Where have all the bulges gone?
Leonel Gutierrez, Antti Tamm, John Beckman +3
Several recent studies indicate that bulges are more complex than merely structureless relaxed stellar systems. We study the HST images of a sample of 130 nearby early type (S0-Sab…
The HST/ACS Coma Cluster Survey: I - Survey Objectives and Design
David Carter, Paul Goudfrooij, Bahram Mobasher +34
We describe the HST ACS Coma cluster Treasury survey, a deep two-passband imaging survey of one of the nearest rich clusters of galaxies, the Coma cluster (Abell 1656). The survey…
Trends for Outer Disk Profiles
Peter Erwin, Michael Pohlen, Leonel Gutierrez +1
The surface-brightness profiles of galaxy disks fall into three main classes, based on whether they are simple exponentials (Type I), bend down at large radii (Type II, "truncation…
The Outer Disks of Early-Type Galaxies. I. Surface-Brightness Profiles of Barred Galaxies
Peter Erwin, Michael Pohlen, John E. Beckman
We present a study of 66 barred, early-type (S0-Sb) disk galaxies, focused on the disk surface brightness profile outside the bar region and the nature of Freeman Type I and II pro…
Three Types of Galaxy Disks
M. Pohlen, P. Erwin, I. Trujillo +1
We present our new scheme for the classification of radial stellar surface brightness profiles for disk galaxies. We summarize the current theoretical attempts to understand their…
The Outer Structure of Galactic Disks: Connections Between Bars, Disks, and Environments
Peter Erwin, Michael Pohlen, John E. Beckman +2
Surface-brightness profiles for early-type (S0-Sb) disks exhibit three main classes (Type I, II, and III). Type II profiles are more common in barred galaxies, and most of the time…
