... Currently, there is very little information on comets which are active beyond the orbit of Jupiter. ... Previous observations conducted by our team with the SAO RAS 6-m telescope showed that some of these comets have extended tails dissimilar to the tails of comets forming at close heliocentric distances. ... We for the first time measured the linear polarization of scattered emission for the two distant comets C/2010 S1 (LINEAR) and C/2010 R1 (LINEAR) at heliocentric distances of 5.9-7.0 au. ...

The seminar is supported by the grant of Federal Programm "Integration" . ... Measuring the Hubble Constant from Reverberating Accretion Discs in AGNs . We show how wavelength-dependent time delays between continuum flux variations of active galactic nuclei (AGNs) can be used to test the standard black hole--accretion disc paradigm, by measuring the temperature structure T(R) of the gaseous material surrounding the purported black hole. ...

Galaxies are diffuse objects which are imaged against a background of finite brightness and noise. Galaxies which have the maximum contrast with respect to this background are the ones that are first discovered. ... These galaxies have been missed to date but active surveys for them are underway. ... In this page we present several examples of these newly discovered Low Surface Brightness galaxies as well as examples of high surface brightness galaxies. ...

. Authors: A.A. Suchkov , V.A. Marakov . Journal: Pis'ma Astron. Zh., 1976, v.2, p.38-385. Metallisity function of globular clusters in the Galaxy is constructed. It is found to have three "humps". This leads to a conclusion that there were three metal enrichment outbursts during the period of globular cluster formation. The constraints on the nature of metal sourses and on the early evolution of Galaxy are considered.
