The Active Nuclei Content of the RASS BSC/NVSS sample
Abstract
I will present recent results from a complete sample of galaxies which are both radio sources in the 1.4 GHz NRAO VLA Sky Survey (NVSS) and X-ray sources in the ROSAT All-Sky Survey Bright Source Catalog (BSC). These catalogues were cross-identified using a technique akin to the likelihood ratio. This sample of 1500 objects is composed of nearly normal galaxies, Seyferts, quasars, and clusters with an average redshift of <z> 0.1. The dominant population is active nuclei, ranging from local low luminosity AGN out to distant QSO's and BL Lacs. I have obtained redshifts and classifications for a magnitude-limited (J <= 18 and δ >= -20° ) subsample. The spectra permit a calculation of multivariate radio-X-ray-optical luminosity functions of these local galaxies and model evolutionary effects as a function of classification type. The sample has statistically significant numbers to probe a variety of classes and investigate nearby low lumninosity objects. F.
