Obzory preprintov astro-ph Vypusk N107 astro-ph za 11 - 19 maya 2005 goda: izbrannye stat'i Goryachie temy nedeli Rezul'taty HESS i ih obsuzhdenie Idet potok dannyh ot observatorii HESS. My uzhe rasskazyvali ob otkrytii vos'mi istochnikov v ploskosti Galaktiki. Dva iz nih byli neotozhdestvleny v drugih diapazonah. Nedavno poyavilas' rabota, v kotoroi otozhdestvlenie odnogo iz nih bylo sdelano s pomosh'yu sputnika Integral. Novye rezul'taty HESS predstavleny eshe v neskol'kih svezhih rabotah: Serendipitous discovery of the unidentified extended TeV gamma-ray source HESS J1303-631 i Detection of TeV gamma-ray Emission from the Shell-Type Supernova Remnant RX J0852.0-4622 with H.E.S.S. Nekotorye raboty mozhno budet obsudit' 20-go maya na seminare OSA.

Comments: Submitted to ApJ Letters; 12 pages, 3 Figures V konce aprelya ya uzhe rasskazyval ob otkrytii novyh gamma istochnikov observatoriei HESS. Napomnyu, chto dlya dvuh iz nih ne bylo naideno sootvetstvuyushih ob'ektov v radio i rentgenovskom diapazone. Odnako Ubertini s kollegami smogli obnaruzhit' odin iz etih dvuh zagadochnyh istochnikov s pomosh'yu sputnika Integral. Na vernem risunke pokazano izobrazhenie, poluchennoe INTEGRALOM. Interesuyushii nas istochnik sprava. Zelenym kruzhkom oboznachen istochnik HESS. Na nizhnem risunke pokazano radioizobrazhenie, poluchennoe na VLA v ramkah obzora neba. Krugi i ellipsy sootvetstvuyut oblastyam lokalizacii istochnika po dannym rentgenovskih sputnikov i HESS. Priroda istochnika ostaetsya neizvestnoi. Avtory obsuzhdayut vozmozhnost' togo, chto eto pul'sarnaya tumannost' ili radiopul'sar v tesnoi dvoinoi sisteme. obzor hep-th/0505050 Fundamental'nye kosmicheskie struny (Fundamental cosmic strings) Authors: A.-C. Davis, T.W.B. Kibble Comments: Review to appear in Contemporary Physics Obzor po kosmicheskim strunam. Posvyashen on novym ideyam v etoi oblasti. Delo v tom, chto original'nyi scenarii, predlozhennyi Kibblom, po suti dela zakryt nablyudeniyami. Odnako novye teorii "mira na brane" otkryvayut novye vozmozhnosti. astro-ph/0505219 Sluchainoe otkrytie neotozhdestvlennogo protyazhennogo TeV-nogo gamma-istochnika HESS J1303-631 (Serendipitous discovery of the unidentified extended TeV gamma-ray source HESS J1303-631) Authors: H.E.S.S. Collaboration: F. Aharonian, et al Comments: 9 pages, 8 figures, accepted in Astronomy and Astrophysics Eshe odin novyi neotozhdestvlennyi istochnik otkryt observatoriei HESS. Na etot raz istochnik protyazhennyi. Otkrytie nazvano serendipicheskim, t.k. nablyudalas' dvoinaya sistema PSR B1259-63/SS 2883. Kak obychno byvaet s neotozhdestvelnnymi istochnikami v gamma-diapazone, priroda novogo ob'ekta ostaetsya poka neponyatoi. astro-ph/0505255 Otkrytie bystryh rentgenovskih oscillyacii v hvoste gipervspyshki SGR 1806-20 (Discovery of Rapid X-ray Oscillations in the Tail of the SGR 1806-20 Hyperflare) Authors: GianLuca Israel et al. Comments: Accepted for publication on ApJ Letters. 4 Pages, 3 figures. emulateapj5 style used Po dannym rentgenovskogo sputnika RXTE otkryty kvaziperiodicheskie kolebaniya v hvoste moshnoi vspyshki istochnika myagkih povtoryayushihsya vspleskov (MPG) SGR 1806-20. Eto pervoe otkrytie takogo roda. Vozmozhno, chto ono pomozhet prolit' svet na prirodu gigantskih vspyshek MPG. astro-ph/0505292 Istochniki ROSAT v pustyh polyah (Blank Field Sources in the ROSAT HRI Brera Multiscale Wavelet catalog) Authors: M. Chieregato et al. Comments: 10 pages, 5 figures, accepted for publication on A&A Avtory popytalis' vydelit' sredi istochnikov ROSAT te, kotorye ne imeyut otozhdestvlenii v drugih diapazonah. Posle otbrasyvaniya oblastei s vysokoi plotnost'yu ob'ektov (tam ochen' trudno provodit' otozhdestvleniya) avtory smogli vydelit' chetyre takih istochnika. Povtoryus', eto istochniki, vidimye v myagkom rentgenovskom diapazone, no nevidimye v drugih. Avtory obsuzhdayut vozmozhnuyu prirodu etih ob'ektov. Po suti est' chetyre versii: eto odinochnye neitronnye zvezdy (imenno poisk takih ob'ektov posluzhil motivaciei vsego proekta), aktivnye yadra galaktik (lacertidy, v pervuyu ochered'), skopleniya galaktik (svetit goryachii gaz), i tesnye dvoinye sistemy. obzor gr-qc/0505057 Elementy kosmologii v ramkah petlevoi kvantovoi gravitacii (Elements of Loop Quantum Cosmology) Authors: Martin Bojowald Comments: 30 pages, 4 figures, Chapter contributed to "100 Years of Relativity - Space-time Structure: Einstein and Beyond", Ed. A. Ashtekar (World Scientific) Kak izvestno, naibolee razrabotannoi teoriei, pretenduyushei na "vseobshnost'" yavlyaetsya teoriya strun. Odnako u nee est' i konkurenty. Naibolee sil'nym i perspektivnym schitaetsya teoriya petlevoi kvantovoi gravitacii. V dannom obzore rassmotreny kosmologicheskie prilozheniya etoi teorii. astro-ph/0505300 Unifikaciya AYaG i rentgenovskii fon (AGN Unification and the X-ray Background) Authors: Ezequiel Treister, C.M. Urry Comments: 19 pages, 6 figures, accepted by The Astrophysical Journal "Unifikaciya AYaG" - eto popytka edinogo opisaniya razlichnyh tipov aktivnyh yader galaktik. V teorii var'iruetsya massa chernoi dyry, stepen' "zakrytosti" central'nogo istochnika pogloshayushei materiei, i orientaciya sistemy otnositel'no nas. Teoriya razvivaetsya dostatochno davno i ee aktivno sravnivayut s dannymi nablyudenii. V etoi stat'e avtory pokazyvayut, chto krome vsego prochego teoriya horosho opisyvaet dannye po rentgenovskomu fonu. miniobzor astro-ph/0505335 Svezhie rezul'taty gamma-observatorii Milagro (Recent results from the Milagro TeV gamma-ray observatory) Authors: P.M. Saz Parkinson (Milagro Collaboration) Comments: .M.

To appear in the conference proceedings Dana svodka poslednih rezul'tatov gamma-observatorii Milagro. Krome verhnih predelov est' i real'nye detektirovaniya! gr-qc/0505076 Poisk gravitacionnyh voln ot izvestnyh pul'sarov (Searching for gravitational waves from known pulsars) Authors: Matthew Pitkin, for the LIGO Scientific Collaboration Comments: Accepted by CQG for the proceeding of GWDAW9, 7 pages, 2 figures A vot zdes' est' tol'ko verhnie predely. Komanda LIGO predstavlyaet novye ogranicheniya na potok gravitacionnyh voln ot 28 izvestnyh pul'sarov. astro-ph/0505370 "Fabrika sverhnovyh" v Mrk 273? (A Supernova Factory in Mrk 273?) Authors: M. Bondi et al. Comments: Accepted for publication in Monthly Notices of the Royal Astronomical Society Main Journal. 6 pages, 3 figures Sredi galaktik s burnym zvezdoobrazovaniem inogda vydelyayut t.n. "fabriki sverhnovyh". V etih ob'ektah temp vspyshek ochen' velik (odna sverhnovaya v god i dazhe bol'she). Sredi otnositel'no blizkih galaktik (rasstoyanie poryadka 40 Mpk) k etomu tipu mozhno otnesti Arp 299 i NGC 3256. Takie sistemy predstavlyayut bol'shoi interes ne tol'ko dlya astronomov, izuchayushih sobstvenno galaktiki i zvezdoobrazovanie. Vysokii temp sverhnovyh oznachaet i vysokii temp rozhdeniya neitronnyh zvezd i chernyh dyr, a takzhe vysokii temp generacii kosmicheskih luchei. T.o. i dlya vysokih energii "fabriki sverhnovyh" predstavlyayut bol'shoi interes. Mrk 273 nahoditsya na rasstoyanii 150 Mpk (z=0.0378). Avtory proveli detal'nye radionablyudeniya etoi galaktiki. Oni vyyavili struktury, kotorye svidetel'stvuyut o tom, chto i etot ob'ekt mozhno otnesti k "fabrikam sverhnovyh". Temp ocenivaetsya v 1.5 vspyshek v god. Temp zvezdoobrazovaniya poryadka 39 mass solnca v god, i dlitsya takaya aktivnost' neskol'ko desyatkov millionov let. astro-ph/0505380 Registraciya TeVnogo izlucheniya ot ostatka sverhnovoi RX J0852.0-4622 (Detection of TeV gamma-ray Emission from the Shell-Type Supernova Remnant RX J0852.0-4622 with H.E.S.S) Authors: H.E.S.S. collaboration: F. Aharonian, et al Comments: 5 pages, 3 figures, accepted for publication in A&A letters Observatoriya HESS smogla zaregistrirovat' gamma-izluchenie ot obolochechnogo ostatka sverhnovoi RX J0852.0-4622. Detektirovanie vpolne otchetlivoe, odnako dlya kakih-to sushestvenno interesnyh vyvodov neobhodimy dal'neishie nablyudeniya.
