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…
A Fundamental Line for Elliptical Galaxies
Preethi Nair, Sidney van den Bergh, Roberto G. Abraham
Recent studies have shown that massive galaxies in the distant universe are surprisingly compact, with typical sizes about a factor of three smaller than equally massive galaxies i…
Gas flows in galaxies: the relative importance of mergers and bars
Sara L. Ellison, David R. Patton, Preethi Nair +4
Galaxy-galaxy interactions and large scale galaxy bars are usually considered as the two main mechanisms for driving gas to the centres of galaxies. By using large samples of galax…
The Environmental Dependence of the Luminosity-Size Relation for Galaxies
Preethi B. Nair, Sidney van den Bergh, Roberto G. Abraham
We have examined the luminosity-size relationship as a function of environment for 12150 SDSS galaxies with precise visual classifications from the catalog of Nair & Abraham (2010a…
On the Fraction of Barred Spiral Galaxies
Preethi B. Nair, Roberto G. Abraham
We investigate the stellar masses of strongly barred spiral galaxies. Our analysis is based on a sample of ~14000 visually-classified nearby galaxies given in Nair & Abraham 2010(a…
A Catalog of Detailed Visual Morphological Classifications for 14034 Galaxies in the Sloan Digital Sky Survey
Preethi B. Nair, Roberto G. Abraham
We present a catalog of detailed visual classifications for 14034 galaxies in the Sloan Digital Sky Survey (SDSS) Data Release 4 (DR4). Our sample includes nearly all spectroscopic…
