Weak Lensing Constraints on Dark Matter Halos Tereasa Brainerd Institute for Astrophysical Research, Boston University, USA It is currently thought that all large galaxies reside within massive dark matter halos. Despite the apparent ubiquity of such halos and their importance for developing a complete picture of the history of galaxy formation, the characteristic parameters (e.g., total mass, physical extent, and shape) of these objects remain largely unconstrained at present. ...

THE ARGUMENT AGAINST LONG EXTRAGALACTIC DISTANCE SCALE Gaseous discs of S0 -- Sd galaxies appears to be gravitationally stable or close to stability. Dependence of the gravitational stability parameter of gaseous disc $M_g/M_c$ upon the color index $(B-V)^0_T$ which reflects a relative number of young stars, is found. Here $M_g$ is total mass of gas in a galaxy, $M_c$ - mass of gas which corresponds to marginal stability of gaseous disc at distances from center. ...
