SAO is Russia's main centre for ground-based space research. ... The basic instruments of the Observatory are the optical telescope BTA (Big Alt-azimuth Telescope) with a main mirror diameter of 6 m and the radio telescope RATAN-600 with the antenna diameter 600 m. Study of the Universe as a whole, analysis of non-stationary energy release in galactic and extragalactic objects of various types, investigation of evolution and chemical composition of our Galaxy and the nature of solar activity. ...
... The luminescence time dependence for two types of core/shell QDs (CdSe/CdS and CdTe/CdSe ) were investigated and were compared with behavior of naked ones (CdSe). ... Three different types of QDs were used in this work: simple core CdSe QDs, core/shell CdSe/CdS QDs and type II core/shell CdTe/CdSe heterostructures in charge carrier division regime (Fig.1). ... So core/shell nanocrystals demonstrate intermediate behavior between CdSe core-type QDs and CdTe/CdSe core/shell heterostructures. ...

The Earth?s atmosphere is ?a target? for different types of space radiation. ... In the atmosphere high energy particles produce cascades of the secondary particles ? ... Gamma-bursts also produce their ?response? in the atmosphere in the form of Ñherenkov radiation. ... Studies of the described above phenomena is the main goal of the ?Lomonosov? satellite. ...
... We develop a theory of vertical hopping transport in doped superlattices with intentional uncorrelated vertical disorder introduced by controlled random variations of well widths. ... It is shown that due to quasi-equilibrium situation within the wells, the master rate equation for transitions between the electronic states of the structure can be reduced to a truncated rate equation for inter-well transitions only. ...

... Gaseous discs in NGC 252 and in NGC 4513 have decoupled kinematics, and the ionized gas of their rings is certainly excited by young stars. ... Two other, quite isolated S0 galaxies with the UV rings, IC 522 and NGC 446, demonstrate the shock-dominated gas excitation in the UV-detected rings, so their rings may probably have impact origin. ... NGC 4513. ... The UV rings in isolated galaxies IC 522 and NGC 446 may represent the consequences of central impact by a satellite from a highly inclined...
