The Survival of The Core Fundamental Plane Against Galactic Mergers
Kelly Holley-Bockelmann, Douglas O. Richstone
We have developed an effective simulation method and applied it to the problem of the accretion of very dense secondary companions by tenuous primaries. We have studied the accreti…
Supermassive Black Holes Then and Now
D. Richstone
Recent surveys suggest that most or all normal galaxies host a massive black hole with 1/100 to 1/1000 of the visible mass of the spheroid of the galaxy. Various lines of argument…
Supermassive Black Holes and the Evolution of Galaxies
D. Richstone, E. A. Ajhar, R. Bender +11
Black holes, an extreme consequence of the mathematics of General Relativity, have long been suspected of being the prime movers of quasars, which emit more energy than any other o…
The Dynamical Evolution of Dense Rotating Systems: Paper II. Mergers and Stellar Evolution
John S. Arabadjis, Douglas O. Richstone
We report the results of simulations of dense rotating stellar systems whose members suffer collisions and undergo stellar evolution processes. The initial configuration for each e…
The Dynamical Evolution of Dense Rotating Systems: Paper I. Two-Body Relaxation Effects
John S. Arabadjis, Douglas O. Richstone
This paper, and its companion, investigate the evolution of dense stellar systems due to the influence of two-body gravitational encounters, physical collisions and stellar evoluti…
The Mass Distribution in the Elliptical Galaxy NGC 3377: Evidence for a 2 x 10**8 Solar Mass Black Hole
John Kormendy, Ralf Bender, Aaron S. Evans +1
We have measured the mass distribution in the central 35" = 1.7 kpc of the E5 galaxy NGC 3377. Stellar rotation velocity and velocity dispersion profiles (seeing sigma_* = 0.20 - 0…
