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…
Ultraviolet Spectroscopy of Supernovae: The First Two Years of Swift Observations
F. Bufano, S. Immler, M. Turatto +13
We present the entire sample of ultraviolet (UV) spectra of supernovae (SNe) obtained with the Ultraviolet/Optical Telescope (UVOT) on board the Swift satellite during the first 2…
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…
A Smoking Gun in the Carina Nebula
Kenji Hamaguchi, Michael F. Corcoran, Yuichiro Ezoe +8
The Carina Nebula is one of the youngest, most active sites of massive star formation in our Galaxy. In this nebula, we have discovered a bright X-ray source that has persisted for…
Pre-nova X-ray observations of V2491 Cyg (Nova Cyg 2008b)
A. Ibarra, E. Kuulkers, J. P. Osborne +12
Classical novae are phenomena caused by explosive hydrogen burning on an accreting white dwarf. So far, only one classical nova has been identified in X-rays before the actual opti…
