Upper limits on TeV gamma-ray emission from active galactic nuclei

The results of a search for TeV gamma-ray emission from 35 active galactic nuclei (AGNs) using the Whippie Observatory High Resolution Atmospheric Cerenkov Camera are reported. Fifteen of these objects have been detected at GeV energies by the EGRET experiment on the Compton Gamma Ray Observatory. N...
