    Korotkie gamma-vspleski

    Vpervye s vysokoi tochnost'yu udalos' lokalizovat' korotkii gamma-vsplesk GRB 050509B. Eto vyzvalo potok publikacii. Zatem udalos' opredelit' tochnye polozheniya eshe dlya treh.

    V etot vypusk my vklyuchili stat'yu Materinskie galaktiki i okruzhenie korotkih gamma-vspleskov . Kak yasno iz nazvaniya rech' idet ob issledovanii svoistv galaktik, v kotoryh proizoshli vspyshki. Krome togo, v Arhive poyavilas' napravlennaya v Nature stat'ya, posvyashennaya otkrytiyu vspleska GRB 050709, dlya kotorogo udalos' otnablyudat' ne tol'ko gamma, no i opticheskuyu vspyshku.

    astro-ph/0510011 Zatmeniya i modulyacii s orbital'nym periodom v dvoinom pul'sare PSR J0737-3039 (Eclipses and orbital modulations in binary pulsar PSR J0737-3039)
    Authors: Maxim Lyutikov
    Comments: 10 pages, 3 figures, solicited talk, topical session on PSR J0737-3039, A life with stars, a meeting in honor of Ed van den Heuvel

    Predstavlena fenomenologicheskaya model' dvoinogo pul'sara J0737-3039. Za schet togo, chto sistema s dvumya aktivnymi pul'sarami nablyudaetsya nami fakticheski s rebra, udaetsya registrirovat' ochen' interesnye variacii potokov izlucheniya ot pul'sarov. V ramkah prostoi modeli prakticheski vse eti variacii udaetsya ob'yasnit'.


    astro-ph/0510016 Proishozhdenie kosmicheskih luchei (The Origin of Cosmic Rays)
    Authors: A.D.Erlykin, A.W.Wolfendale
    Comments: 38 pages, 10 figures, accepted by J.Phys.G: Nucl. Part. Phys.It

    Obsuzhdaetsya proishozhdenie vysokoenergichnyh chastic kosmicheskih luchei. Chasticy s energiyami men'she t.n. "kolena" svyazyvayut s ostatkami sverhnovyh v nashei Galaktike. Dlya bolee vysokih energii situaciya menee yasna. Avtory rassmatrivayut razlichnye ob'ekty v Galaktike, sposobnye uskoryat' chasticy do stol' vysokih energii. Osnovnoi vyvod avtorov sostoit v tom, chto nailuchshimi kandidatami byli by udarnye volny v galakticheskom galo.


    astro-ph/0510018 Gamma vspleski i perehod k kvarkovoi materii v kvarkovyh zvezdah (Gamma Ray Bursts and the transition to Quark Matter in Compact Stars)
    Authors: A. Drago et al.
    Comments: 4 pages, 1 figure, Proceedings QM2005, August 2005 Budapest

    Odnoi iz modelei gamma-vspleska yavlyaetsya perehod veshestva neitronnoi zvezdy v kvarkovoe sostoyanie. T.k., soglasno gipoteze Bodmera-Vittena imenno kvarkovoe veshestvo yavlyaetsya energeticheski bolee vygodnym, to pri takom perehode budet za korotkoe vremya vydelena gigantskaya energiya. Avtory obsuzhdayut osnovnye svoistva takoi modeli i sravnivayut ee s nablyudeniyami.


    astro-ph/0510022 Materinskie galaktiki i okruzhenie korotkih gamma-vspleskov (The Galaxy Hosts and Large-Scale Environments of Short-Hard $\gamma$-ray Bursts)
    Authors: J. X. Prochaska et al.
    Comments: 14 pages, 2 figures. Submitted to ApJL

    Rassmotreny materinskie galaktiki chetyreh korotkih gamma-vspleskov. Tri iz nih - eto starye massivnye galaktiki s ochen' nizkim sovremennym tempom zvezdoobrazovaniya (vse galaktiki nahodyatsya na nebol'shih krasnyh smesheniyah). Chetvertaya - eto karlikovaya galaktika s zametnym zvezdoobrazovaniem.

    Avtory zaklyuchayut, chto podobno sverhnovym tipa Ia korotkie gamma-vspleski mogut poyavlyat'sya v galaktikah raznyh tipov.


    obzor astro-ph/0510025 Populyacii zvezd v Galaktike (Galactic Stellar Populations)
    Authors: Rosemary F.G. Wyse, Gerard Gilmore
    Comments: 19 pages, invited review at the Cozumel/Cancun conference on Resolved Stellar Populations, April 2005. ASP Conference proceedings, eds D. Valls-Gabaud and M. Chavez

    Obsuzhdaetsya, kak po nablyudeniyam zvezd mozhno vosstanovit' istoriyu Mlechnogo Puti, vklyuchaya epizody poglosheniya galaktik-sputnikov.


    astro-ph/0510058 Gamma-vspleski, svyazannye so sverhnovymi: sistematicheskii analiz kandidatov BATSE (Gamma--Ray Bursts associated with Supernovae: A systematic analysis of BATSE GRB candidates)
    Authors: Z. Bosnjak et al.
    Comments: 12 pages, 8 figures, 1 table - accepted for publication in A&A

    Vo vremena raboty sputnika CGRO s priborami eksperimenta BATSE vozmozhnaya associaciya gamma-vspleskov so sverhnovymi obsuzhdalas' ne stol' aktivno kak seichas. K tomu zhe plohoe uglovoe razreshenie BATSE ne davalo vozmozhnosti delat' skol'-nibud' horoshie otozhdestvleniya vspleskov. Tem ne menee ital'yanskie avtory reshili provesti korrelyaciyu dannyh BATSE s katalogami sverhnovyh.

    Ukazhem na dva interesnyh vyvoda raboty. Pervyi sostoit v tom, chto gamma-vspleski, kotorye vozmozhno svyazany so sverhnovymi, imeyut (v 80 procentov sluchaev) prostuyu odnopikovuyu strukturu. Vtoroi -- v tom, chto eti vspleski okazyvayutsya bolee myagkimi.

    Avtory ukazyvayut, chto dolya sverhnovyh tipa Ibc v poluchennoi vyborke okazalas' v 4 raza vyshe, chem v ishodnom nabore sverhnovyh. Eto ukazyvaet, po ih mneniyu, na to, chto eti sverhnovye i vpryam' mogut byt' svyazany s gamma-vspleskami.


    obzor hep-ph/0509309 ILC Kosmologiya (ILC Cosmology)
    Authors: Jonathan L. Feng
    Comments: 18 pages, Plenary Colloquium presented at the 2005 International Linear Collider Workshop, Stanford, California, USA, 18-22 March 2005

    ILC - International Linear Collider.

    Tradicionno kosmologicheskie issledovaniya svyazyvayut s rabotami po fizike elementarnyh chastic. Otsyuda takie terminy kak kosmomikrofizika, particle astrophysics, i astroparticle physics. Avtor daet obzor nekotoryh problem sovremennoi kosmologii i rassuzhdaet, kak v ih reshenii mogut pomoch' sovremennye uskoriteli.


    astro-ph/0510190 Otkrytie korotkogo gamma-vspleska GRB 050709 (Discovery of the short gamma-ray burst GRB 050709)
    Authors: J. S. Villasenor et al.
    Comments: 19 pages, 4 figures. Submitted to Nature

    Opisyvaetsya otkrytie korotkogo gamma-vspleska, dlya kotorogo vpervye udalos' poluchit' dannye i v optike. Fakticheski, imenno s etoi raboty nachinaetsya novaya stranica v issledovanii korotkih gamma-vspleskov.


    astro-ph/0510309 Izuchenie ochen' korotkih gamma-vspleskov: novye rezul'taty s BATSE i KONUS (Study of Very Short GRB: New Results from BATSE and KONUS)
    Authors: D.B. Cline, B. Czerny, C. Matthey, A. Janiuk, S. Otwinowski
    Comments: accepted for ApJ Letters

    Avtory prodolzhayut svoi issledovaniya ochen' korotkih gamma-vspleskov. Rech' idet o vspleskah dlitel'nost'yu menee 0.1 sekundy. ispol'zovany dannye BATSE i KONUS.

    Avtory nastaivayut na tom, chto eto osobyi (tretii) klass vspleskov. Krome dlitel'nosti on vydelyaetsya zhestkost'yu spektra (vidyat fotony do neskol'kih MeV) i raspredeleniem. Poslednee neizotropno s yavnym izbytkom vspleskov v napravlenii na anticentr Galaktiki. Kakie galakticheskie ob'ekty mogut davat' takie vspyshki - neizvestno. Avtory spekuliruyut ob isparenii chernyh dyr. Neyasno, pravda, pochemu dyry skoncentrirovany v napravlenii na anticentr.


    astro-ph/0510315 Dve populyacii praroditelei sverhnovyh tipa Ia (Two populations of progenitors for type Ia SNe)
    Authors: F. Mannucci, M. Della Valle, N. Panagia
    Comments: 9 pages, 6 figures, MNRAS, revised version after referee's comments

    Avtory pokazyvayut, chto sverhnovye tipa Ia raspadayutsya na dva klassa. Dlya odnogo iz nih vzryv proishodit spustya primerno 0.1 milliarda let posle obrazovaniya zvezdy, a dlya vtorogo eto vremya sostavlyaet uzhe milliardy let (v srednem poryadka treh).


    astro-ph/0510381 Registraciya ochen' yarkoi opticheskoi vspyshki ot gamma-vspleska na krasnom smeshenii 6.29 (Detection of a very bright optical flare from a gamma-ray burst at redshift 6.29)
    Authors: Michel Boer et al.
    Comments: 13 pages, 3 figures. Submitted to Nature, posted for scientific use only

    25-santimetrovyi avtomaticheskii teleskop TAROT smog zafiksirovat' opticheskuyu vspyshku ot samogo dalekogo iz vseh otkrytyh na segodnyashnii den' gamma-vspleskov! Tranzient dostig v maksimume 9-i zvezdnoi velichiny.
