Detecting Relativistic X-ray Jets in High-Redshift Quasars
Kathryn McKeough, Aneta Siemiginowska, C. C. Cheung +12
We analyze Chandra X-ray images of a sample of 11 quasars that are known to contain kiloparsec scale radio jets. The sample consists of five high-redshift (z >= 3.6) flat-spectrum…
Unusual Flaring Activity in the Blazar PKS 1424-418 during 2008-2011
S. Buson, F. Longo, S. Larsson +24
Context. Blazars are a subset of active galactic nuclei (AGN) with jets that are oriented along our line of sight. Variability and spectral energy distribution (SED) studies are cr…
Multifrequency Studies of the Peculiar Quasar 4C +21.35 During the 2010 Flaring Activity
M. Ackermann, M. Ajello, A. Allafort +288
The discovery of rapidly variable Very High Energy (VHE; E > 100 GeV) gamma-ray emission from 4C +21.35 (PKS 1222+216) by MAGIC on 2010 June 17, triggered by the high activity dete…
A Tidal Disruption Event in a Nearby Galaxy Hosting an Intermediate Mass Black Hole
Davide Donato, Stephen Bradley Cenko, Stefano Covino +9
We report the serendipitous discovery of a bright point source flare in the Abell cluster 1795 with archival EUVE and Chandra observations. Assuming the EUVE emission is associated…
Hunting for treasures among the Fermi unassociated sources: a multi-wavelength approach
F. Acero, D. Donato, R. Ojha +6
The Fermi Gamma-ray Space Telescope has been detecting a wealth of sources where the multi-wavelength counterpart is either inconclusive or missing altogether. We present a combina…
Long-Term Multiwavelength Studies of High-Redshift Blazar 0836+710
A. Akyuz, D. J. Thompson, D. Donato +7
Aims. The observation of gamma -ray flares from blazar 0836+710 in 2011, following a period of quiescence, offered an opportunity to study correlated activity at different waveleng…
