H. Chung et al. Comments: 38 pages, 9 figures Avtory detal'no rassmatrivayut, kak dannye s novyh uskoritelei smogut byt' ispol'zovany dlya proverki teorii temnoi energii i temnogo veshestva.

Semikoz, for the Pierre Auger Collaboration Comments: 4 pages, Contribution to the 30th International Cosmic Ray Conference, Merida, Mexico, July 2007 Top-daun (top-down) - eto modeli, v kotoryh chasticy kosmicheskih luchei priobretayut svoi energii ne v rezul'tate razgona v kakom-to kosmicheskom uskoritele, a obrazuyutsya v rezul'tate raspadov massivnyh chastic. Novye dannye, poluchennye s pomosh'yu observatorii imeni P'era Ozhe, pozvolyayut nalozhit' sushestvennye ogranicheniya na eti modeli.

Mark yavlyaetsya specialistom po reliktovomu izlucheniyu, poetomu ne udivitel'no, chto znachitel'naya chast' obzora tak ili inache svyazana s etoi temoi. Podrobno ob'yasnyaetsya mnogo momentov, osobenno svyazannyh s polyarizaciei relikta. Takzhe podrobno razbiraetsya vopros o temnom veshestve, rassmatrivayutsya osnovnye gipotezy. Zatem, sleduya zagolovku (v kotorom, zamechu, relikta-to ne bylo:) ), avtor perehodit k temnoi energii. Zdes' bol'she privodyatsya dannye nablyudenii, chem razbiraetsya teoriya. Obzor okazyvaetsya ne ochen' sbalansirovannym, no, povtoryus', pro reliktovyi fon tam rasskazano ochen' horosho. Krome togo, ostal'nye chasti napisany ochen' yasno, nu i informaciya tam svezhaya.

Story, Peter L. Gonthier, Alice K. Harding Comments: 38 pages, 10 figures, accepted in ApJ Sputnik AGILE uzhe na orbite. GLAST dolzhen poletet' v konce goda. Vse eto gamma-observatorii (tol'ko AGILE- malen'kaya, a GLAST - bol'shaya). Vse pomnyat, chto radiopul'sary i drugie neitronnye zvezdy yavlyayutsya (ili mogut yavlyat'sya) gamma-istochnikami. Eto yavlyaetsya motivirovkoi dlya detal'nogo izucheniya etih ob'ektov metodom populyacionnogo sinteza. Avtory sushestvenno prodivinuli svoyu chislennuyu model'. Osnovnye rezul'taty takovy. 1. V kataloge EGRET est' dostatochnoe kolichestvo neotozhdestvlennyh istochnikov, chast' iz nih, polagayut avtory - eto millisekundnye pul'sary. V dannyh EGRET dolzhno byt' okolo desyatka millisekundnyh radiopul'sarov, a eshe vdobavok okolo dvuh desyatkov millisekundnyh pul'sarov, kotorye ne vidny nam v radio. 2. GLAST konechno zhe uvidit bol'she millisekundnyh pul'sarov. Avtory nazyvayut chislo poryadka 140-150.

Soderberg Comments: 8 pages, Proceedings for "Supernova 1987A: 20 Years After: Supernovae and Gamma-Ray Bursters" AIP, New York, eds. S. Immler, K.W. Weiler, and R. McCray Kak izvestno, dlinnye gamma-vspleski mnogie svyazyvayut so sverhnovymi. Prichem ne so vsyakimi, a tol'ko s tipom Ibc (sm. takzhe arxiv:0706.3209). Prichem, ne vse sverhnovye etogo tipa, a lish' chast'. Vot pro poslednee i idet rech' v stat'e. Avtor pokazyvaet, chto esli gamma-vspleski i rentgenovskie vspyshki zakachivayut v energiyu relyativistskogo potoka veshestva bolee 1048 erg, to sverhnovye Ibc obychno zakachivayut men'she. V itoge, menee 3 proecntov ot blizkih sverhnovyh etogo tipa dayut osnovanie zapodozrit' ih svyaz' s gamma-vspleskami. Razumeetsya, "mnogoe sdelano, no mnogoe eshe predstoit". Avtor nadeetsya, chto planiruemye opticheskie obzory, prednaznachennye dlya poiska sverhnovyh, smogut prolit' svet na fiziku sverhnovyh Ibc, i na i' svyaz' s gamma-vspleskami i rentgenovskimi vspyshkami. arxiv:0706.3048 Temnoe yadro Abel' 520 (A Dark Core in Abell 520) Authors: A. Mahdavi et al. Comments: 10 pages, 5 figures, accepted for publication in the Astrophysical Journal Abel' 520 - eto bogatoe skoplenie galaktik na z=0.201. Po dannym o slabom linzirovanii udalos' postroit' raspredelenie massy. Udivitel'naya osobennost' skopleniya takova: u nego est' massivnoe temnoe yadro. Drugie svoistva ne vyzyvayut udivleniya (t.e. nikakoi superekzotiki, na pervyi vzglyad, net). Yadro sovpadaet s maksimumom rentgenovskogo izlucheniya (za nego otvechaet goryachii gaz), a vot galaktik tam - malo. arxiv:0706.3179 Ostatki sverhnovyh s magnitarami: klyuch k obrazovaniyu magnitarov (Supernova remnants with magnetars: clues to magnetar formation) Authors: Jacco Vink Comments: 9 pages, Accepted by Advances in Space Research (Cospar 2006, Beijing, Session E1.4) Avtor polagaet, chto dannye po ostatkam sverhnovyh, v kotoryh nablyudayutsya kandidaty v magnitary, svidetel'stvuyut protiv togo, chto eti neitronnye zvezdy rozhdayutsya odnovremenno so sverhsil'nymi polyami i ochen' bystrym vrasheniem.

Klypin, F. Prada Comments: 7 pages, 2 figures Poslednie gody idet massirovannaya proverka MOND (modificirovannoi n'yutonovskoi dinamiki) i drugih podobnyh teorii na raznyh astrofizicheskih sistemah. Vse proverki v pol'zu standartnyh teorii. Ne isklyuchenie i novaya rabota. V dannom sluchae po dannym SDSS izuchaetsya dvizhenie sputnikov galaktik.

Bylo vyskazano predpolozhenie, chto eto mozhet byt' svyazano s tem, chto v ellipticheskih galaktikah central'nye sverhmassivnye chernye dyry bystree vrashayutsya. V dannoi stat'e avtory proveryayut etu ideyu. V samom dele, raschety pokazyvayut, chto iz-za togo, chto rost mass chernyh dyr v ellipticheskih galaktikah proishodit vo vremya moshnyh epizodov akkrecii, svyazannyh so sliyaniyami s krupnymi galaktikami, a v diskovyh massa dyr rastet iz-za skromnyh epizodov, vrashenie chernyh dyr bystree v ellipticheskih. arxiv:0706.3940 Severnaya chast' observatorii im.
