The AGNatha team will be using WISE data to identify anomalous AGN in Gaia.
Context. Gaia is a very precise astrometric and photometric survey mission which has amassed data on millions of objects across the sky. Some of the objects are Active Galactic Nuclei (AGN) for which Gaia has incorrectly determined a significant parallax or proper motion. These determinations are known to be incorrect due to the vast distances at which these AGN are found.
Aims. We aim to construct a catalog of these incorrectly measured AGN in order to provide a new resource for locating interesting or unusual AGN. We also aim to characterize these AGN based on their surrounding environments and their optical characteristics.
Methods. We will identify several AGN candidates using the WISE catalog and then cross-reference these with Gaia to confirm measurements of parallax or proper motion. AGN with parallax or proper motion measurements having signal to noise ratios greater than three will then be studied visually using sky survey catalogs to determine which factors could lead to significant measurements of parallax or proper motion.
