The ACS Fornax Cluster Survey. II. The Central Brightness Profiles of Early-Type Galaxies: A Characteristic Radius on Nuclear Scales and the Transition from Central Luminosity Deficit to Excess
Patrick Cote, Laura Ferrarese, Andres Jordan +9
We analyse HST surface brightness profiles for 143 early-type galaxies in the Virgo and Fornax Clusters. Sersic models provide accurate descriptions of the global profiles with a n…
Self-consistent models of triaxial cuspy galaxies with dark matter halos
R. Capuzzo-Dolcetta, L. Leccese, D. Merritt +1
We have constructed realistic, self-consistent models of triaxial elliptical galaxies embedded in triaxial dark matter halos. Self-consistent solutions by means of the standard orb…
Implementing Few-Body Algorithmic Regularization with Post-Newtonian Terms
Seppo Mikkola, David Merritt
We discuss the implementation of a new regular algorithm for simulation of the gravitational few-body problem. The algorithm uses components from earlier methods, including the cha…
The Black Hole Mass of NGC 4151: Comparison of Reverberation Mapping and Stellar Dynamical Measurements
Christopher A. Onken, Monica Valluri, Bradley M. Peterson +11
We present a stellar dynamical estimate of the black hole (BH) mass in the Seyfert 1 galaxy, NGC 4151. We analyze ground-based spectroscopy as well as imaging data from the ground…
Ejection of Supermassive Black Holes from Galaxy Cores
Alessia Gualandris, David Merritt
[Abridged] Recent numerical relativity simulations have shown that the emission of gravitational waves during the merger of two supermassive black holes (SMBHs) delivers a kick to…
Long-Term Evolution of Massive Black Hole Binaries. III. Binary Evolution in Collisional Nuclei
David Merritt, Seppo Mikkola, Andras Szell
[Abridged] In galactic nuclei with sufficiently short relaxation times, binary supermassive black holes can evolve beyond their stalling radii via continued interaction with stars.…
