An exploratory study of the hard X-ray variability properties of PG quasars with RXTE
M. Guainazzi, F. Fiore, E. Giallongo +3
We have monitored with the RXTE PCA the variability pattern of the 2-20 keV flux in four PG quasars (QSOs) from the Laor et al. (1994) sample. Six observations of each target at re…
PKS 1004+13: A High-Inclination, Highly-Absorbed Radio-Loud QSO -- The First Radio-Loud BAL QSO at Low Redshift?
Beverley J. Wills, W. N. Brandt, A. Laor
The existence of BAL outflows in only radio-quiet QSOs was thought to be an important clue to mass ejection and the radio-loud - radio-quiet dichotomy. Recently a few radio-loud BA…
The PG X-ray QSO sample: Links between the UV-X-ray Continuum and Emission Lines
Beverley J. Wills, M. S. Brotherton, A. Laor +4
The UV to soft X-rays of luminous AGNs dominate their bolometric luminosity, driven by an accretion-powered dynamo at the center. These photons ionize the surrounding gas, thereby…
Constraints on the Cosmic Rays in the Small Magellanic Cloud
Arnon Dar, Ari Laor, Abraham Loeb
We show that recent -ray observations of the Small Magellanic Cloud with EGRET rule out a universal cosmic ray flux only at energies below GeV, while the observed d…
