NED Abstract

Copyright by Royal Astronomical Society. 1993MNRAS.262L..51S Non-equilibrium motions in galaxies and gravitational redshift Massimo Stiavelli and Giancarlo Setti Scuola Normal Superiore, Piazza dei Cavalieri 7, I-56126 Pisa, Italy Istituto di Radioastronomia, via Irnerio 40,I-40128, Bologna, Italy European Southern Observatory Karl-Schwarzschild Str. 2, D-8046 Garching bei Munchen Germany Accepted 1993 April 13. Received 1992 October 19 ABSTRACT We have attempted to detect non-equilibrium motions in the cores of elliptical galaxies by separating radial velocity profiles into their odd and even components, the latter being zero in equilibrium Newtonian systems. Our sample of 24 objects has been assembled by considering published radial velocity profiles with error bars smaller than 10 km s^-1^. We detect such motions for 13 objects, but surprisingly, in 12 of these cases the core is redshifted with respect to the outer parts. Although most individual cases have only a limited statistical significance, the significance for the complete sample is 99.9 per cent. We suggest that this systematic redshift of cores is a result of gravitational redshift. Key words: relativity - galaxies: distances and redshifts - galaxies: elliptical and lenticular, cD.
