Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
Philip J. Humphrey, David A. Buote, Fabrizio Brighenti +2
We present new mass measurements for the supermassive black holes (SMBHs) in the centres of three early-type galaxies. The gas pressure in the surrounding, hot interstellar medium…
Weighing the Quiescent Central Black Hole in an Elliptical Galaxy with X-ray Emitting Gas
Philip J. Humphrey, David A. Buote, Fabrizio Brighenti +2
We present a Chandra study of the hot ISM in the giant elliptical galaxy NGC4649. In common with other group-centred ellipticals, its temperature profile rises with radius in the o…
On the dynamics of the satellite galaxies in NGC 5044
Andreas Faltenbacher, William G. Mathews
The NGC 5044 galaxy group is dominated by a luminous elliptical galaxy which is surrounded by ~160 dwarf satellites. The projected number density profile of this dwarf population d…
Confrontation of Intracluster and Interstellar Gas in Cluster-Centered Elliptical Galaxies: M87 in Virgo and NGC 4874 in Coma
Fabrizio Brighenti, William G. Mathews
X-ray observations of M87 in the Virgo cluster and NGC 4874 in Coma reveal that the gas temperature beyond about 50 kpc from these cD galaxies is comparable to the virial temperatu…
