A catalog of bulge, disk, and total stellar mass estimates for the Sloan Digital Sky Survey
J. Trevor Mendel, Luc Simard, Michael Palmer +2
We present a catalog of bulge, disk, and total stellar mass estimates for ~660,000 galaxies in the Legacy area of the Sloan Digital Sky Survey Data Release 7. These masses are base…
Galaxy pairs in the Sloan Digital Sky Survey - VIII: The observational properties of post-merger galaxies
Sara L. Ellison, J. Trevor Mendel, David R. Patton +1
In order to investigate the effects of galaxy mergers throughout the interaction sequence, we present a study of 10,800 galaxies in close pairs and a smaller sample of 97 post-merg…
Galaxy pairs in the Sloan digital sky survey - VII: The merger -- luminous infra-red galaxy connection
Sara L. Ellison, J. Trevor Mendel, Jillian M. Scudder +2
We use a sample of 9397 low z galaxies with a close companion to investigate the connection between mergers and luminous infra-red (IR) galaxies (LIRGs). The pairs are selected fro…
Towards a physical picture of star-formation quenching: the photometric properties of recently-quenched galaxies in the Sloan Digital Sky Survey
J. Trevor Mendel, Luc Simard, Sara L. Ellison +1
We select a sample of young passive galaxies from the Sloan Digital Sky Survey Data Release 7 in order to study the processes that quench star formation in the local universe. Quen…
Galaxy Pairs in the Sloan Digital Sky Survey - V. Tracing changes in star formation rate and metallicity out to separations of 80 kpc
Jillian M. Scudder, Sara L. Ellison, Paul Torrey +2
We present a sample of 1899 galaxies with a close companion taken from the SDSS DR7. The galaxy pairs are selected to have velocity differences < 300 km/s, projected separations (r…
The dependence of galaxy group star formation rates and metallicities on large scale environment
Jillian M. Scudder, Sara L. Ellison, J. Trevor Mendel
We construct a sample of 75,863 star forming galaxies with robust metallicity and star formation rate measurements from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7), from…
Galaxy pairs in the Sloan Digital Sky Survey - IV: Interactions trigger AGN
Sara L. Ellison, David R. Patton, J. Trevor Mendel +1
Galaxy-galaxy interactions are predicted to cause gas inflows leading to enhanced nuclear star formation. In this paper we test the further prediction that the gas inflows lead to…
The impact of gas inflows on star formation rates and metallicities in barred galaxies
Sara L. Ellison, Preethi Nair, David R. Patton +3
The star formation rates (SFRs) and metallicities of a sample of 294 galaxies with visually classified, strong, large-scale bars are compared to a control sample of unbarred disk g…
Compact groups in theory and practice -- IV. The connection to large-scale structure
J. Trevor Mendel, Sara L. Ellison, Luc Simard +2
We investigate the properties of photometrically-selected compact groups (CGs) in the Sloan Digital Sky Survey. In this paper, the fourth in a series, we focus on understanding the…
Galaxy Pairs in the Sloan Digital Sky Survey - III: Evidence of Induced Star Formation from Optical Colours
David R. Patton, Sara L. Ellison, Luc Simard +2
We have assembled a large, high quality catalogue of galaxy colours from the Sloan Digital Sky Survey Data Release 7, and have identified 21,347 galaxies in pairs spanning a range…
Galaxy Pairs in the Sloan Digital Sky Survey - II: The Effect of Environment on Interactions
Sara L. Ellison, David R. Patton, Luc Simard +3
We use a sample of close galaxy pairs selected from the Sloan Digital Sky Survey Data Release 4 (SDSS DR4) to investigate in what environments galaxy mergers occur and how the resu…
