Search for high redshift dual, binary, and offset AGN, using gravitational lensing for milli-arcsec X-ray astrometry.
Abstract
We propose to use rich archival Chandra observations of eight highly magnified lensed quasars to elucidate the location of the X-ray emission relative to the radio and optical origins. This is a pioneering project, which can enable us to use Chandra observations in a novel way that can provide an unprecedented X-ray astrometric accuracy of a milliarcsecond, <10 pc for sources at cosmological distances. The technique can improve X-ray astrometry and resolution by even 3 orders of magnitude, which in turn will allow us to probe the inner regions of selected quasars for dual, binary, or offset active galactic nuclei (AGN). These sources were originally observed with very different objectives, and the analysis we propose has never been applied.
