Detection of enhanced central mass-to-light ratios in low-mass early-type galaxies: Evidence for black holes?

Abstract:

We present dynamical measurements of the central mass-To-light ratio (M/L) of a sample of 27 low-mass early-Type galaxies. We consider all galaxies with 9.7 < log( < 10.5 in our analysis, selecting out galaxies with available high-resolution Hubble Space Telescope (HST) data, and eliminating galaxies with significant central color gradients or obvious dust features. We use the HST images to derive mass models for these galaxies and combine these with the central velocity dispersion ...
