Very high‐energy observations of psr b1951+32
(IOP Publishing, 1997-11-01)
PSR B1951 + 32 is a gamma-ray pulsar detected by the Energetic Gamma Ray Experiment Telescope (EGRET) and identified with the 39.5 ms radio pulsar in the supernova remnant CTB 80. The pulsar energy spectrum is consistent ...
Measurement of the multi‐tev gamma‐ray flare spectra of markarian 421 and markarian 501
(IOP Publishing, 1999-01-20)
The energy spectrum of Markarian 421 in flaring states has been measured from 0.3 to 10 TeV using both small and large zenith angle observations with the Whipple Observatory 10 m imaging telescope. The large zenith angle ...
The flux variability of markarian 501 in very high energy gamma rays
(IOP Publishing, 1999-06-20)
The BL Lacertae object Markarian 501 was identified as a source of gamma-ray emission at the Whipple Observatory in 1995 March. Here we present a flux variability analysis on several timescales of the 233 hr data set ...
