VERITAS Observations of day-scale flaring of M87 in 2010 April
E. Aliu, T. Arlen, T. Aune +88
VERITAS has been monitoring the very-high-energy (VHE; >100GeV) gamma-ray activity of the radio galaxy M87 since 2007. During 2008, flaring activity on a timescale of a few days wa…
The 2010 very high energy gamma-ray flare & 10 years of multi-wavelength observations of M 87
The H. E. S. S. Collaboration, :, A. Abramowski +442
Abridged: The giant radio galaxy M 87 with its proximity, famous jet, and very massive black hole provides a unique opportunity to investigate the origin of very high energy (VHE;…
VERITAS Search for VHE Gamma-ray Emission from Dwarf Spheroidal Galaxies
The VERITAS Collaboration, V. A. Acciari, T. Arlen +73
Indirect dark matter searches with ground-based gamma-ray observatories provide an alternative for identifying the particle nature of dark matter that is complementary to that of d…
VERITAS 2008 - 2009 monitoring of the variable gamma-ray source M87
The VERITAS Collaboration, V. A. Acciari, E. Aliu +84
M87 is a nearby radio galaxy that is detected at energies ranging from radio to VHE gamma-rays. Its proximity and its jet, misaligned from our line-of-sight, enable detailed morpho…
Discovery of very high energy gamma rays from PKS 1424+240 and multiwavelength constraints on its redshift
The VERITAS Collaboration, V. A. Acciari, The Fermi Collaboration +4
We report the first detection of very-high-energy (VHE) gamma-ray emission above 140 GeV from PKS 1424+240, a BL Lac object with an unknown redshift. The photon spectrum above 140…
A connection between star formation activity and cosmic rays in the starburst galaxy M 82
V. A. Acciari, E. Aliu, T. Arlen +89
Although Galactic cosmic rays (protons and nuclei) are widely believed to be dominantly accelerated by the winds and supernovae of massive stars, definitive evidence of this origin…
