Authors: Tod E. Strohmayer, Anna L. Watts Comments: 13 Pages, 5 figures, AASTeX, accepted for publication in the Astrophysical Journal Letters Ochen' vazhnoe otkrytie, dopolnyayushee analogichnoe obnaruzhenie oscillyacii u drugogo istochnika myagkih povtoryayushihsya gamma-vspleskov SGR 1806-20 vo vremya dekabr'skoi vspyshki 2004 goda, sdelannoe Nandoi Rea (Nanda Rea) s kollegami. V hvoste gigantskoi vspyshki obnaruzheny kvaziperiodicheskie kolebaniya s chastotoi 84 gerca. Eti kolebaniya svyazyvayut s torsionnymi kolebaniyami neitronnyh zvezd. Oba rezul'tata (i po SGR 1806-20, i po SGR 1900+14) byli predmetami interesnyh diskussii na nedavnei konferencii po neitronnym zvezdam v Vankuvere.
Authors: M.G.F. Kirsch et al. Comments: 12 pages, 7 figures Krab (i pul'sar, i tumannost') s davnih por yavlyaetsya standartnym istochnikom dlya kalibrovki rentgenovskih sputnikov. Sootvetstvenno, est' ogromnoe kolichestvo dannyh. Avtor opisyvaet poslednie dannye s HMM-N'yuton i sravnivaet ih s massivom rannih rezul'tatov s raznyh sputnikov.
Authors: M.G.F. Kirsch et al. Comments: 12 pages, 16 figures, SPIE paper number 5898-29 V dekabre 2004 HMM-N'yuton otmetil 5-letie s momenta zapuska. Razumeetsya, s samogo nachala raboty vsya apparatura nahoditsya pod pristal'nym vnimaniem specialistov. V stat'e opisyvaetsya kachestvo raboty vseh instrumentov na protyazhenii proshedshih pyati let.
Authors: Karl Gebhardt, R. Michael Rich, Luis C. Ho Comments: accepted for publication in the Astrophysical Journal Rezul'taty novyh nablyudenii vkupe s novym modelirovaniem pozvolili avtoram dat' ocenku massy chernoi dyry v sharovom skoplenii G1: 13000-23000 massy solnca. Veroyatnost' togo, chto chernoi dyry net sostavlyaet menee 3 procentov.
Authors: Scott D. Hyman et al. Comments: 16 pages including 4 figures. Submitted to The Astrophysical Journal Ranee ya uzhe rasskazyval ob otkrytii udivitel'nogo istochnika GCRT J1745-3009. V novoi stat'e avtory opisyvayut registraciyu etogo zagadochnogo ob'ekta v radiodiapazone v 2003 godu. V 2003 g. istochnik byl v neskol'ko raz slabee, chem v 2002 g. Po vsei vidimosti v 2003 byl zaregistrirovan vsego odin vsplesk. Priroda istochnika po-prezhnemu ostaetsya neponyatoi.

Authors: H.E.S.S. Collaboration: F. Aharonian, et al Comments: 9 pages, 3 figures, Science 309, 746 (2005) S pomosh'yu ochen' uspeshno rabotayushei ustanovki H.E.S.S. udalos' zaregistrirovat' izluchenie ot odnogo iz mikrokvazarov LS 5039. Eto, v principe, ozhidaemyi rezul'tat, t.k., esli takoe izluchenie nablyudaetsya ot aktivnyh yader galaktik s dzhetami, a mikrokvazary yavlyayutsya ih umen'shennoi (i blizkoi k nam) kopiei, to razumno predpolozhit' vozmozhnost' registracii gamma-luchei vysokih energii i ot mikrokvazarov.
Authors: Mark L. McConnell et al. Comments: 12 pages; conference paper presented at the SPIE conference "UV, X-Ray, and Gamma-Ray Space Instrumentation for Astronomy XIV." To be published in SPIE Conference Proceedings, vol. 5898 Black Hole Finder Probe (BHFP) - missiya, prednaznachennaya dlya poiska chernyh dyr. Poka eto tol'ko proekt. Dlya ego realizacii planiruetsya provedenie obzora neba v zhestkom rentgene (10-600 keV). A dlya etogo, v svoyu ochered', nuzhno razvivat' novye tehnologii detektorov. Sobstvenno, v stat'e predstavlen proekt CASTER - Coded Aperture Survey Telescope for Energetic Radiation. Eto odin iz prorabatyvaemyh variantov realizacii BHFP.
Authors: J. Espresate Comments: Submitted to RevMexAA Predstavleny dva kataloga. V pervom opisany 133 zvezdy, vokrug kotoryh obnaruzheny ekzoplanety. Vo vtorom - sami ekzoplanety. S odnoi storony, eto bezuslovno poleznaya stat'ya. S drugoi - rezul'taty bystro obnovlyayutsya, poetomu razumno sdelat' popolnyaemyi setevoi resurs, gde otrazhalis' by i poslednie otkrytiya.
Authors: The Pierre Auger Collaboration Comments: 4 pages, 5 figures, 29th ICRC 2005 Kratko rasskazano o pervom etape raboty novogo proekta po nablyudeniyu kosmicheskih luchei. Observatoriya im. P'era Ozhe budet samym krupnym kompleksom dlya issledovaniya kosmicheskih luchei. Poka rabotaet tol'ko chast' apparatury.
Authors: A. Atoyan, C. D. Dermer Comments: 10 pages, 5 figures; to appear in the Proceedings of the Aspen2005 Workshop `Physics at the End of the Galactic Cosmic Ray Spectrum'' (Aspen, April 2005) Avtory stroyat model', v kotoroi chast' kosmicheskih luchei (energii poryadka 1014-1018 eV) svyazana s nedavnim gamma-vspleskom v nashei Galaktike. Chtoby ob'yasnit' dannye nablyudenii trebuetsya vsplesk, proizoshedshii na rasstoyanii poryadka 1 kpk ot Solnca primerno million let nazad.
Authors: J.P. Halpern et al. Comments: 13 pages, 1 figure, to appear in ApJ Letters Anomal'nyi rentgenovskii pul'sar XTE J1810-197 nablyudalsya v aktivnoi faze v 2003 g. V to vremya on byl otkryt kak bystro oslabevayushii ob'ekt s tipichnymi parametrami dlya istochnikov etogo klassa. Vse bylo obychnym, krome dostatochno bystro (mesyacy) ubyvayushei svetimosti. Arhivnye dannye pokazali nalichie slabogo ob'ekta na meste XTE J1810-197 (svetimost' poryadka na dva men'she, chem nablyudavshayasya v 2003 g.). Eto ne edinstvennyi tranzient sredi anomal'nyh rentgenovskih pul'sarov (ARP). Vtoroi ob'ekt s podobnymi svoistvami - AX J1844.8-0256. Avtory dokladyvayut ob obnaruzhenii radioistochnika v napravlenii na XTE J1810-197. Istochnik ne pul'siruyushii. Priroda izlucheniya do konca ne yasna. Vozmozhno, chto veter chastic vysokoi energii obrazuet tumannost' vokrug ARP, kotoraya i proyavlyaet sebya v radio. Avtory obsuzhdayut vozmozhnost' nalichiya plotnoi sredy vokrug XTE J1810-197, chto i privodit k nablyudaemomu radioizlucheniyu. Vtoroi tranzientnyi ARP AX J1844.8-0256 v radio zaregistrirovan ne byl. Odnako, veroyatno chto on nahoditsya dal'she, chem XTE J1810-197 (rasstoyaniya do ARP sil'no neopredelenny).
My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing).
Authors: Caroline Barban, Herve Dole Comments: 4 pages, 5 images, proceedings of the JENAM 2005 (Liege) parallel session on education. Avtory rasskazyvayut o svoem opyte raboty v shkolah Ameriki i Francii. 10-letnie shkol'niki v sotrudnichestve s astronomami-professionalami realizovyvali proekty po Solnechnoi sisteme, gelioseismologii i galaktikam. Avtory schitayut, chto opyt byl bolee chem polozhitel'nyi, i deti uzhe v dostatochno rannem vozraste soprikosnulis' s nastoyashei naukoi.

Authors: Monwhea Jeng Comments: 6 pages, 2 figures Ya perevel expectation bias kak effekt ozhidaniya. Vozmozhno, chto eto ne luchshii variant perevoda, no, na moi vzglyad, on peredaet sut'. A sut' v tom, chto, provodya eksperiment, nacelennyi na poluchenie nekotorogo ozhidaemogo rezul'tata (sleduyushego iz strogoi teorii, ili prosto iz predrassudkov), eksperimentatory zachastuyu imenno etot rezul'tat i poluchayut v rezul'tate kakoi-to oshibki. Oshibka ne obnaruzhivaetsya bystro, t.k. eksperimentatory okazyvayutsya udovletvorennymi rezul'tatami opyta, nahodishimisya v sootvetstvii s ozhidaniyami. Avtor privodit v svoei stat'e neskol'ko interesnyh primerov takogo effekta ozhidaniya.
