Comparison of simple mass estimators for slowly rotating elliptical galaxies
N. Lyskova, J. Thomas, E. Churazov +2
We compare the performance of mass estimators for elliptical galaxies that rely on the directly observable surface brightness and velocity dispersion profiles, without invoking com…

An influence of the matter distribution on the positional accuracy of reference sources
T. I. Larchenkova, A. A. Lutovinov, N. S. Lyskova
We consider an influence of a non-stationary gravitational field of the Galaxy on the visible positions of extragalactic sources. A contribution of the baryonic component of the ga…

Stellar kinematics of X-ray bright massive elliptical galaxies
N. Lyskova, E. Churazov, A. Moiseev +2
We discuss a simple and fast method for estimating masses of early-type galaxies from optical data and compare the results with X-ray derived masses. The optical method relies only…
