The spectrum of tev gamma rays from the crab nebula

Hillas, A. M.; Akerlof, C. W.; Biller, S. D.; Buckley, J. H.; Carter‐Lewis, D. A.; Catanese, M.; Cawley, M. F.; Fegan, D. J.; Finley, J. P.; Gaidos, J. A.; Krennrich, F.; Lamb, R. C.; Lang, M. J.; Mohanty, G.; Punch, M.; Reynolds, P. T.; Rodgers, A. J.; Rose, H. J.; Rovero, A. C.; Schubnell, M. S.; Sembroski, G. H.; Vacanti, G.; Weekes, T. C.; West, M.; Zweerink, J. (IOP Publishing, 1998-08-20)

The spectrum of gamma rays from the Crab Nebula has been measured in the energy range 500 GeV-8 TeV at the Whipple Observatory by the atmospheric Cerenkov technique. Two methods of analysis that were used to derive spectra, ...

The flux variability of markarian 501 in very high energy gamma rays

Quinn, J.; Bond, I. H.; Boyle, P. J.; Bradbury, S. M.; Breslin, A. C.; Buckley, J. H.; Burdett, A. M.; Gordo, J. Bussons; Carter‐Lewis, D. A.; Catanese, M.; Cawley, M. F.; Fegan, D. J.; Finley, J. P.; Gaidos, J. A.; Hall, T.; Hillas, A. M.; Krennrich, F.; Lamb, R. C.; Lessard, R. W.; Masterson, C.; McEnery, J. E.; Moriarty, P.; Rodgers, A. J.; Rose, H. J.; Samuelson, F. W.; Sembroski, G. H.; Srinivasan, R.; Vassiliev, V. V.; Weekes, T. C. (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 ...

Multiwavelength observations of a flare from markarian 501

Catanese, M.; Bradbury, S. M.; Breslin, A. C.; Buckley, J. H.; Carter-Lewis, D. A.; Cawley, M. F.; Dermer, C. D.; Fegan, D. J.; Finley, J. P.; Gaidos, J. A.; Hillas, A. M.; Johnson, W. N.; Krennrich, F.; Lamb, R. C.; Lessard, R. W.; Macomb, D. J.; McEnery, J. E.; Moriarty, P.; Quinn, J.; Rodgers, A. J.; Rose, H. J.; Samuelson, F. W.; Sembroski, G. H.; Srinivasan, R.; Weekes, T. C.; Zweerink, J. (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 ...

Measurement of the multi‐tev gamma‐ray flare spectra of markarian 421 and markarian 501

Krennrich, F.; Biller, S. D.; Bond, I. H.; Boyle, P. J.; Bradbury, S. M.; Breslin, A. C.; Buckley, J. H.; Burdett, A. M.; Gordo, J. Bussons; Carter‐Lewis, D. A.; Catanese, M.; Cawley, M. F.; Fegan, D. J.; Finley, J. P.; Gaidos, J. A.; Hall, T.; Hillas, A. M.; Lamb, R. C.; Lessard, R. W.; Masterson, C.; McEnery, J. E.; Mohanty, G.; Moriarty, P.; Quinn, J.; Rodgers, A. J.; Rose, H. J.; Samuelson, F. W.; Sembroski, G. H.; Srinivasan, R.; Vassiliev, V. V.; Weekes, T. C. (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 ...
