Veritas observations of day-scale flaring of m 87 in 2010 april
(IOP Publishing, 2012-02-01)
VERITAS has been monitoring the very-high-energy (VHE; > 100 GeV) gamma-ray activity of the radio galaxy M87 since 2007. During 2008, flaring activity on a timescale of a few days was observed with a peak flux of ...
Veritas 2008-2009 monitoring of the variable gamma-ray source m 87
(IOP Publishing, 2010-05-21)
M 87 is a nearby radio galaxy that is detected at energies ranging from radio to very high energy (VHE) gamma rays. Its proximity and its jet, misaligned from our line of sight, enable detailed morphological studies and ...
Veritas observations of the tev binary ls i +61° 303 during 2008-2010
(IOP Publishing, 2011-08-09)
We present the results of observations of the TeV binary LS I + 61 degrees 303 with the VERITAS telescope array between 2008 and 2010, at energies above 300 GeV. In the past, both ground-based gamma-ray telescopes VERITAS ...
Discovery of variability in the very high energy γ-ray emission of 1es 1218+304 with veritas
(IOP Publishing, 2010-01-14)
We present results from an intensive VERITAS monitoring campaign of the high-frequency peaked BL Lac object 1ES 1218+304 in 2008/2009. Although 1ES 1218+304 was detected previously by MAGIC and VERITAS at a persistent level ...
