Comments: 14 pages, 10 figures, Proceedings of the SPIE meeting "Space Telescopes and Instrumentation II: Ultraviolet to Gamma Ray 2008", Marseille (2008) NeXT - novyi yaponskii rentgenovskii sputnik, kotoryi planiruetsya zapustit' v 2013 godu. Apparat koe-chto zaimstvuet u "Suzaku" (osobenno v smysle orbity, raboty i tp.), no budet zametno tyazhelee. Na bortu budet dva instrumenta, rabotayushih v zhestkom rentgene, dva - v myagkom, i gamma-detektor. Odin iz myagkih priborov budet rabotat' kak spektrometr s razresheniem okolo 7 eV. Vse instrumenty s uzkim polem zreniya (do 9 minut), krome, konechno, gamma-detektora. arxiv:0807.2088 Poisk na vysokih chastotah radiopul'sarov v boksah EGRET (A high frequency search for radio pulsars in EGRET error boxes) Authors: M.J. Keith et al. Comments: 5 pages, accepted for publication in MNRAS Izvestno, chto v kataloge gamma-detektora EGRET okolo poloviny istochnikov ne otozhdestvleny. Predpolagaetsya, chto mnogie iz nih mogut byt' radiopul'sarami. Okolo goda nazad gruppa avtorov provodila glubokii poisk pul'sarov v 56 boksah oshibok, nichego ne bylo obnaruzheno. V etoi stat'e govorit'sya o poiske v treh oblastyah lokalizacii. No tut rech' idet uzhe o bolee vysokih chatostah - 3.1 GGc. Obnaruzhen pul'sar PSR J1028-5819 s periodom okolo 90 millisekund. Avtory polagayut, chto on i yavlyaetsya odnim iz treh gamma-istochnikov. Na nizkih chastotah tam nichego ne bylo naideno, tak chto, vozmozhno, i dlya drugih oblastei poisk stoit povtorit' na vysokih chastotah. arxiv:0807.2106 Proishozhdenie i evolyuciya magnitarov (Origin and evolution of magnetars) Authors: Lilia Ferrario, D.T.

Razumeetsya, dlya populyacionnoi modeli avtoram prihoditsya delat' ryad predpolozhenii, mnogie iz kotoryh mozhno osparivat'. Tem ne menee, popytka dovol'no interesnaya. obzor arxiv:0807.2244 Temnaya materiya i LHC: kakova svyaz'? (Dark Matter and LHC: What is the Connection?) Authors: Gordon Kane, Scott Watson Comments: 25 pages, 2 figures, Invited review for Modern Physics Letters A Zakanchivayutsya raboty, predshestvuyushie zapusku Bol'shogo Adronnogo Kollaidera (LHC) v CERNe. Krome svoei osnovnoi zadachi - issledovaniya Higgsovskogo bozona - ustanovka mozhet vnesti vklad i v nashe ponmianie prirody temnoi materii. Odnako mnogie pochemu-to polagayut, chto mozhno s bol'shoi nadezhnost' ozhidat', chto LHC dast tut chto-to principial'no novoe i sushestvennoe. V obzore avtory obsuzhdayut, chto zhe sobstvenno mozhno zhdat' ot LHC (i chego nel'zya) v smysle issledovaniya svoistv temnogo veshestva. Obzor napisan ochen' dostupno, tak chto ego mozhno smelo vsem rekomendovat'. Dlya teh zhe, kto ishet bolee detal'nuyu informaciyu, v obzore privoditsya mnogo ssylok.
