The Very Energetic Radiation Imaging Telescope Array System (VERITAS)
S. M. Bradbury, I. H. Bond, A. C. Breslin +32
We give an overview of the current status and scientific goals of VERITAS, a proposed hexagonal array of seven 10 m aperture imaging Cherenkov telescopes. The selected site is Mont…
Hour-Scale Multiwavelength Variability in Markarian 421
M. Catanese, I. H. Bond, S. M. Bradbury +36
Markarian 421 was observed for about four days with BeppoSAX and the Whipple Observatory gamma-ray telescope in April 1998. A pronounced, well-defined, flare with hour-scale variab…
The Flux Variability of Markarian 501 in Very High Energy Gamma Rays
J. Quinn, I. H. Bond, P. J. Boyle +26
The BL Lacertae object Markarian 501 was identified as a source of gamma-ray emission at the Whipple Observatory in March 1995. Here we present a flux variability analysis on sever…
Correlated variability of Mkn 421 at X-ray and TeV wavelengths on timescales of hours
L. Maraschi, G. Fossati, F. Tavecchio +26
Mkn 421 was observed for about two days with BeppoSAX, prior to and partly overlapping the start of a 1 week continuous exposure with ASCA in April 1998, as part of a world-wide mu…
Tev Blazars: Status of Observations
F. Krennrich, S. D. Biller, I. H. Bond +28
The close relation between ground-based TeV observations and satellite borne -ray measurements has been important for the understanding of blazars. The observations which involv…
Limits to Quantum Gravity Effects from Observations of TeV Flares in Active Galaxies
S. D. Biller, A. C. Breslin, J. Buckley +21
We have used data from the TeV gamma-ray flare associated with the active galaxy Markarian 421 observed on 15 May 1996 to place bounds on the possible energy-dependence of the spee…
