Commets: 4 pages, 2 figures, latex
Sovremennye kosmologicheskie nablyudatel'nye dannye ukazyvayut na uskorenie rasshireniya Vselennoi. Eto trebuet nalichiya "temnoi energii". Priroda temnoi energii ostaetsya neyasnoi (krome "obychnoi" kosmologicheskoi postoyannoi i t.n. "kvintessencii" mozhet realizovyvat'sya i ryad drugih variantov), a potomu vozmozhny vsyakie spekulyacii. Vot eshe odna iz nih. SMI napisali by: "Amerikanskie uchenye predskazyvayut, chto my razletimsya na kusochki".
Ideya sostoit v tom, chto t.n. "temnaya energiya" yavlyaetsya t.n. "prizrachnoi energiei", u kotoroi summa davleniya i plotnosti energii otricatel'na (sootvetstvuet uravneniyu sostoyaniya s w<-1, chto ne zakryto nablyudeniyami, bolee togo, kak vidno iz risunkov v stat'e nailuchshii nabo parametrov sootvetstvuet w poryadka -3/2). Odnako, polozhitel'naya plotnost' "prizrachnoi energii" stanovitsya beskonechnoi za konechnoe vremya. I v itoge my imeem "Big Rip" - "Bol'shoi Raskol". T.e. vmesto prosto vechnogo rasshireniya v uskoryayusheisya Vselennoi (kogda sohranyayutsya struktury tipa Mlechnnogo Puti, Solnechnoi sistemy, nas s vami...) my budem imet' superrasshirenie, i "poletyat klochki po zakoulochkam".
Citiruem: "Za mesyac do konca Zemlya budet otorvana ot Solnca, za polchasa do konca zemnoi shar razletitsya na kuski.... Molekuly a zatem i atomy budut razorvany za 10^-19 sekund do konca, zatem raspadutsya yadra i nuklony..."
Stat'ya sovsem nebol'shaya, ponyatnaya i soderzhit vse vazhnye ssylki. Tak chto vsem rekomenduem prochest' i zadumat'sya :) Otmetim, chto v segodnyashnei stat'e ukazana vazhnaya svyaz' prizrachnoi energii s model'yu stacionarnoi Vselennoi Hoila-Bondi-Narlikara-...

Tol'ko Chandra mozhet uvidet', chto odin iz bliznecov i sam ne edin. Kastor voobshe govorya sekstet zvezd - shestikratnaya sistema! Odnako, uzhe v nebol'shoi teleskop mozhno razdelit' Kastor A i Kastor V - rasstoyanie mezhdu nimi na nebe 3.8". No to, chto mozhet teleskop na dache v optike - to slozhnaya zadacha dlya sovremennoi rentgenovskoi observatorii! Krome togo, sputniki zapuskayut ne tol'ko radi kartinok, no i radi bolee detal'nyh issledovanii - spektral'nyh. A vot spektry seichas luchshe stroit HMM (potomu, kstati, Chandra bolee izvesten massam - on kartinki luchshe delaet).

SMI napisali by: "Amerikanskie uchenye predskazyvayut, chto my razletimsya na kusochki".
Ideya sostoit v tom, chto t.n. "temnaya energiya" yavlyaetsya t.n.

"temnye gody", dlyashiesya do poyavleniya pervyh kvazarov i pervyh zvezd. Eto "prosvetlenie" nastupaet na krasnyh smesheniyah 20-5 (starye ocenki 5-10, novye - po dannym WMAP - 10-20). V stat'e rasskazyvaetsya o rentgenovskih nablyudeniyah 13 kvazarov na z=4.7-5.4. T.e. eto deistvitel'no odni iz samyh pervyh kvazarov. Hotya eto i ne pervye nablyudeniya kvazarov na z>4, odnako eto ochen' vazhno.

Dannye inogda teryayutsya pri peredache so sputnika na Zemlyu (po raznym prichinam). Kak eto mozhet povliyat' na rezul'taty obzora? Naprimer dlya rabotayushego WMAP ili dlya dozhidayushegosya sputnika Planck?
obzor! astro-ph/0302565 Zvezdnaya koronal'naya astronomiya - obzor (Stellar coronal astronomy - a review)

Korony zvezd izuchayut v osnovnom po ih zhestkomu izlucheniyu. Okolo chetverti veka nazad udalos' otnablyudat' koronu Kapelly (al'fa Voznichego). Odnako zh, novye sputniki (Chandra, N'yuton i dr.) dayut novye vozmozhnosti. V bol'shom obzre avtory obsuzhdayut sovremennoe sostoyanie del i perspektivy.
astro-ph/0302566 Obrazovanie pyli v pervyh galaktikah (Dust Formation In Early Galaxies)
Authors: H L. Morgan, M G. Edmunds
Commets: Submitted MNRAS, 17 pages with 19 figs
Pyl' v dalekih galaktikah stala ochen' vazhnym yavleniem v svyazi s ispol'zovaniem sverhnovyh dlya opredeleniya kosmologicheskih parametrov. Vyskazyvayutsya somneniyu, chto pravil'no uchten vklad pyli v oslablenie sveta sverhnovyh. V dannoi stat'e avtory issleduyut process obrazovaniya pyli v pervyh galaktikah ("pervye" - nemnogo uslovno, rech' idet o krasnyh smesheniyah >1). Rezul'tat sostoit v tom, chto dazhe na z>5 pyli mozhet byt' mnogo.
astro-ph/0302570 Kastor A i Kastor B razresheny v sovmestnyh nablyudeniyah Chandry i HMM-N'yuton (Castor A and Castor B resolved in a simultaneous Chandra and XMM-Newton observation)
Authors: B. Stelzer, V. Burwitz
Commets: accepted for publication in A&A

Tol'ko Chandra mozhet uvidet', chto odin iz bliznecov i sam ne edin. Kastor voobshe govorya sekstet zvezd - shestikratnaya sistema! Odnako, uzhe v nebol'shoi teleskop mozhno razdelit' Kastor A i Kastor V - rasstoyanie mezhdu nimi na nebe 3.8". No to, chto mozhet teleskop na dache v optike - to slozhnaya zadacha dlya sovremennoi rentgenovskoi observatorii! Krome togo, sputniki zapuskayut ne tol'ko radi kartinok, no i radi bolee detal'nyh issledovanii - spektral'nyh. A vot spektry seichas luchshe stroit HMM (potomu, kstati, Chandra bolee izvesten massam - on kartinki luchshe delaet). T.o. ideya sostoyala v sovmestnom nablyudenii dvumya observatoriyami, chtoby potom iz dannyh HMM mozhno bylo vytyanut' horoshie spektry, chto i udalos'. Kastory vidny blagodarya aktivnosti ih koron. O koronal'noi zvezdnoi astronomii sm. vyshe celuyu knigu.
