Astronet > Hity astro-ph: pervaya polovina 2003 goda

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.

Rezul'taty WMAP

Odnim iz glavnyh (glavnym?) sobytii pervoi poloviny 2003 g. stalo opublikovanie rezul'tatov pervogo goda raboty sputnika WMAP. Nikakih revolyucionnyh izmenenii ne proizoshlo, i eto pravil'no! Znachit, ne vse ploho v nashei kosmologii! Odnako sm. poslednyuyu stat'yu v etom razdele...

Izuchenie centra nashei Galaktiki

Pozhalui, samaya dostovernaya chernaya dyra nahoditsya v centre nashei Galaktiki. Sushestvuyut ochen' zhestkie ogranicheniya, ne pozvolyayushie ob'yasnit' svoistva central'nogo temnogo tela ne privlekaya gipotezu chernoi dyry. Nablyudeniya prodolzhayutsya, i nasha uverennost' krepnet s kazhdym dnem.

Obzory rezul'tatov XMM i Chandra

Sovremennaya astrofizika nahoditsya na zamechatel'noi stadii razvitiya, kogda kazhdye neskol'ko let poyavlyayutsya krupnye instrumenty novogo pokoleniya, pozvolyayushie sdelat' ogromnyi shag vpered. Seichas letayut dve rentgenovskie observatorii: Chandra i HMM-N'yuton. Blagodarya ih rabote my deistvitel'no kazhdyi den' uznaem chto-to novoe o "neistovoi Vselennoi".

Ne znaem my kak vzryvayutsya sverhnovye. Ponyat' fiziku etogo processa - eto vyzov, kotoryi nam brosaet Priroda. Nablyudateli i teoretiki prilagayut ogromnye usiliya, chtoby priblizit'sya k razgadke, no...
