Session 39 - AGN Surveys.
Display session, Tuesday, January 14
The Hubble Deep Field gives us an unprecedented view of our
universe and an opportunity to study a wide range of
questions in galaxy evolution and cosmology.
Here, we will focus on the search for faint quasars and AGN
in the crude combined images using a multicolor imaging
analysis that has proven very successful in recent years.
To produce a catalog of objects in the field, we used the
FOCAS package for object detection with particular care
to the set of input parameters used to minimize spurious
detections. For each detected source we measured aperture
magnitudes in several different apertures using the IRAF
PHOT routine. For object classification we have chosen not
to use the built in FOCAS routines, instead we have
developed classification schemes that closely resemble
those of Flynn at al. (1996) to distinguish resolved
from unresolved objects in the Hubble Deep Field. We
generated synthetic quasar spectra in the range
