The Surface Mass Density and Structure of the Outer Disk of NGC 628

Stéphane Herbert-Fort, Dennis Zaritsky, Daniel Christlein +1

We study the kinematics of GALEX-selected H_alpha knots in the outer disk (beyond R25) of NGC 628 (M74), a galaxy representative of large, undisturbed, extended UV (Type 1 XUV) dis…

The Dependence of the Galaxy Luminosity Function on Environment

Daniel Christlein

We present luminosity functions for galaxies in loose groups in the Las Campanas Redshift Survey, differentiated by their environment (defined by the line-of-sight velocity dispers…

A Spectroscopic Study of the H-alpha Surface Brightness Profiles in the Outer Disks of Galaxies

Daniel Christlein, Dennis Zaritsky, Joss Bland-Hawthorn

The surface brightness profile of H-alpha emission in galaxies is generally thought to be confined by a sharp truncation, sometimes speculated to coincide with a star formation thr…

The IR Luminosity Functions of Rich Clusters

Lei Bai, George H. Rieke, Marcia J. Rieke +2

We present MIPS observations of the cluster A3266. About 100 spectroscopic cluster members have been detected at 24 micron. The IR luminosity function in A3266 is very similar to t…

Disentangling Morphology, Star Formation, Stellar Mass, and Environment in Galaxy Evolution

Daniel Christlein, Ann Zabludoff

We present a study of the spectroscopic and photometric properties of galaxies in six nearby clusters. We perform a partial correlation analysis on our dataset to investigate wheth…

Can Early Type Galaxies Evolve from Fading the Disks of Late Types?

Daniel Christlein, Ann Zabludoff

We examine whether early-type galaxies in clusters may have evolved from later types by the fading of their disks (e.g., as a result of ram-pressure stripping or strangulation) or…
