Resolution of a z=1 QSO with adaptive optics.

Abstract (from CDS):

The Adaptive Optics Bonnette (AOB) of the Canada-France-Hawaii Telescope (CFHT) was used to obtain H-band and I-band images of the low-luminosity, optically selected quasar 1055.3+019 at z=1.06. The FWHMs of stars were 0".11 in H and 0".3 in I during these observations, and the detectors used had 0".034 pixels in H and 0".12 pixels in I. Procedures for determining the point-spread function are described. The QSO is clearly resolved in both wave bands, with significant extended flux within 0".1 of the nucleus. Overall, it appears to be elongated in the direction of a knot and connecting feature extending about 1" northeast of the nucleus visible in the H-band image. There are no other evident close companions, but the host galaxy's hybrid luminosity profile and off-centered nucleus indicate recent tidal disturbance. The I-H colors of the host galaxy correspond to an unreddened stellar population that is currently star forming or is within a very short time of ending an initial starburst. The reddening must be small to match any models.
