Reynolds et al. Comments: 4 pages, 2 figures, submitted to ApJL Ya podrobno rasskazyval ob otkrytii novogo tipa neitronnyh zvezd (sm. zdes' i zdes'). I vot - novaya novost'. Odin iz novyh istochnikov sluchaino popal v pole zreniya Chandry vesnoi etogo goda. Analiz pokazal nalichie rentgenovskogo istochnika. T.k. Chandra daet dostatochno tochnye koordinaty, to udalos' pokazat', chto ni v optike, ni v IK tam nichego ne vidno. Eto podtverzhdaet gipotezu o tom, chto my imeem delo s odinochnoi neitronnoi zvezdoi. Mne lichno takzhe ochen' radostno, chto novye dannye sovmestimy s gipotezoi o teplovom izluchenii neitronnoi zvezdy. Togda, v samom dele, eto mogut byt' ob'ekty tipa Velikolepnoi semerki. miniobzor astro-ph/0512384 Obrazovanie galaktik (Galaxy Formation) Authors: Eric Gawiser Comments: Invited review to appear in New Horizons in Astronomy, ASP Conference Series (13 pages) V obzore summirovanny dannye po obrazovaniyu galaktik. Podcherknu, chto rech' idet imenno o dannyh, t.e. o nablyudeniyah ob'ektov na bol'shih krasnyh smesheniyah i t.p. astro-ph/0512398 EMMA - novyi podzemnyi eksperiment po kosmicheskim lucham (EMMA - A New Underground Cosmic-Ray Experiment) Authors: T.

Preprint not submitted V Finlyandii stroitsya novyi eksperiment po issledovaniyu kosmicheskih luchei. Eto budet bol'shoi detektor, ustanovlennoi v shahte. Osnovnaya cel' - issledovanie sostava kosmicheskih luchei v oblasti "kolena" (eto vazhnaya detal' v raspredelenii kosmicheskih luchei po energiyam, veroyatno, chto chasticy s energiyami vyshe i nizhe kolena imeyut raznoe proishozhdenie).

Winter et al. Comments: 51 pages, submitted to ApJ (March 2005) Issledovany okolo 100 ul'tramoshnyh istochnikov (UMI) v 32 blizkih galaktikah. Eto udalos' sdelat', ispol'zuya dannye uzhe ochen' bol'shogo arhiva, nakoplennogo pri nablyudeniyah na sputnike XMM-Newton. Cel'yu bylo issledovanie voprosa o sushestvovanii chernyh dyr promezhutochnyh mass. Pohozhe, chto klass UMI vse-taki ne odnoroden. Nesmotrya na to, chto chast' iz soavtorov stat'i priderzhivaetsya gipotezy o chernyh dyrah promezhutochnyh mass, v stat'e pishetsya o mnogochislennyh istochnikah, kotorye, po vsei vidimosti, yavlyayutsya obychnymi chernymi dyrami (t.e. imeyushimi zvezdnye masssy). Lish' nebol'shaya dolya (16 istochnikov) veroyatno yavlyayutsya sistemami s massivnymi chernymi dyrami. Tem ne menee, i etu dolyu kak-to nado ob'yasnyat'. gr-qc/0507079 Prohodimost' chervotochiny Einshteina-Rozena za schet ispareniya (Evaporation induced traversability of the Einstein--Rosen wormhole) Authors: S. Krasnikov Comments: v.2 A bit of discussion has been added and a few references Krasnikov - odin iz samyh kompetentnyh specialistov po resheniyam v OTO, v kotoryh vozmozhno sushestvovanie mashiny vremeni. Eta stat'ya takzhe posvyashena peremesheniyu po chervotochinam. Pokazano, chto, esli s samogo nachala vo Vselennoi est' chervotochina, kotoraya isparyaetsya, to mozhno tak podobrat' parametry, chto vozniknet reshenie, v kotorom vozmozhna mashina vremeni. Razumeetsya, eto skoree matematicheskii rezul'tat, i govorit' o tom, chto okonchatel'no naiden put', kotoryi mozhet privodit' k puteshestviyam vo vremeni, ne prihoditsya. Tem ne menee .... hep-ph/0512187 Prosveshenie, znanie, nevezhestvo, iskushenie (Enlightenment, Knowledge, Ignorance, Temptation) Authors: Frank Wilczek Comments: 10 pages, 5 figures. Summary talk at ``Expectations of a Final Theory'', Trinity College, Cambridge, September 2005. v2: date of earlier conference corrected (2003->2001) Frank Vil'chek chasto vystupaet s interesnymi dokladami na "obshie temy".

Vsyacheski sovetuyu. astro-ph/0512515 Razmer v 1 a.e. dlya radioistochnika Sgr A* v centre nashei Galaktiki (A size of ~1 AU for the radio source Sgr A* at the centre of the Milky Way) Authors: Zhi-Qiang Shen, K. Y. Lo, M.-C. Liang, Paul T. P. Ho, J.-H. Zhao Comments: 18 pages, 4 figures; Nature, 438(2005)62 Etot rezul'tat poluchil bol'shoi rezonans v novostyah, poetomu upominaem o nem. Hotya, nichego supernovogo po suti ne otkryto. Avtoram udalos' sdelat' vazhnuyu, no dostatochno tehnicheskuyu vesh'. Oni vdvoe smogli uluchshit' predel na razmer istochnika v centre nashei Galaktiki. Dostignutoi znachenie v 1 a.e. pozvolyaet s bol'shei uverennost'yu govorit' ob interpretacii istochnika kak sverhmassivnoi chernoi dyry. astro-ph/0512556 Rentgenovskie i opticheskie svoistva novyh ob'ektov tipa gamma Kassiopei, obnaruzhennyh v rentgenovskih obzorah (X-ray and optical properties of new Gamma Cas-like objects discovered in X-ray surveys) Authors: Christian Motch, et al. Comments: 7 pages, to appear in "Active OB Stars: Laboratories for Stellar & Circumstellar Physics", eds. S. Stefl, S. P. Owocki & A. Okazaki. ASP Conf. Ser. 2006, in press (uses asp style) Gamma Kassiopei - izvestnaya yarkaya zvezda tipa Ve. T.e. eto massivnaya zvezda klassa V s emissionnymi liniyami v spektre. U nee obnaruzhen izbytok rentgenovskogo izlucheniya. Prichina mozhet byt' v nalichii kompan'ona, na kotoryi idet akkreciya. Samo po sebe eto ne udivitel'no, rentgenovskie sistemy s Ve-zvezdami sostavlyayut 2/3 vseh massivnyh rengenovskih dvoinyh (sm. katalog v astro-ph/0505275, setevaya versiya kataloga gotovitsya Natal'ei Raguzovoi). Odnako, esli vse eti sistemy sostoyat iz Ve-zvezdy i neitronnoi zvezdy, to gamma Kassiopei - yavno net. Vozmozhno, chto ee kompan'onom yavlyaetsya belyi karlik (ne isklyucheno i to, chto veter zvezdy imeet interesnye svoistva, privodyashie k izbytku rentgenovskogo izlucheniya; prichina mozhet kryt'sya v diske, sushestvuyushem vokrug bystro vrashayusheisya zvezdy). Gamma Kassiopei - yarkii blizkii istochnik. Teper' s razvitiem tehniki rentgenovskih nablyudenii, nachali otkryvat' mnozhestvo istochnikov, pohozhih po svoim svoistvam na etu zvezdu. Sobstvenno, etomu i posvyashena stat'ya. Bolee detal'nye rezul'taty budut vskore predstavleny v polnoi zhurnal'noi publikacii, kotoraya, naskol'ko mne izvestno, uzhe prinyata v pechat'.
