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 ...
Simultaneous x-ray and t[clc]e[/clc]v observations of a rapid flare from markarian 421
(IOP Publishing, 1999-12-01)
Mrk 421 was observed for about 2 days with BeppoSAX in 1998 April as part of a worldwide multiwavelength campaign. A large, well-defined flare was observed in X-rays. The same flare was observed simultaneously at TeV ...
