The 2010 May Flaring Episode of Cygnus X-3 in Radio, X-Rays, and γ-Rays
Peter K. G. Williams, John A. Tomsick, Arash Bodaghee +7
In 2009, Cygnus X-3 (Cyg X-3) became the first microquasar to be detected in the GeV γ-ray regime, via the satellites Fermi and AGILE. The addition of this new band to the observat…
When A Standard Candle Flickers
Colleen A. Wilson-Hodge, Michael L. Cherry, Wayne H. Baumgartner +27
The Crab Nebula is the only hard X-ray source in the sky that is both bright enough and steady enough to be easily used as a standard candle. As a result, it has been used as a nor…
The absorption-dominated model for the X-ray spectra of type I active galaxies: MCG-6-30-15
L. Miller, T. J. Turner, J. N. Reeves
MCG-6-30-15 is the archetypal example of a type I active galaxy showing broad "red-wing" emission in its X-ray spectrum at energies below the 6.4 keV Fe K-alpha emission line and a…
Searching for New Physics with Ultrahigh Energy Cosmic Rays
Floyd W. Stecker, Sean T. Scully
Ultrahigh energy cosmic rays that produce giant extensive showers of charged particles and photons when they interact in the Earth's atmosphere provide a unique tool to search for…
A Chandra view of NGC 3621: a bulgeless galaxy hosting an AGN in its early phase?
M. Gliozzi, S. Satyapal, M. Eracleous +2
We report the detection of a weak X-ray point source coincident with the nucleus of the bulgeless disk galaxy NGC 3621, recently discovered by Spitzer to display high ionization mi…
The Supercritical Pile GRB Model: The Prompt to Afterglow Evolution
A. Mastichiadis, D. Kazanas
The "Supercritical Pile" is a very economical GRB model that provides for the efficient conversion of the energy stored in the protons of a Relativistic Blast Wave (RBW) into radia…
