Authors: Steven E. Boggs et al. Comments: 32 pages, 14 figures, submitted to ApJ Pochti dva goda nazad proizoshla gigantskaya vspyshka magnitara SGR 1806-20, a stat'i vse poyavlyayutsya i poyavlyayutsya.... V dannoi predstavlen detal'nyi analiz na osnove dannyh indiiskogo sputnika RHESSI. Krome gamma-detektorov, kotorye "oslepli" v moment maksimuma vspyshki, na ego bortu byli i detektory chastic, kotorye vse-taki pozvolyayut poluchit' dannye o vspleske dazhe vo vremya naibol'shego potoka.

Hoerandel Comments: Lecture given at the International School of Cosmic Ray Astrophysics, 15th Course: Astrophysics at Ultra-high Energies, 20-27 June 2006, Ettore Majorana Centre Erice, Sicily, Italy Dlya menya vsegda bylo udivitel'nym, chto pri stol' malom obilii dannyh fizika i astrofizika kosmicheskih luchei predstavlyayut soboi stol' obshirnuyu oblast' issledovanii. Desyatiletiyami lyudi b'yutsya nad razgadkoi prirody detalei v energeticheskom spektre etih chastic, priletayushih k nam iz kosmosa. Schitaetsya, chto ponimanie etih izlomov v spektre (koleno i t.n. "vtoroe koleno") dolzhno rasskazat' nam ochen' mnogoe ne tol'ko o proishozhdenii etih chastic, no i o Galaktike i Vselennoi. V obzore razbirayutsya nablyudatel'nye metodiki, primenyashiesya dlya issledovaniya chastic v diapazone energii ot 10^14 do 10^18 eV i opisyvayutsya novye rezul'taty. Sm. takzhe obzor astro-ph/0611884, posvyashennyi toi zhe tematike.

Poka issledovaniya polyarizacii rentgenovskogo izlucheniya astronomicheskih ob'ektov nahodyatsya v zachatochnom sostoyanii: to avariya (kak s yaponskimi apparatami), to konkurenty zarubyat proekt s horoshim polyarimetrom (kak s nashim SRG). Tem ne menee, rano ili pozdno takoi instrument poyavitsya, vozmozhno dazhe na sputnike s rossiiskim uchastiem (novyi SRG). V obzore v osnovnom obsuzhdayutsya polyarimetricheskie issledovaniya neitronnyh zvezd. Krome etogo, opisano sostoyanie del so stroyashimisya instrumentami i razvivayushimisya tehnologiyami.

Seichas, kak izvestno, dostraivayutsya ochen' krupnye ustanovki, kotorye budut iskat' neitrino s pomosh'yu opticheskih metodov v tolshe vody ili antarkticheskogo l'da. Odnako dlya neitrino ochen' vysokih energii takie metody poiska ne podhodyat. Nuzhno chto-to inoe. O radiometodah ya uzhe nedavno pisal, ih budut ispol'zovat' v antarkticheskih eksperimentah. V etoi zhe stat'e rech' idet ob akusticheskih metodah, kotorye predpolagaetsya primenyat' k morskih eksperimentah.

Odnako MGS - ochen' slozhnyi ob'ekt dlya izucheniya. V obzore avtory summiruyut nashe znanie o MGS i rassuzhdayut o tom, chto i kak mozhno eshe uznat' izuchaya ee. Sm. takzhe astro-ph/0611637, gde obsuzhdaetsya vopros ob obogashenii MGS tyazhelymi elementami.
Authors: Adam J. Burgasser Comments: 16 pages, 3 figures, accepted to ApJ Part 1; Vozmozhno, chto okolo odnoi iz blizkih zvezd s ekzoplanetoi obnaruzhen sputnik na ochen' shirokoi orbite (iz-za togo, chto orbita ochen' shirokaya, ustanovit' fizicheskuyu svyaz' neprosto). Esli eto v samom dele tak, to obnaruzhennyi ob'ekt yavlyaetsya analogom shiroko obsuzhdavsheisya v svoe vremya Nemezidy. Sputnik v neskol'ko desyatkov raz (20-50) legche Solnca. Pri svoem priblizhenii k central'noi zvezde on mozhet vozmutit' orbity planet i, esli na nih est' zhizn', sygrat' rol' zvezdy-ubiicy.
Authors: Michael P. Muno Comments: 8 pages, 3 figures. Uses aipproc.cls. To appear in the proceedings of the conference ``The Multicoloured Landscape of Compact Objects and their Explosive Origins'', 2006 June 11--24, Cefalu, Sicily, to be published by AIP Mne stat'ya pokazalas' ochen' interesnoi. V samom dele, my ploho ponimaem, kakie iz massivnyh zvezd prevrashayutsya v neitronnye zvezdy, a kakie v chernye dyry. Yasno tol'ko, chto net kakogo-to odnogo universal'nogo predela na massu, vyshe kotoroi zvezda yavlyaetsya praroditelem chernoi dyry.

Authors: S. Oslowski, R. Moderski, T. Bulik, K. Belczynski Comments: Submitted to Astronomy and Astrophysics Sredi mnozhestva sobytii mikrolinzirovaniya est' neskol'ko, dlya kotoryh ocenka massy govorit o tom, chto linzoi mogla byt' neitronnaya zvezda ili chernaya dyra. S pomosh'yu chislennogo modelirovaniya avtory vosproizvodyat populyaciyu odinochnyh neitronnyh zvezd i chernyh dyr v Galaktike i izuchayut vopros o tom, skol'ko sobytii mikrolinzirovaniya mozhno ozhidat' ot etih ob'ektov i kak oni budut raspredeleny na nebe. Rezul'taty takovy: sobytiya proishodyat v osnovnom v predelah 10 gradusov ot napravleniya na centr Galaktiki, temp sobytii - neskol'ko shtuk v god.

Authors: Horst R. Beyer Comments: 23 pages Spornaya, no dovol'no interesnaya stat'ya. Avtor skoree zashishaet religiyu ot popytok zamenit' ee naukoi. Osnovnoe utverzhdenie avtora svoditsya k tomu, chto zakonchennye fizicheskie kartinu mira postoyanno smenyayut drug druga, i utverzhdenie ob absolyutnosti, naprimer, sovremennoi kartiny yavlyaetsya skoree utverzhdeniem very, chem nauki.

Chast' rassmotreniya avtoram udalos' prodelat' analiticheskii, dlya chasti - trebuetsya chislennoe modelirovanie.
Authors: Bert Schroer Comments: 24 pages Podrobnaya kritika teorii strun.
Authors: Alexander Zaitsev Comments: 7 pages Sobstvenno, stat'ya posvyashena poslaniyam vnezemnym civilizaciyam. Avtor razvivaet svoi izvestnyi tezis o tom, chto glupo nadeyat'sya chto-to ulovit', esli sami ne peredaem.
Authors: Werner Marx, Hermann Schier, Ole Krogh Andersen Comments: 9 pages, 3 figures, 1 table Navernoe stoit zavesti special'nuyu rubriku dlya statei po citirovaniyu, ibo tema menya interesuet, i raboty takoi napravlennosti prakticheski vsegda vklyuchayutsya v obzory. V dannom sluchae avtory rassmatrivayut izmenenie tempa citirovaniya so vremenem. Takaya velichina, razumeetsya, mozhet byt' ispol'zovana tol'ko dlya ocenki vklada ochen' horosho citiruyushihsya uchenyh, poskol'ku dlya gladkosti krivyh nuzhna dovol'no bol'shaya statistika. Takzhe dovol'no interesno provedennoe avtorami sravnenie neskol'kih issledovatel'skih institutov.
