Astronet > Obzory preprintov astro-ph

Ne pretenduya na polnotu, ya hotel by brosit' vzglyad na raboty, poyavivshiesya v astrofizicheskoi chasti Arhiva v pervoi polovine 2003 g. Dlya etogo ya ispol'zoval nashi spiski "luchshih iz luchshih". Eto raboty, kotorye my s Mihailom Prohorovym vydelili v nashih ezhenedel'nyh Obzorah. Zdes' ocheviden perekos v storonu nashih professional'nyh i okoloprofessional'nyh interesov, poetomu eto dovol'no sub'ektivnaya vyborka. Krome togo, v nee voshlo lish' okolo 1 procenta rabot, poyavivshihsya v Arhive (a skol'ko ih ne poyavilos'!). I tem ne menee: chto zhe interesnogo mozhno bylo prochest' v Arhive astro-ph za pervuyu polovinu etogo goda?

Diskussiya po eksperimentu Kopeikina-Fomalona

Spisok ne uporyadochen po znachimosti sobytii. Tem ne menee, na pervoe mesto hochetsya postavit' diskussiyu po povodu etogo eksperimenta, tochnee po ego interpretacii. Eto interesnyi primer sovremennoi nauchnoi diskussii. Tochka v etom voprose eshe ne postavlena. Budem sledit' za sobytiyami.

Nizhe ssylki na tri raboty: opisanie eksperimenta, teoreticheskaya interpretaciya, kritika interpretacii.

Krupnomasshtabnaya struktura: teoriya i nablyudeniyaa

Sredi bol'shih dostizhenii kosmologii poslednih let dvadcati osoboe mesto zanimaet izuchenie krupnomasshtabnoi struktury Vselennoi. Seichas eto (naryadu s dannymi o reliktovom izluchenii, o pervichnom nukleosinteze, nu i konechno zhe o rasshirenii Vselennoi) odin iz chetyreh kraeugol'nyh kamnei kosmologii. Osnovnyh napravlenii dva: slozhnye chislennye raschety i obzornye nablyudeniya. Pervaya stat'ya - pro komp'ternoe modelirovanie, vtoraya posvyashena krupneishemu obzoru.

Navernoe, prosto sverhmassivnymi chernymi dyrami uzhe nikogo ne udivish'. A dvoinymi sverhmassivnymi chernymi dyrami? A "malomassivnymi sverhmassivnymi", kotorye nahodyatsya v galaktikah, gde byt' im ne polagaetsya?

Vot kak ono bylo eti polgoda. Konechno, bylo i mnogo drugogo interesnogo ( pishite, chto bylo interesno imenno vam). No bylo i eto, tozhe ochen' i ochen'.

Esli prodolzhat' suzhat' vyborku (chto kraine tyazhelo i sverhsub'ektivno), to iz etoi polusotni rabot ya by vydelil takie:

"O glavnom" - rezul'taty WMAP.

Otdel'nyi krasivyi nablyudatel'nyi rezul'tat - "splyusnutaya zvezda" Ahernar i "vihlyayushii" dzhet pul'sara v Parusah.

Chislennoe modelirovanie - struktura voidov ("vselennaya v miniatyure").

Krasivaya ideya - "razryv Vselennoi".

Interesnye obzory po ekzotike - fakticheski vse raboty, upomyanutye v sootvetstvuyushem razdele vyshe (kazhdyi iz nih zasluzhivaet otdel'noi bol'shoi nauchno-populyarnoi stat'i).

Sostavlyaite vashi hit-parady v etoi teme na forume Zvezdocheta (nuzhno budet zaregistrirovat'sya, no eto bystro) ili na forume Scientific.Ru

Podrobnye referaty kazhdoi iz upomyanutyh statei mozhno naiti v nashih Obzorah (sm. takzhe ANKi Dnya). Naiti iskomyi referat ochen' legko, t.k. nomer preprinta postroen po principu GodMesyacPoryadkovyi_nomer.

Hochu poblagodarit' universitet Padui za vozmozhnost' posvyashat' stol'ko vremeni obzoram preprintov astro-ph, prichem na russkom yazyke.
