Authors: Piero Madau Comments: 6 pages, 1 figure, Nature News and Views on Aharonian et al. 2006, Nature, 440, 1018-1021. Journal-ref: Nature 440 (2006), 1002-1003 Eto ne original'naya stat'ya, a dovol'no interesnoe esse iz razryada teh, chto tak lyubyat publikovat' v Nature. Posvyasheno ono tomu, chto nablyudateli do sih por ne mogut dat' chetkogo otveta o tom, kak svetili samye pervye zvezdy.
Authors: The IceCube Collaboration IceCube - gigantskii neitrinnyi detektor v Antarktide. Yasno, chto takie pribory ne sozdayutsya za den'. Postepenno v led budut vmorazhivat'sya niti s detektorami. Pervye uzhe "na meste" i rabotayut. Analizu pervyh dannyh s uzhe rabotayushei chasti detektora i posvyashena stat'ya. Rezul'taty poka skoree tehnicheskie chem nauchnye. Vyvod: vse rabotaet kak nado.
Authors: Kajal K. Ghosh et al. Comments: 7 pages, submitted to ApJ Obnaruzhena dovol'no interesnaya rentgenovskaya sistema. Prelest' poka v tom, chto ob'yasnit' ee mozhno s pomosh'yu celogo nabora variantov.
Authors: S. C. Wolff, S. E. Strom, D. Dror, L. Lanz, K. Venn Comments: 19 pages, two tables, 2 figures Avtory privodyat bol'shoe kolichestvo dannyh po vrasheniyu molodyh zvezd raznyh mass (ot 0.2 do 50 mass Solnca). Osnovnoi vopros, kotoryi zadavali sebe avtory takov: mozhno li po dannym o vrashenii sdelat' vyvod o tom, obrazuyutsya li zvezdy raznyh mass podobnym obrazom, ili zhe massivnye i malomassivnye poyavlyayutsya na svet po-raznomu. Osnovnoi vyvod: vrashatel'nye svoistva ne soderzhat nikakogo skachka pri uvelichenii massy. T.o., polagayut avtory, dolzhen sushestvovat' edinyi mehanizm, otvetstvennyi za poyavlenie zvezd raznyh mass.

Authors: Jiri Bicak Comments: 8 pages, published in Encyclopedia of Mathematical Physics, eds. J.-P. Francoise, G. L. Naber and Tsou S. T., Oxford: Elsevier, 2006 (ISBN 978-0-1251-2666-3), volume 2, page 165-173. (The number of references had to be limited, some additional references are indicated inside the text only.) Obratite vnimanie, eto stat'ya dlya enciklopedii matematicheskoi fiziki.
Authors: Volker Springel et al. Comments: Invited review to Nature , 2006, 440, 1137 Obzor po krupnomasshtabnoi strukture. My privykli, chto esli Nature - to obzor korotkii, no tut drugoe delo. 34 stranicy.
Authors: Roland Oechslin, Thomas Janka Comments: 6 pages, 2 figures, Proceedings of the Albert Einstein Century International Conference, Paris, France, 2005, edited by Jean-Michel Alimi and Andre Fuzfa Modelirovat' sliyaniya neitronnyh zvezd voobshe slozhno. Esli zhe v dobavok interesuet, kak vse eto budet svetit' v gamma-diapazone, to zadacha stanovitsya eshe slozhnee. Na moi vzglyad, poka programmy nedostatochno sovershenny, chtoby davat' chetkie detal'nye odnoznachnye otvety, no progress nalico.
Authors: Colin J. Lonsdale et al. Comments: 24 pages, 3 figures, 1 table. Accepted for publication in Ap.J Arp 220 - odna iz t.n. "fabrik sverhnovyh". Eto galaktika s moshneishim zvezdoobrazovaniem. Avtory privodyat dannye radionablyudenii pochti 5 desyatkov radiosverhnovyh. Poluchennye rezul'taty svidetel'stvuyut o tempe vspyshek v yadre (!) Arp 220 ravnom 4 sverhnovye v god.
Authors: Yael Naze Comments: review published by the Liege Royal Societey of Sciences, 31 pages without figures; Journal-ref: Bull.Soc.Roy.Sci.Liege 75 (2006) 20-61 Poleznyi obzor.
Authors: D. A. Frail et al. Comments: Submitted to ApJ(Letters) Obnaruzheno poslesvechenie v radiodiapazone ot gamma-vspleska GRB 050904, vspyhnuvshego na krasnom smeshenii z=6.3.
Authors: M. Kramer et al. Comments: 12 pages, 2 figures; Science 312 (2006) 549-551 Pul'sar PSR B1931+24 (J1933+2421) obladaet interesnym povedeniem: v techenie neskol'kih dnei on svetit kak obychnyi pul'sar, a potom na neskol'ko nedel' vyklyuchaetsya. Kogda on nahoditsya v aktivnom sostoyanii, to temp ego zamedleniya v dva raza vyshe, chem kogda on vyklyuchen. Iz razgovorov so specialistami ya ponyal, chto oni vozlagayut bol'shie nadezhdy na etot pul'sar. Veroyatnee vsego on mozhet sygrat' rol' rozetskogo kamnya. Imeya dannye o tempe zamedleniya v aktivnom i passivnom sostoyaniyah, my mozhem sudit' o tokah, tekushih v magnitosfere pul'sara, chto yavlyaetsya kriticheskim voprosom dlya konkuriruyushih teorii pul'sarnyh magnitosfer. Ili, mozhno skazat', chto etot pul'sar stanet lakmusovoi bumazhkoi. Ibo v nekotoryh teoriyah opisat' takoe povedenie mozhno, a v nekotoryh - nel'zya.

Authors: M. Fellhauer et al. Comments: ApJ (Letters), submitted Dobavlyu, chto dannye o forme galo vazhny, kak eto ne stranno, i dlya fiziki elementarnyh chastic. Delo v tom, chto ryad avtorov pytaetsya ob'yasnit' izbytok gamma-luchei, nablyudavshiisya priborom EGRET, kak izluchenie temnoi materii v galo nashei galaktiki. Izluchenie voznikaet blagodarya raspadu chastic temnoi materii. Novye dannye o forme galo dolzhny pomoch' utochnit' modeli gamma-izlucheniya. T.o., vozmozhno, mozhno budet poluchit' dannye o supersimmetrii ne iz uskoritel'nyh eksperimentov, a iz astrofizicheskih dannyh.
Authors: Sean N. Raymond Comments: Accepted by ApJ Letters Privodyatsya rezul'taty chislennogo modelirovaniya obrazovaniya planet tipa Zemli v sistemah s planetami-gigantami na raznyh orbitah. Pokazano, chto esli orbita planety-giganta prohodit blizhe 3.5 a.e., to obrazovanie zemnopodobnoi planety nevozmozhno. Takzhe problemy voznikayut, esli planeta-gigant imeet bol'shoi ekscentrisitet orbity. Po suti eto oznachaet, chto podavlyayushee bol'shinstvo izvestnyh ekzoplanetnyh sistem ne mozhet soderzhat' planety tipa Zemli. Ot sebya zamechu, chto dlya zhizni mozhet naitis' mesta na sputnikah planet-gigantov.
Authors: S. A. Petrova Comments: 8 pages, 2 figures. Invited review for the 2005 Hanas Lake International Pulsar Symposium, to appear in ChJAA Kak izvestno, u pul'sarov, krome obychnyh, nablyudayutsya eshe i t.n. gigantskie impul'sy. Proishozhdenie etogo fenomena neyasno. V stat'e privoditsya odna iz gipotez, ob'yasnyayushaya gigantskie impul'sy.
Authors: Rene A. Ong Comments: 29 pages, 9 figures, Rapporteur Talk at ICRC 2005 V poslednee vremya nazemnaya gamma-astronomiya, rabotayushaya v diapazone energii horosho za 1 GeV, perezhivaet period burnogo razvitiya. Osnovnye vehi etogo bol'shogo puti i sovremennoe sostoyanie del otrazheny v nebol'shom obzore.
Authors: P. Meszaros Comments: To appear in Reports on Progress in Physics, 74 pages, 11 figures, uses iopart.cls macros; updated references Bol'shoi obzor po gamma-vspleskam. Nablyudenii vse bol'she, v kosmologicheskoi prirode nikto ne somnevaetsya, a vot yasnosti s "central'noi mashinoi" vse net.
Authors: V. Avila-Reese Comments: 50 pages, 10 low-resolution figures. Lectures given at the IV Mexican School of Astrophysics, July 18-25, 2005 (submitted to the Editors on March 15, 2006) V obzore podrobno (i ponyatno) rassmotren process formirovaniya galaktik.
Authors: Alexander Vilenkin Comments: 4 pages, no figures; invited "perspective" article in "Science" (4 May 2006) Vopros ob ob'yasnenii velichiny kosmologicheskoi postoyannoi trevozhit uchenyh. Dlya mnogih vedushih fizikov-teoretikov eto vopros nomer odin. Dannaya korotkaya zametka posvyashena kriticheskomu analizu idei Shteinharda i Turoka, a takzhe antropnomu razresheniyu voprosa.
Authors: Jian Ge et al. Comments: 42 pages, 11 figures and 5 tables, Accepted for publication in ApJ Vazhno ne to, chto otkryta eshe odna ekzoplaneta, a to, chto zarabotal eshe odin pribor, prednaznachennyi dlya ih poiska.
Authors: Martin Durant, Marten H. van Kerkwijk Comments: 19 pages AASTEX, 4 figure. Accepted for publication in ApJ. Proveden novyi analiz infrakrasnyh dannyh po odnomu iz anomal'nyh rentgenovskih pul'sarov. Vidimo, ob'ekt, kotoryi ran'she schitalsya infrakrasnym istochnikom, svyazannym s magnitarom, takovym ne yavlyaetsya.
Authors: Matthew D. Duez et al. Comments: 27 pages, 30 figures; Journal-ref: Phys. Rev. D73 (2006) 104015 Privodyatsya rezul'taty chislennogo modelirovaniya povedeniya molodyh neitronnyh zvezd s uchetom mnogih detalei.
Authors: Lawrence M. Krauss Comments: 10 pages. Invited review lecture, International Workshop on NO-VE, Venice, 2006 Poskol'ku seichas standartnaya model' eto "lyambda-SiDiEm", t.e. holodnaya temnaya materiya s kosmologicheskoi postoyannoi, to o neitrino kosmologi kak-to stali zabyvat'. V obzore opisyvaetsya pochemu eto vse-taki ne stoit delat'.
Authors: G. Valyavin et al. Comments: accepted for publication in the Astrphysical Journal Pryamye opredeleniya magnitnyh polei u belyh karlikov - vazhnaya zadacha. Yasno, chto chem men'she polya, tem slozhnee ih obnaruzhit'. Polya poryadka MegaGaussa harakterny lish' dlya maloi doli karlikov. A vot kilogaussovye polya tipichny uzhe dlya 25 procentov etih kompaktnyh zvezd. (Pol'zuyas' sluchaem, hochu anonsirovat' svoyu stat'yu v iyul'skom nomere "Vokrug sveta", gde budet i pro belye karliki).
Authors: P. R. McCullough et al. Comments: 31 pages, 9 figures, accepted for part 1 of ApJ Naidena tranzitnaya planeta u zvezdy tipa Solnca. Planeta - dovol'no tipichnyi goryachii Yupiter. Esli by u nas byl takoi zhe, to nas by tut ne bylo.
Authors: R. Krivonos et al. Comments: 13 pages, 19 figures, submitted to Astronomy and Astrophysics Privodyatsya dannye observatorii INTEGRAL. Kto eshe ne uspel uznat', chto takoe galactic ridge - chitaite i privykaite k novomu (otnositel'no) terminu.
Authors: Yuki Kaneko et al. Comments: 90 pages including 38 figures and 15 tables. Accepted for publication in ApJ Supplement. Two machine-readable tables are included in the source files. The actual spectral catalog will soon be available through HEASARC Browse BATSE potop, no delo ego zhivet! Prodolzhaetsya rabota s dannymi BATSE po gamma-vspleskam. Priyatno, chto rebyata prodolzhayut rabotat', prichem vykladyvayut dannye v otkrytyi dostup v udobnom dlya pol'zovatelei vide.
Authors: Fernando Camilo et al. Comments: 6 pages, 2 figures. Submitted to Nature Otkryto pul'siruyushee radioizluchenie ot odnogo iz anomal'nyh rentgenovskih pul'sarov. Esli ranee lish' Pushinskim gruppam udavalos' uvidet' radioizluchenie ot t.n. radiotihih neitronnyh zvezd (anomal'nye rentgenovskie pul'sary, istochniki myagkih povtoryayushihsya gamma-vspleskov, Velikolepnaya semerka) v nizkochastotnom diapazone, to teper' i v standartnom pul'sarnom diapazone udalos' koe-chto razglyadet'!
Authors: A.D. Kaminker et al. Comments: 8 pages, 5 figures, submitted to MNRAS Izuchaetsya teplovaya evolyuciya magnitarov. Avtory polagayut, chto u magnitarov dolzhen byt' kakoi-to istochnik dopolnitel'nogo podogreva vo vneshnih sloyah.
Authors: K. S. Noll, H. F. Levison, W. M. Grundy, D. C. Stephens Comments: 20 pages, 4 figures, 1 table accepted for publication in Icarus Po nablyudeniyam na Kosmicheskom teleskope otkryt kompan'on u odnogo iz kentavrov - ob'ekta (42355) 2002 CR46. Iz vos'mi ob'ektov, nablyudavshihsya na Habble, eto pervyi s kompan'onom.
Authors: Douglas Scott, J.P. Zibin Comments: 6 pages, 1 figure Dannye nablyudenii govoryat o tom, chto krivizna nashei vselennoi mala. Eto oznachaet, chto za nashim gorizontom chastic vse ne zakanchivaetsya i, bolee togo, "vneshnii" ob'em prevoshodit "vnutrennii". Mozhno, osnovyvayas' na nablyudatel'nyh dannyh (prezhde vsego rech' idet o nablyudeniyah reliktovogo fona, t.e. o dannyh WMAP), dat' nizhnii predel na "vneshnii" ob'em. S uchetom neopredelennostei sovremennyh dannyh "vneshnii" ob'em prevoshodit "vnutrennii" kak minimum na poryadok.
Authors: Tristan Guillot et al. Comments: Astronomy and Astrophysics (2006) in press Pokazano, chto metallichnost' zvezdy igraet bol'shuyu rol' v tom, budut li u nee planety.
My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing).
Authors: M. G. Banks Comments: To appear in Scientometrics, 4 pages Yasno, chto citirovanie zavisit ot oblasti issledovanii. Avtor rassmatrivaet, kak dannye po citirovaniyu mogut byt' ispol'zovany dlya opredeleniya (kolichestvennogo) togo, kakie oblasti seichas yavlyayutsya "goryachimi".

Roehner Comments: 13 pages, 6 figures To appear in the Journal of Economic Interaction and Coordination Dlya razdela physics sociotematika davno uzhe stala standartnoi. V dannoi stat'e rassmatrivaetsya dinamika razlichnyh etnicheskih grupp v krupnyh amerikanskih gorodah, v chastnosti problema massovoi migracii belogo naseleniya iz ryada krupnyh gorodov.
Authors: Joao E. Steiner Comments: 15 pages, 1 figure, 6 tables Avtor rassmotrel s pomosh'yu kakih kriteriev mozhno vystroit' razumnyi reiting universitetov. Predlagaetsya ispol'zovat' tri: nauchnye rezul'taty (skladyvaetsya iz chisla publikacii v Nature i Science i iz chisla uchenyh s vysokim indeksom citirovaniya), stepen' otkrytosti ili "internacionalizm" (skladyvaetsya iz chisla inostrannyh studentov i prepodavatelei), i otnoshenie chisla sotrudnikov k chislu studentov. Rezul'tat ne bleshet osoboi noviznoi ili original'nost'yu. Sushestvenno to, chto pri sostavlenii reitinga ne stoit ispol'zovat' sil'no korrelirovannye drug s drugom parametry, a naoborot, sleduet brat' te, kotorye drug s drugom korreliruyut slabo ili antikorreliruyut.
