Multiwavelength observations of the blazar bl lacertae: a new fast tev gamma-ray flare
(American Astronomical Society, 2018-03-28)
Combined with measurements made by very-long-baseline interferometry, the observations of fast TeV gamma-ray flares probe the structure and emission mechanism of blazar jets. However, only a handful of such flares have ...
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 ...
Veritas upper limit on the very high energy emission from the radio galaxy ngc 1275
(IOP Publishing, 2009-11-16)
The recent detection by the Fermi gamma-ray space telescope of high-energy gamma-rays from the radio galaxy NGC 1275 makes the observation of the very high energy (VHE: E &gt; 100 GeV) part of its broadband spectrum ...
