Chasing the Elusive Blazar with STACEE

Corbin Covault (CWRU)

STACEE is an experiment to detect gamma-rays from astrophysical sources in the range around 50 to 300 GeV. This is a very interesting range for observing blazars since this the the range where the instrinsic inverse-Compton spectra are expected to cut off at the source AND it is also the range where absorption due to intergalactic diffuse optical and UV light from galaxies is expected to attenuate the spectra for sources in the Z range from 0.1 to about 1.0. Both of these phenomena are very interesting and several measurements of different blazar-type AGN will be required ultimately to disentangle these two effects.
