To appear in Annual Reviews of Nuclear and Particle Science, Volume 58 Slaboe linzirovanie yavlyaetsya "poleznym" yavleniem, t.k. pomogaet, naprimer, vyyavlyat' raspredelenie massy v skopleniyah galaktik. T.e., ono ispol'zuetsya kosmologami kak instrument. V stat'e daetsya podrobnyi obzor po etoi teme. Opisyvaetsya bazovaya teoriya, rasskazyvaetsya, kak provodyatsya nablyudeniya i ih obrabotka. Nakonec, obsuzhdayutsya slozhnosti, puti ih preodoleniya i budushie proekty. arxiv:0805.0140 Zvezdnaya ekzotika v 47 Tukana (Stellar Exotica in 47 Tucanae) Authors: Christian Knigge et al. Comments: 28 pages, 22 figures, 1 table, accepted for publication in ApJ Avtory podrobno predstavlyayut rezul'taty nablyudeniya skopleniya 47 Tukana, provedennyh v UF diapazone na Habble. Naideno mnogo ekzoticheskih ob'ektov. Tak vpervye obnaruzhena para goluboi brodyaga+belyi karlik, naidena (v dvoinoi sisteme) goryachaya malomassivnaya zvezda (eto, vidimo, "obodrannyi" gigant), a takzhe naiden gelievyi belyi karlik bez millisekundnogo pul'sara v kachestve soseda po dvoinoi. arxiv:0805.0306 Materinskie galaktiki korotkih gamma-vspleskov: svetimosti, metallichnosti i temp zvezdoobrazovaniya (The Host Galaxies of Short-Duration Gamma-Ray Bursts: Luminosities, Metallicities, and Star Formation Rates) Authors: E. Berger Comments: 11 pages, Submitted to ApJ Korotkie gamma-vspleski nablyudayutsya v galaktikah raznyh tipov. Galaktiki s zametnym zvezdoobrazovaniem sostavlyayut bolee 80 procentov. Ostal'noe - ellipticheskie. Esli sravnivat' materinskie galaktiki korotkih i dlinnyh vspleskov, to u vtoryh oni sistematicheski imeyut men'shuyu metallichnost' i bolee vysokii temp zvezdoobrazovaniya. Avtor polagaet, chto eto govorit o raznyh praroditelyah u korotkih i dlinnyh vspleskov. Standartnaya ideya o tom, chto korotkie vspleski svyazany so sliyanimi neitronnyh zvezd ukladyvaetsya v dannye o materinskih galaktikah. arxiv:0805.0307 Razdelenie effektov naglyadnosti i samoreklamy v fenomene zavisimosti citiruemosti ot polozheniya v vypuske arXiv:astro-ph (Disentangling Visibility and Self-Promotion Bias in the arXiv:astro-ph Positional Citation Effect) Authors: J. P. Dietrich Comments: 3 pages, Accepted for publication in PASP V proshloi stat'e avtor pokazal, chto citiruemost' stat'i sil'no zavisit ot togo, na kakom meste ona stoit v ezhednevnom vypuske Arhiva, chem blizhe k nachalu - tem vyshe citiruemost'. Bylo pokazano, chto net chisto geograficheskogo effekta (esli by vse, skazhem, otpravlyali stat'i posle obeda, to amerikanskie byli by blizhe k nachalu). Ostavalos' dve vozmozhnosti. Ili avtory sami stavyat stat'i blizhe k nachalu, znaya, chto eto polezno (t.e. i popadanie v verhnyuyu chast' spiska, i voobshe horoshaya citiruemost' - rezul'tat celenapravlennyh deistvii). Ili eto prosto delo sluchaya, i v citiruemost' vnosit vklad tol'ko effekt popadaniya v verhnyuyu chast' spiska, kotoraya luchshe prosmatrivaetsya chitatelyami. V novoi stat'e avtor pokazyvaet, chto oba effekta vazhny, t.e. zavedomo est' gruppa v srednem bolee vysokocitiruemyh statei, kotorye avtory celenapravlenno stavyat v takoe vremya, chto oni popadut v verhnyuyu chast' spiska. Zamechu, chto dannaya stat'ya vtoraya vo vtornichnom spiske. obzor arxiv:0704.1800 Fenomenologiya s massivnymi neitrino (Phenomenology with Massive Neutrinos) Authors: M.C. Gonzalez-Garcia, Michele Maltoni Comments: 204 pages, 57 figures. All results updated with the new MINOS, KamLAND and Borexino data. Three new sections added: nu magnetic moment, nu decay, two sterile nu's. Many sections and bibliography expanded. Analysis fully updated as of Fall 2007; Journal-ref: Phys. Rept. 460 (2008) 1-129 Avtory sdelali kross-post v astrofizicheskuyu chast' ogromnogo obzora po neitrino, kotoryi v original'nom vide poyavilsya god nazad. Mnogie razdely (osobenno posvyashennye eksperimentam) vpolne dostupny nespecialistam. arxiv:0805.1228 Kandidat v galaktiki s laimanovskim skachkom na z~9 (A Lyman Break Galaxy Candidate at z~9) Authors: Alaina L. Henry et al. Comments: 4 pages, Accepted to ApJ Letters Vozmozhno, otkryta samaya dalekaya galaktika. Po nablyudeniyam na pribore NICMOS na Kosmicheskom teleskope byli otobrany galaktiki, kotorye mogut nahodit'sya na ochen' bol'shih krasnyh smesheniyah (do desyatki). Avtory predstavlyayut dannye po odnomu iz kandidatov, dlya kotorogo byli provedeny nablyudeniya na kosmicheskom infrakrasnom teleskope im. Spitcera. Poluchaetsya, chto galaktika nahoditsya na z~9. Odnako rezul'tat eshe nuzhdaetsya v podtverzhdenii, o chem avtory pishut dazhe v abstrakte. Rezul'tat poluchen ne po otdel'nym spektral'nym liniyam, a po cvetam (dannye Spitcera ukazyvayut na skachok mezhdu 3.6 i 4.5 mikron, chto avtory interpretiruyut kak bal'merovskii skachok).

Eto nazyvayut gravitacionno-volnovoi raketoi. V poslednie gody effekt nachali uchityvat' v modelyah ierarhicheskogo skuchivaniya galaktik. Avtorov interesuet povedenie uzhe sverhmassivnyh chernyh dyr, to, kak oni budut dvigat'sya, akkrecirovat' i tp. s uchetom togo, chto v rezul'tate sliyanii oni poluchayut dostatochno vysokie (sotni km v sek) skorosti. Pri skorosti otdachi 100 km/s chernaya dyra osyadet obratno v centr galaktiki cherez million let (amplituda "bultyhanii" poryadka 30 pk). Chem vyshe skorost' - tem dol'she budet "boltanie" i bol'she amplituda. Interesno, chto velichina poluchennoi skorosti malo vliyaet na nabor massy chernoi dyroi za vremya "bultyhaniya" v galaktike, t.e. do osedaniya v centr (drugoe delo, chto chem vyshe skorost' - tem dol'she "boltaetsya"). K sozhaleniyu, obnaruzhit' chernye dyry, sil'no smeshennye ot centrov galaktik neprosto, t.k. chem bol'she smeshenie, tem koroche aktivnaya faza kvazara. arxiv:0805.1557 GRB 080319B: vidimyi nevooruzhennym glazom zvezdnyi vzryv v dalekoi vselennoi (GRB 080319B: A Naked-Eye Stellar Blast from the Distant Universe) Authors: J. L. Racusin et al. Comments: 43 pages, 18 figures, 3 tables, submitted to Nature May 11, 2008 Raznye gruppy nablyudatelei (i optiki, i rentgenshiki) napisali obshuyu bol'shuyu stat'yu v Nature, posvyashennuyu vsplesku 19 marta, kotoryi v maksimume byl viden nevooruzhennym glazom. Sovmestnyi analiz opticheskih i gamma/rentgenovskih dannyh pokazyvaet, chto myagkoe i zhestkoe izluchenie rozhdayutsya v odnoi oblasti vdali ot central'nogo istochnika (chernoi dyry), no svyazany s raznymi spektral'nymi komponentami. Vse neploho ukladyvaetsya v standartnuyu kartinu vzryva massivnoi zvezdy, kotoraya do vzryva imela sil'nyi zvezdnyi veter, cherez kotoryi i rasprostranyaetsya sil'no relyativistskii dzhet. arxiv:0805.1873 DARWIN: missiya dlya obnaruzheniya vnesolnechnyh planet i poiska zhizni na nih (DARWIN - A Mission to Detect, and Search for Life on, Extrasolar Planets) Authors: C. S. Cockell et al. Comments: 70 pages Podrobno opisyvaetsya sputnik Darwin. Ideya sostoit v poiske sledov zhiznideyatel'nosti v atmosferah malomassivnyh ekzoplanet po nablyudeniyam v infrakrasnom diapazone. Daetsya horoshii obzor vsego, chto svyazano s poiskami zhizni na ekzoplanetah. arxiv:0805.1922 Temp sverhnovyh tipa Ia na z~0.2 po dannym s perekryvayushihsya polei v SDSS-I (The Rate of Type Ia Supernovae at z~0.2 from SDSS-I Overlapping Fields) Authors: Assaf Horesh, Dovi Poznanski, Eran O. Ofek, Dan Maoz Comments: 11 pages, Submitted to MNRAS Poluchena novaya ocenka tempa vspyshek sverhnovyh tipa Ia na nebol'shih krasnyh smesheniyah. Temp primerno 14 10-14 v god na odnu svetimost' Solnca (esli interesny oshibki i normirovki - smotrite original stat'i). Ocenka primerno sovpadaet s bolee rannimi. Avtory polagayut, chto stoit eshe ryt'sya v dannyh SDSS-I, tk. tam eshe mnogo sverhnovyh ne vyyavleno. obzor arxiv:0805.2082 Vvedenie v chernye dyry (Introduction to black holes) Authors: Gustavo E. Romero Comments: 25 pages, 6 figures, Lecture Notes from the First La Plata International School on Astronomy and Geophysics Nichego osobennogo - prosto horoshii ocherednoi obzor po chernym dyram. Rech' tam idet ne o nablyudeniyah, a o fizike. Kakie-to voprosmy lish' melkom upomyanuty, a kakie-to razobrany bolee detal'no.

Esposito Comments: Latex, amsart, 7 pages, 2 (low resolution) eps figures Korotkaya istoricheskaya zametka. Avtor obsuzhdaet nedavno obnaruzhennyi v arhive Chedvika konspekt lekcii Fermi, kotorye tot chital v Los Alamose posle voiny. Avtor polagaet, chto dannyi konspekt ukazyvaet na to, chto lekcii Fermi okazali vliyanie na razvitie britanskogo atomnogo proekta, tak kak v techenie nekotorogo vremeni im prihodilos' dvigat'sya vpered bez sushestvennoi pomoshi s amerikanskoi storony. Krome togo, obnaruzhennyi konspekt interesen i sam po sebe, tak kak soderzhit nekotorye materialy, ne vhodivshie v izvestnye versii konspektov. arxiv:0805.0289 Stepeni svobody, svyazannye s cvetom, v fizike elementarnyh chastic (The color charge degree of freedom in particle physics) Authors: O.W.
