... Figure: Massive binary evolutionary track. ... A short glance to this track is sufficient to understand that there are a lot of evolutionary scenario parameters, which affect different stages of the binary evolution. Fortunately, a very limited number of parameters has effect on the compact binary merging rate. ... The most important (and practically unique) parameter changing the galactic binary NS merging rate is the distribution of an additional (kick) velocity imparted to NS at birth. ...

The 2dF QSO Redshift Survey (2QZ) . ... Before jumping into all the finer details of teh survey, a brief non-astronomer's guide to redshift surveys is available. ... The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure . ...

... For every catalog we provide the detailed and maximum full scientific text in separate files, describing the telescope, calibration of observations, columns of tables, etc., from the original paper publications. ... The main list of CATS catalogs has, as a rule, references to original ones or to the site of initial storage, and ftp-access to every catalog. In our database we also used catalogs typed from original paper. But in some cases we corrected the typos or errors in initial texts. ...

... Fortunately, cold H I appears readily as H I self-absorption (HISA) shadows against warmer background H I . Though the HISA phenomenon was first observed in the 1950s, a detailed, systematic study of HISA clouds has only recently become possible with the advent of large-area synthesis surveys like the Canadian and VLA Galactic Plane Surveys. ... Stronger HISA appears concentrated in discrete cloud complexes associated with spiral arm structure. ...

. The elementary methods (that is, the use of real analysis vs. complex analysis) have a long history from Chebyshev to modern times. They lead to great achievements, due to Erdos, Selberg, Bombieri, etc. I recently started a thorough study of these methods, in order to understand their scope. In the talk, I will give a quick survey of this field, and some new observations. Go to the Laboratoire Poncelet home page. Site design by Paul Zinn-Justin
