Vyglyadit krasivo, no ne slishkom li velika dolya temnoi materii po etim dannym - massa plazmy, izluchayushei v rengenovskom diapazone, sostavlyaet v srednem menee 15% ot massy temnogo veshestva, ne govorya uzhe o masse galaktik, izluchayushih v vidimom diapazone? Net li metodologicheskoi oshibki v tom, chto dlya skopleniya galaktik (v usloviyah otsutstviya mezhgalakticheskogo gaza) harakterno neodnorodnoe raspredelenie massy, a dlya oblakov mezhgalakticheskoi plazmy, naoborot, odnorodnoe, i gravitacionnye linzy, obrazovannye skopleniyami i oblakami plazmy, budut po-raznomu iskazhat' izobrazheniya. Po-moemu, ot neodnorodnoi gravitacionnoi linzy, obrazovannoi skopleniem galaktik, lishennyh mezhgalakticheskogo gaza, mozhno ozhidat' sil'nogo iskazheniya formy lezhashih pozadi nee galaktik, v to vremya kak bolee odnorodnaya gravitacionno-plazmennaya linza bol'shoi protyazhennosti mozhet i ne davat' iskazhenii. Esli eto tak, to na osnovanii nablyudeniya iskazhenii nel'zya delat' odnoznachnyi vyvod o nalichii ili otsutstvii massy bez ucheta ee prostranstvennogo raspredeleniya. Hochu eshe raz podcherknut', chto imenno otsutstvie v dannom sluchae v klasterah mezhgalakticheskogo gaza mozhet privodit' k poyavleniyu bolee neodnorodnyh gravitacionnyh linz, chem obychno. Byl by blagodaren za kakie-libo kommentarii po etomu voprosu.
