Our parent sample is star-forming galaxies with optical drift-scan spectrophotometry from Moustakas & Kennicutt (2006, J/ApJS/164/81) and Moustakas+ (2010, J/ApJS/190/233) that also have Sloan Digital Sky Survey III optical imaging (SDSS-III; Aihara+ 2011ApJS..193...29A). All ...
We present calibrations for star formation rate (SFR) indicators in the ultraviolet, mid-infrared, and radiocontinuumbands, including one of the first direct calibrations of 150 MHz as an SFR indicator. Our calibrationsutilize 66 nearby star-forming galaxies with Balmer-decrement ...
Megahertz peaked-spectrum (MPS) sources have spectra that peak at frequencies below 1 GHz in the observer's frame and are believed to be radio-loud active galactic nuclei (AGN). We recently presented a new method to search for high-redshift AGN by identifying unusually compact MP ...
