We present a simple estimate of the mass 'deficits' in cored spheroids, as a function of galaxy mass and radius within the galaxy. Previous attempts to measure such deficits depended on fitting some functional form to the profile at large radii extrapolating inwards; this is sensitive to the assumed functional form and does not allow for variation in nuclear profile shapes. For example, we show that literally interpreting the residuals from a single/cored Sersic function fit as implied 'deficit… Expand

Surface brightness and intrinsic luminosity of ellipticals
We show that the surface brightness profiles of elliptical galaxies can be parametrized using a linear superposition of two or three components, each of which is described by functions developed inExpand
Sizing up Partially Depleted Galaxy Cores
We have modeled the inner surface brightness profiles of 39 alleged "core" galaxies with the core-Sersic model, and provide new physical parameters for the largest ever sample of "core" galaxies fitExpand
Depleted Galaxy Cores and Dynamical Black Hole Masses
Shallow cores in bright, massive galaxies are commonly thought to be the result of scouring of stars by mergers of binary supermassive black holes. Past investigations have suggested correlationsExpand

Two channels of supermassive black hole growth as seen on the galaxies mass–size plane
We investigate the variation of black hole masses (Mbh) as a function of their host galaxy stellar mass (Mstar) and half-light radius (Re). We confirm that the scatter in Mbh within this plane isExpand
A remarkably large depleted core in the Abell 2029 BCG IC 1101
We report the discovery of an extremely large (R_b ~ 2"77 ~ 4.2 kpc) core in the brightest cluster galaxy, IC 1101, of the rich galaxy cluster Abell 2029. Luminous core-Sersic galaxies containExpand
The dynamical fingerprint of core scouring in massive elliptical galaxies
The most massive elliptical galaxies have low-density centers or cores that differ dramatically from the high-density centers of less massive ellipticals and bulges of disk galaxies. These cores haveExpand
