Imaging Redshift Estimates for Fermi BL Lacs
Abstract/Contents
- Abstract
- We have measured i images of BL Lacertae objects (BL Lacs) to detect or constrain the flux of the host galaxy. Under common standard candle assumptions these data provide estimates of, or lower bounds on, the redshift. Our targets are a set of flat-spectrum radio counterparts of high flux Fermi Large Area Telescope (LAT) sources, with deep spectral observations showing them to be continuum-dominated BL Lacs. In this sample, 6 of 11 BL Lacs yielded significant host detections, with standard candle redshifts z=0.13-0.58. Our estimates and lower bounds are generally in good agreement with other redshifts estimates for these sources.
