A multiwavelength view of the tev blazar markarian 421: correlated variability, flaring, and spectral evolution
(IOP Publishing, 2005-09-01)
We report results from an intensive multiwavelength monitoring campaign on the TeV blazar Mrk 421 over the period of 2003 - 2004. The source was observed simultaneously at TeV energies with the Whipple 10 m telescope and ...
A very high energy gamma‐ray spectrum of 1es 2344+514
(IOP Publishing, 2005-12-01)
The BL Lacertae (BL Lac) object 1ES 2344+514 (1ES 2344), at a redshift of 0.044, was discovered as a source of very high energy (VHE) gamma rays by the Whipple collaboration in 1995 (Catanese et al.). This detection was ...
Spectrum of very high energy gamma‐rays from the blazar 1es 1959+650 during flaring activity in 2002
(IOP Publishing, 2005-03-01)
The blazar 1ES 1959+650 was observed in a flaring state with the Whipple 10 m Imaging Atmospheric Cerenkov Telescope in 2002 May. A spectral analysis has been carried out on the data from that time period, and the resulting ...
A survey of unidentified egret sources at very high energies
(IOP Publishing, 2005-05-10)
The Whipple Observatory 10 m γ-ray telescope has been used to survey the error boxes of EGRET unidentified sources in an attempt to find counterparts at energies of 350 GeV and above. Twenty-one unidentified sources ...
