When Is a Bulge Not a Bulge? Inner Disks Masquerading as Bulges in NGC 2787 and NGC 3945
Peter Erwin, Juan Carlos Vega Beltran, Alister W. Graham +1
We present a detailed morphological, photometric, and kinematic analysis of two barred S0 galaxies with large, luminous inner disks inside their bars. We show that these structures…
Quantitative Morphology of Galaxies in the Core of the Coma Cluster
C. M. Gutierrez, I. Trujillo, J. A. L. Aguerri +2
We present a quantitative morphological analysis of 187 galaxies in a region covering the central 0.28 square degrees of the Coma cluster. Structural parameters from the best-fitti…
HST detection of spiral structure in two Coma Cluster dwarf galaxies
Alister W. Graham, Helmut Jerjen, Rafael Guzman
We report the discovery of (stellar) spiral-like structure in Hubble Space Telescope images of two dwarf galaxies (GMP 3292 and GMP 3629) belonging to the Coma cluster. GMP 3629 is…
A New Empirical Model for the Structural Analysis of Early-type Galaxies and a Critical Review of the Nuker Model
Alister W. Graham, Peter Erwin, Ignacio Trujillo +1
The Nuker law was designed to match the inner few (~3-10) arcseconds of predominantly nearby (< 30 Mpc) early-type galaxy light-profiles; it was never intended to describe an entir…
An investigation into the prominence of spiral galaxy bulges: The Data
Alister W. Graham
The best-fitting B, R, I and K-band (Sersic R^(1/n) bulge + exponential disk) model parameters for the de Jong & van der Kruit (1994) sample of 86 spiral galaxies are made electron…
HST photometry of dwarf elliptical galaxies in Coma, and an explanation for the alleged structural dichotomy between dwarf and bright elliptical galaxies
Alister W. Graham, Rafael Guzman
We have analyzed archival HST F606W images of 18 dwarf elliptical (dE) galaxy candidates in the Coma Cluster. We model the full radial extent of their light-profiles by simultaneou…
