NED Abstract

Copyright by Royal Astronomical Society. 2002MNRAS.329..209M Weighing black holes with warm absorbers R. Morales and A.C. Fabian ABSTRACT We present a new technique for determining an upper limit for the mass of the black hole in active galactic nuclei showing warm absorption features. The method relies on the balance of radiative and gravitational forces acting on outflowing warm absorber clouds. It has been applied to six objects: five Seyfert 1 galaxies: IC 4329a, MCG-6-30-15, NGC 3516, NGC 4051 and NGC 5548; and one radio-quiet quasar: MR 2251-178. We discuss our result in comparison with other methods. The procedure could also be applied to any other radiatively driven optically thin outflow in which the spectral band covering the major absorption is directly observed. Keywords: galaxies: active - galaxies: Seyfert - X-rays: galaxies.
