Description
Studies discerning whether there is a significant correlation between UHECR arrival directions and optical AGN are hampered by the lack of a uniformly selected and complete all-sky AGN catalog. To remedy this, we are preparing such a catalog based on the 2MASS Redshift Survey (2MRS), a spectroscopic sample of ~45,000 galaxies complete to a K magnitude of 11.75 over 91% of the sky. We have analyzed the available optical spectra of these 2MRS galaxies (~80%), in order to identify the AGN amongst them with uniform criteria. A first-stage release of the AGN catalog for the Southern hemisphere using the 6dF Galaxy Survey spectra (100% complete outside the Galactic plane), will be available before the ICRC. Providing a comparably uniform and complete catalog for the Northern sky is more challenging because the spectra for the Northern galaxies were taken with different instruments; its timescale and expected completeness will be reported.
