Gamma-rays from the quasar PKS 1441+25: story of an escape
(2015-12-20)Outbursts from gamma-ray quasars provide insights on the relativistic jets of active galactic nuclei and constraints on the diffuse radiation fields that fill the universe. The detection of significant emission above 100 ... -
A recent change in the optical and gamma ray polarization of the Crab nebula and pulsar
(Oxford journals, 2015-12-31)We report on observations of the polarization of optical and γ-ray photons from the Crab nebula and pulsar system using the Galway Astronomical Stokes Polarimeter (GASP), the Hubble Space Telescope, Advanced Camera for ... -
VERITAS detection of gamma-ray flaring activity from the BL LAC object 1ES 1727+502 during bright moonlight observations
(American Astronomical Society, 2015-08-01)During moonlit nights, observations with ground-based Cherenkov telescopes at very high energies (VHEs, E > 100 GeV) are constrained since the photomultiplier tubes (PMTs) in the telescope camera are extremely sensitive ...
