The goal of this survey is to analyze the global trends for development of massive data collections and related infrastructures in the world aimed at the evaluation of the opportunities for the shared usage of such collections during research, decision making and problem solving in various data intensive domains (DIDs) in Russia. The representative set of(More)
How black holes accrete surrounding matter is a fundamental yet unsolved question in astrophysics. It is generally believed that matter is absorbed into black holes via accretion disks, the state of which depends primarily on the mass-accretion rate. When this rate approaches the critical rate (the Eddington limit), thermal instability is supposed to occur(More)
The U, B,V, R, I light curves of the type IIP supernovae (SNe IIP) SN 2005ay and SN 2005cs, and one spectrum for SN 2005cs, are presented and analyzed. We found both events to be fainter than the average SN IIP, with SN 2005cs showing slight brightening in the second half of plateau stage in the V, R, I bands and a low expansion velocity. The effects of two(More)
