiv:0710.4280 Gamma-vspleski iz molodoi vselennoi: predskazaniya dlya sovremennyh i budushih instrumentov (Gamma Ray Bursts from the early Universe: predictions for present-day and future instruments) Authors: R. Salvaterra, S. Campana, G. Chincarini, S. Covino, G. Tagliaferri Comments: 6 pages, 2 figures, MNRAS in press Avtory zadayutsya voprosom: kakim dolzhen byt' ideal'nyi instrument dlya poiska gamma-vspleskov s bol'shim krasnym smesheniem. Takie vspleski pomogli by uznat' mnogo interesnogo ob epohe reionizacii. Ideal'nyi instrument sravnivaetsya s vozmozhnostyami sovremennyh priborov, a takzhe teh, kotorye poletyat v blizhaishem budushem. Po mneniyu avtorov ni INTEGRAL, ni GLAST ne smogut tut pomoch', a vot EXIST smozhet uvidet' dostatochnoe kolichestvo dalekih gamma-vspleskov. Sm. nizhe stat'yu o chuvstvitel'nosti EXIST k gamma-vspleskam. obzor arxiv:0710.4482 Nadezhnoe mashinnoe obuchenie v primenenii k terabaitnym astronomicheskim dannym (Robust Machine Learning Applied to Terascale Astronomical Datasets) Authors: Nicholas M. Ball, Robert J. Brunner, Adam D. Myers Comments: 4 pages, 1 figure, uses adassconf.sty, asp2006.sty. To appear in the proceedings of ADASS XVII, London, UK, Sep 2007 Rabota s bol'shimi sovremennymi obzorami, tipa Sloanovskogo, trebuet sovershenno novyh chislennyh metodov. Im i posvyashena dannaya stat'ya. Ideya sostoit v razrabotke algoritmov, pozvolyayushih komp'yuteru "obuchat'sya" klassificirovat' ob'ekty. obzor arxiv:0710.4602 Chuvstvitel'nost' EXIST k gamma-vspleskam (EXIST's Gamma-Ray Burst Sensitivity) Authors: D. L. Band et al. Comments: 25 pages, 10 figures, accepted by ApJ EXIST - eto sputnik dlya issledovaniya neba v zhestkom diapazone spektra. Ozhidaemyi zapusk - primerno v 2015 godu. V stat'e rassmotrena chuvstvitel'nost' pribora k gamma-vspleskam. Razumeetsya, chuvstvitel'nost' budushego apparata sushestvenno prevzoidet parametry sushestvuyushih priborov. miniobzor arxiv:0710.4909 Proishozhdenie galakticheskih kosmicheskih luchei (The origin of galactic cosmic rays) Authors: Joerg R. Hoerandel Comments: 8 pages, Invited talk given at the Roma International Conference on Astro-Particle physics (RICAP07) June 20th - 22nd, 2007. To be published in Nuclear Instruments and Methods A Nazvanie govorit samo za sebya. Sushestvenno, chto avtor rassmatrivaet samye raznye metody issledovaniya kosmicheskih luchei. Poetomu obzor poluchaetsya ochen' cel'nym. Kak polozheno, obzor zavershaetsya obsuzhdeniem nereshennyh problem i kratkim opisaniem budushih eksperimentov. miniobzor arxiv:0710.5026 Parksovskii nabor pul'sarov dlya taiminga (The Parkes Pulsar Timing Array) Authors: R. N. Manchester Comments: 9 pages, 6 figures, Proceedings of "40 Years of Pulsars: Millisecond Pulsars, Magnetars and More", Montreal, August 2007 Pul'sary "chuvstvuyut" gravitacionnye volny. Buduchi tochnymi chasami, oni "sbivayutsya", kogda prohodit gravvolna (krome togo, sboi budet nablyudat'sya i togda, kogda volna prohodit cherez Zemlyu). Poetomu, nablyudaya neskol'ko pul'sarov s horosho izvestnym taimingom, mozhno dat' ogranicheniya na gravvolny. T.e., pul'sary rabotayut kak gravitacionnye detektory. PPTA (Parkes Pulsar Timing Array) - eto kak raz nabor iz 20 ob'ektov dlya podobnyh issledovanii. Provodyatsya regulyarnye nablyudeniya etih pul'sarov, chto i pozvolyaet delat' vsyakie interesnye vyvody po povodu gravvoln (i ne tol'ko gravvoln, kstati). Poka, konechno, rech' idet tol'ko o verhnih predelah, no ved' i detektory poka nikakogo polozhitel'nogo rezul'tata v registracii gravsignala ne dali :) miniobzor arxiv:0710.5374 Vklad Kosmicheskogo teleskopa v izuchenie neitronnyh zvezd (The HST contribution to neutron star astronomy) Authors: R.P. Mignani Comments: 4 pages, to be published in Proc. of 41st ESLAB Symposium: The Impact of HST on European Astronomy V korotkom obzore Roberto Min'yani rasskazyvaet, kakuyu rol' sygrali nablyudeniya na habblovskom teleskope v astronomii neitronnyh zvezd. Neitronnye zvezdy yavlyayutsya ochen' slabymi istochnikami v opticheskom diapazone (za isklyucheniem pul'sarov v Krabe i Parusah, kotorye i byli prakticheski edinstvennymi horosho izuchennymi v optike neitronnymi zvezdami do zapuska Kosmicheskogo teleskopa). Poetomu neudivitel'no, chto ni o kakih massovyh otozhdestvleniyah etih ob'ektov s pomosh'yu nazemnyh teleskopov v 80-h godah i ranee ne bylo i rechi. S zapuskom Habbla situaciya rezko izmenilas': chislo otozhdestvlennyh v optike neitronnyh zvezd perevalilo za desyatok. Krome klassicheskih radiopul'sarov v optike nablyudayut Gemingu i nekotorye iz ob'ektov, vhodyashih v Velikolepnuyu semerku. O poiskah novyh kandidatov v ostyvayushie neitronnye zvezdy (tipa Velikolepnoi semerki) mozhno prochest' zdes': arxiv:0710.5192 My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing). arxiv:0710.4279 Eksperiment SuperNEMO po poisku dvoinogo beta-raspada (The SuperNEMO double beta decay experiment) Authors: Irina Nasteva, for the SuperNEMO Collaboration Comments: 6 pages, 2 figures; talk presented at the 10th ICATPP Conference, Como, Italy, 8-12 October 2007; to be published by World Scientific Obnaruzhenie bezneitrinnogo dvoinogo beta-raspada ochen' vazhno dlya fundamental'noi fiziki. V techenie poslednih desyatkov let postoyanno predprinimayutsya popytki uvidet' takoe sobytie. Poka - tol'ko verhnie predely. V stat'e opisan eshe odin proekt. Vernut'sya k nachalu stranicy
