Constraints on the very high energy emission from bl lacertae objects
(IOP Publishing, 2004-03-01)We present results from observations of 29 BL Lacertae objects, taken with the Whipple Observatory 10 m gamma-ray telescope between 1995 and 2000. The observed objects are mostly at low redshift (z<0.2), but observations ... -
Cutoff in the t[clc]e[/clc]v energy spectrum of markarian 421 during strong flares in 2001
(IOP Publishing, 2001-10-10)Exceptionally strong and long- lasting flaring activity of the blazar Mrk 421 occurred between 2001 January and March. Based on the excellent signal- to- noise ratio of the data, we derive the energy spectrum between 260 ... -
Multiwavelength observations of a flare from markarian 501
(IOP Publishing, 1997-10-01)We present multiwavelength observations of the BL Lacertae object Markarian 501 (Mrk 501) in 1997 between April 8 and April 19. Evidence of correlated variability is seen in very high energy (VHE; E greater than or similar ... -
Observation of m87 at 400 gev with the whipple 10 meter telescope
(IOP Publishing, 2004-07-20)We present results from observations taken with the Whipple 10 m very high energy gamma-ray telescope with maximal sensitivity at 400 GeV during 39 hr between 2000 and 2003 in the direction of the giant radio galaxy M87. ...
