Referaty otdel'nyh statei
Authors: Michael L. Norman et al. Comments: 22 pages, 6 figures. To appear in Petascale Computing: Algorithms and Applications, Ed. D. Bader, CRC Press LLC (2007) Podrobno, no ochen' ponyatno (bez massy formul i tp.) opisana komp'yuternaya programma i ee primeneniya dlya kosmologicheskih vychislenii. Rekomenduyu vsem, kto interesuetsya tem, kak provodyatsya moshnye vychisleniya v sovremennoi astrofizike.
Authors: Floor van Leeuwen et al. Comments: 9 pages, 1 figure, on-line material from mwf@artemisia.ast.uct.ac.za. Accepted for MNRAS Avtory ispol'zuyut peresmotrennye parallaksy cefeid, poluchennye s pomosh'yu sputnika Gipparkos. Ispol'zuya novye rezul'taty, oni peresmatrivayut rasstoyaniya do galaktik, ispol'zovavshihsya pri ocenke postoyannoi Habbla. V srednem ocenka postoyannoi vozrastaet primenrno na 10 procentov.
Authors: Bruno Binggeli, Tatjana Hascher Comments: 17 pages, 11 figures - Accepted for publication in PASP (review) Dovol'no interesnyi obzor, ibo zatragivaet prakticheski vse izvestnye astronomicheskie ob'ekty. Konkretno, avtory rassmatrivayut funkcii mass ob'ektov ot melkih asteroidov do skoplenii galaktik. V ochen' shirokom predele grubo mozhno opisat' "vselenskuyu" funkciyu mass odnim stepennym pokazatelem okolo -2 (sm. ris. 10 na str. 12). Konechno, otkloneniya est', i zachastuyu oni ochen' veliki. No, povtoryus', na moi vzglyad interesen ne kakoi-to konechnyi vyvod o global'noi funkcii mass, a imenno obzor.

Authors: V. Lipunov, E. Gorbovskoy Comments: 12 pages 3 figures submitted to ApJL Avtory predstavlyayut model' gamma-vspleskov, v kotoryi klyuchevym momentom yavlyaetsya sleduyushee. Pri kollapse bystro vrashayushegosya yadra sperva obrazuetsya spinar - ob'ekt, uderzhivaemyi ot shlopyvaniya centrobezhnymi silami. Na etoi stadii mogut voznikat' ochen' dlinnye plato v krivoi bleska, nablyudaemye i gamma-vspleskov. Potom, kogda spinar dostatochno zamedlitsya, proishodit kollaps v chernuyu dyru. Podrobnee mozhno poslushat' na doklade avtorov 18 maya.
Authors: A.J. Levan et al. Comments: 8 pages, 5 figures, accepted for publication in MNRAS Esli korotko, to avtory polagayut, chto vsplesk mozhet schitat'sya eshe odnim kandidatov v nipervspyshki vnegalakticheskih magnitarov. Reshayushim argumentom sluzhit nalichie v oblasti lokalizacii vspleska otnositel'no blizkoi galaktiki s moshnym zvezdoobrazovaniem IC 328.
Authors: Shai Kaspi Comments: 10 pages, 4 figures, Conference proceedings to appear in "The Central Engine of Active Galactic Nuclei", ed. L. C. Ho and J.-M. Wang (San Francisco: ASP) Chasto sprashivayut: "A kak opredelyayut massy chernyh dyr v galaktikah?" A vot tak! Chitaite ob odnom iz metodov. Ideya sostoit v tom, chto po izmeneniyam potoka izlucheniya ot aktivnogo yadra mozhno sudit' o povedenii gaza vokrug chernoi dyry. Nuzhno tol'ko dostatochno chasto i regulyarno provodit' fotometricheskie nablyudeniya i poluchat' spektry (vazhno ved' takzhe i to, kak menyaetsya intesivnost' spektral'nyh linii i tp.). Nu a povedenie gaza soderzhit v sebe informaciyu o masse dyry. Konechno, metod bolee chem ne pryamoi. Tem ne menee, vpolne poleznyi.
Authors: Virginia Trimble, Markus J. Aschwanden, Carl J. Hansen Comments: 244 pages, no figures Kak izvestno, kniga bez kartinok, ili hotya by bez razgovorov - kniga neinteresnaya. Kartinok net, zato razgovorov!!!! V obshem, vstrechaite! Ocherednoi ezhegodnyi obzor Virdzhinii Trimbl!

Authors: Joergen Knoedlseder Comments: 8 pages, Proceedings of the 6th INTEGRAL Workshop: The Obscured Universe Konechno, "risoval'shik" - eto ne vpolne adekvatnyi perevod slova "imager", no chto delat'!?! Ideya sostoit v tom, chto sovremennye tehnologie pozvolyayut sozdat' gamma-detektor, kotoryi budet dostatochno horosho stroit' izobrazheniya v gamma-dipazone. T.e., eto budet v samom dele gamma-teleskop, rabotayushii napryamuyu s gamma-fotonami. Seichas izobrazheniya v gamma-diapazone stroyatsya primitivno po dannym o prohozhdenii fotona cherez stopku detektiruyushih plastin (na sputnikah), ili zhe nablyudayutsya opticheskie kvanty, porozhdennye vzaimodeistviem gamma-kvantov s atmosferoi (na ustanovkah tipa H.E.S.S.). Avtor opisyvaet proekt sputnika, kotoryi mog by stat' pervym "gamma-risoval'shikom".
Authors: Gregory Gabadadze Comments: 17 pages; based on Carg\se lectures of 2006; to appear in proceedings Oblast', kotoroi posvyashen obzor, na moi vzglyad dostatochno slozhna. S drugoi storony, avtoru udalos' napisat' tekst, dostupnyi bolee-menee lyubomu studentu-fiziku. Esli formuly na urovne ser'eznyh obshih kursov fiziki i matematiki vas ne smushayut, to est' shans razobrat'sya v dovol'no interesnoi teme. Otmechu takzhe eshe odin obzor, posvyashennyi leptogenezisu.
Authors: R. Dib, V. M. Kaspi, F. P. Gavriil. Comments: 28 pages, 8 figures, accepted by ApJ V moih obzorah davno zameten perekos v storonu moih sobstvennyh interesov v astrofizike. Poetomu ne udivlyaites' bol'shomu kolichestvu ssylok na stat'i po neitronnym zvezdam. Vot ocherednaya. Avtory predstavlyayut rezul'taty mnogoletnego monitoringa odnogo iz kandidatov v magnitary. S odnoi storony, nikakih superotkrytii net. S drugoi, dannye stavyat interesnye voprosy pered standartnoi magnitarnoi teoriei.
Authors:M.J. Jee, et al. Comments: To appear in the June 1 issue of The Astrophysical Journal. Po novostyam prokatilos' soobshenie ob obnaruzhenii kol'ca iz temnoi materii. A vot i original'naya stat'ya. Otmechu, chto neskol'ko dnei nazad poyavilos' drugoe pohozhee soobshenie arxiv:0705.1720. Tam rech' shla o razdelenii vidimogo i temnogo veshestva v gravitacionnoi linze. Linza predstavlyaet soboi kol'co einshteina.
Authors: Hagai Netzer, Joseph C. Shields Comments: 12 pages, Conference proceedings to appear in "The Central Engine of Active Galactic Nuclei", ed. L. C. Ho and J.-M. Wang (San Francisco: ASP) Vsego na 12 stranicah avtory popytalis' dat' osnovnye novosti po issledovaniyu aktivnyh yader galaktik. Neplohaya svodka poslednih rezul'tatov, predstavlyayushih interes.
Authors: Athol J. Kemball Comments: 16 pages, 2 figures, 2 tables: based on a review talk presented at IAU Symposium 242: Astrophysical masers and their environments, held at Alice Springs (Australia), March 12-16, 2007 Na moi vzglyad, tema zvezdnyh mazerov yavlyaetsya slegka "nedopopulyarizirovannoi". Pravda, dannyi obzor tut ne ochen' bol'shaya podmoga, ibo napisan on dlya teh, kto vsyu osnovu i tak uzhe znaet - t.e. dlya specialistov.

Authors: Tiziana Di Matteo et al. Comments: 22 pages, 17 figures, submitted to ApJ Rassmatrivaetsya sovmestnaya evolyuciya galaktik i sverhmassivnyh chernyh dyr v ramkah standartnoi ierarhicheskoi modeli. Unikal'nost' chislennoi modeli sostoit v tom, chto vse-vse-vse po vozmozhnosti rassmotreno sovmestno.Vrode by, vse osnovnye zakonomernosti i nablyudatel'nye fakty nahodyat svoe mesto v dannoi modeli.

Authors: A.A. Mikhailov Comments: 4 pages, 4 figures, PDF, a contributed paper presented to 30-th ICRC, Merida, Nexico, 2007 Hotya stat'ya napisana zhutkim yazykom (ne mogu skazat', chto "angliiskim") v nei predstavlena interesnaya, no ochen' spornaya, tochka zreniya. Ona svoditsya k tomu, chto kosmicheskie luchi sverhvysokih energii mogut imet' (po krainei mere chastichno) galakticheskoe proishozhdenie i yavlyayutsya tyazhelymi yadrami.
Authors: D. Berge Comments: 13 pages, 10 figures, based on a talk presented at the workshop 'Energy Budget in the High Energy Universe', Kashiwa, Japan 22 - 24 February 2006 Dan polnyi obzor trehletnih nablyudenii galakticheskih istochnikov na H.E.S.S. Poskol'ku, schitaya etot proekt chrezvychaino vazhnym, ya staralsya regulyarno soobshat' ob ih tekushih rezul'tatah, no raspisyvat' vse v detalyah ne budu (napomnyu tol'ko ob otkrytii 14 novyh galakticheskih istochnikov). No zhelayushie mogut v kompaktnom obzore oznakomitsya so vsemi rezul'tatami H.E.S.S. po galakticheskim istochnikam. Hotelos' by v paru takoi zhe obzor i po vnegalaktike. Lishnii raz napomnyu, chto v etom godu sozdateli H.E.S.S. poluchili dekartovskuyu premiyu, s chem ya ih s udovol'stviem eshe raz pozdravlyayu.

To be published in Springer Lecture Notes Ocherednoi bol'shoi obzor po vnutrennemu sostoyaniyu neitronnyh zvezd. Osoboe vnimanie avtory udelyayut ekzoticheskim fazam (kvarkam, giperonam i tp.).
Authors: K. Maeda et al. Comments: 16 pages, 12 figures. Accepted by the Astrophysical Journal Opisany dannye po neobychnoi sverhnovoi tipa Ib. Avtory predlagayut interpretaciyu, soglasno kotoroi imeet mesto dopolnitel'naya zakachka energii blagodarya rabote molodogo magnitara - bystro vrashayusheisya neitronnoi zvezdy s sil'nym magnitnym polem.
Authors: Carme Gallart (for the LCID Team) Comments: 4 pages, 2 figures. To appear in the Proceedings of IAU Symposium 241: "Stellar Populations as Building Blocks of Galaxies", 10-16 December, 2006 at La Palma, Canary Islands, Spain Opisan proekt po izucheniyu zvezdnyh naselenii i istorii zvezdoobrazovaniya v karlikovyh galaktikah Mestnoi gruppy. Eto ochen' vazhno v svyazi s neobhodimost'yu detal'nogo sravneniya chislennyh raschetov v ramkah modelei ierarhicheskogo formirovaniya struktury s dannymi nablyudenii.

Authors: Bertrand Duplantier Comments: 107 pages, 21 figures, expanded and updated version of the article originally published in Einstein, 1905-2005, Poincar\'e Seminar 2005 (Birkh\"auser Verlag, 2006). Journal-ref: Brownian Motion, "Diverse and Undulating'', in "Einstein, 1905-2005". Poincar\'e Seminar 2005, Th. Damour, O. Darrigol, B. Duplantier and V. Rivasseau, Editors, pp. 201-293 (Birkh\"auser Verlag, Basel, 2006) Ogromnaya stat'ya (kniga prakticheski), posvyashennaya brounovskomu dvizheniyu. Slovo "volnistoe" v zagolovke otrazhaet kolebaniya populyarnosti etogo fenomena. Posle desyatiletii otnositel'nogo zabveniya v nashi dni brounovskie chasticy "snova v boyu".
Authors: Abhay Ashtekar Comments: 21 pages, to appear in the Proceedings of the 11th Marcel Grossmann Conference Otlichnyi obzor po teme. Napisano vpolne dostupno. Ne to chtoby sovsem bez slozhnyh formul, no prakticheski bez nih.
Authors: Ryan Barnett, Gil Refael, Mason A. Porter, Hans Peter Buchler Comments: 5 pages Rassmotrena interesnaya situaciya, kogda sosushestvuyut dva kondensata s raznymi massami chastic (naprimer, raznye atomy). Obrazuyutsya dve sistemy vihrei. Eti dve reshetki "sceplyayutsya" - vihri obrazuyut pary. V itoge voznikaet interesnaya situaciya, kogda kondensaty vrashayutsya s raznoi chastotoi (pri ravnoi plotnosti vihrei, chto obespechivaetsya scepleniem, i raznyh massah, my imeem razlichnye chastoty). Dlya menya eto bylo novym fokusom sverhtekuchih zhidkostei.
Authors: Emil T.Akhmedov, Douglas Singleton Comments: 7 pages Avtory pokazyvayut, chto detektory, dvigayushiesya v techenie konechnogo vremeni s postoyayannym uskoreniem, budut "videt'" izluchenie Unru. Dlya sluchaya dvizheniya po okruzhnosti, po mneniyu avtorov, izluchenie Unru sovpadaet s izvestnym (i eksperimental'no proverennym) effektom Sokolova-Ternova.
