    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.

    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. Sm. takzhe arxiv:0807.2601, gde idet rech' o tom, kak vozmozhnoe obnaruzhenie legkogo Higgsa na LHC povliyaet na kosmologiyu.

    Comments: 4 pages PDF including 1 color figure, accepted for presentation at the XXIX URSI General Assembly

    Izvestno, chto central'naya chernaya dyra nashei Galaktiki - Sgr A* - demonstriruet vspyshechnuyu aktivnost' v raznyh diapazonah. V stat'e avtory govoryat o vozmozhnosti obnaruzhenii struktur, nahodyashihsya sovsem blizko k gorizontu sobytii, po nablyudeniyam na submillimetrovyh volnah s pomosh'yu interferometrov s bol'shoi bazoi. Poka takie interferencionnye sistemy eshe ne zarabotali, no eto delo sovsem nedalekogo budushego.

    Comments: 4 pages, 1 figure

    Kak vse pomnyat, nedavno eksperiment DAMA snova ob'yavil o signale, kotoryi mozhet byt' rezul'tatom detektirovaniya chastic temnoi materii. Odnoi iz vozmozhnyh interpretacii mogut byt' aksionopodobnye chasticy (psevdoskalyary) s massoi okolo keVa. V dannoi stat'e avtory pokazyvayut, chto takaya interpretaciya vo-pervyh, zakryvaetsya dannymi po solnechnym neitrino, vo-vtoryh - dannymi po starym zvezdam (zvezdam v sharovyh skopleniyah i belym karlikam).
