The Centers of Early-Type Galaxies with HST. V. New WFPC2 Photometry

Tod R. Lauer, S. M. Faber, Karl Gebhardt +14

We analyze HST+WFPC2 images of 77 early-type galaxies. Brightness profiles are classed into "core" or "power-law" forms. Cores are typically rounder than power-law galaxies. Nearly…

Black Hole Mass Determinations From Orbit Superposition Models are Reliable

Douglas Richstone, Karl Gebhardt, Monique Aller +13

We show that orbit-superposition dynamical models (Schwarzschild's method) provide reliable estimates of nuclear black hole masses and errors when constructed from adequate orbit l…
