• (The American Astronomical Society, 2012)
This paper examines star formation (SF) in relatively massive, primarily early-type galaxies (ETGs) at $z \sim 0.1$. A sample is drawn from bulge-dominated Galaxy Evolution Explorer/Sloan Digital Sky Survey (GALEX/SDSS) ...
• (The American Astronomical Society, 2012)
The shutdown of star formation in galaxies is generally termed "quenching." Quenching may occur through a variety of processes, e.g., active galactic nucleus (AGN) feedback, stellar feedback, or the shock heating of gas ...
• (The American Astronomical Society, 2012)
We present results from a study of the globular cluster (GC) systems of four spiral and S0 galaxies imaged as part of an ongoing wide-field survey of the GC systems of giant galaxies. The target galaxies - the SB0 galaxy ...
• (The American Astronomical Society, 2012)
We present MMT spectroscopic observations of H II regions in 42 low luminosity galaxies in the Spitzer Local Volume Legacy survey. For 31 of the 42 galaxies in our sample, we were able to measure the temperature sensitive ...
• (The American Astronomical Society, 2012)
During a wide-field narrowband $\text{H}\alpha$ imaging survey, we noted the presence of numerous isolated emission-line point sources in the data. These objects could represent ultra-low-luminosity galaxies at low-redshift ...
