    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.

    astro-ph/0505191 INTEGRAL IGR J18135-1751=HESS J1813-178: novyi kosmicheskii uskoritel' vysokih energii ot keV do TeV (INTEGRAL IGR J18135-1751=HESS J1813-178: A new cosmic high energy accelerator from keV to TeV)
    Authors: Ubertini et al.
    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.

    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. Saz Parkinson (Milagro Collaboration) Comments: Talk presented at the "Rencontres de Moriond: Very High Energy Phenomena in the Universe" at La Thuile, Italy (March 12-19, 2005), http://moriond.in2p3.fr/J05/. 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.




    My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing).

    Authors: J. R. Mureika, G. C. Cupchik, C. C. Dyer
    Comments: 13 pages, 8 ps figures; Leonardo 37 (1), 53-56 (February 2004)

    Avtory obsuzhdayut kak s pomosh'yu mul'tifraktal'nogo analiza mozhno vyyavlyat' podlinnost' poloten hudozhnikov, rabotavshih v manere "zhestikulyacionnogo ekspressionizma" (gestural expressionism).
