GRO J1655-40: Early Stages of the 2005 Outburst
N. Shaposhnikov, J. Swank, C. R. Shrader +4
The black-hole X-ray binary transient GRO J1655-40 underwent an outburst beginning in early 2005. We present the results of our multi-wavelength observational campaign to study the…
The Hard X-ray 20-40 keV AGN Luminosity Function
V. Beckmann, S. Soldi, C. R. Shrader +2
We have compiled a complete extragalactic sample based on 25,000 deg^2 to a limiting flux of 3E-11 ergs/cm**2/sec (7,000 deg^2 to a flux limit of 1E-11 ergs/cm**2/sec) in the 20 -…
Fourier resolved spectroscopy of 4U 1543-47 during the 2002 outburst
P. Reig, I. E. Papadakis, C. R. Shrader +1
We have obtained Fourier-resolved spectra of the black-hole binary 4U 1543-47 in the canonical states (high/soft, very high, intermediate and low/hard) observed in this source duri…
Results from the First INTEGRAL AGN Catalogue
V. Beckmann, S. Soldi, C. R. Shrader +1
We present results based on the first INTEGRAL AGN catalogue. The catalogue includes 42 AGN, of which 10 are Seyfert 1, 17 are Seyfert 2, and 9 are intermediate Seyfert 1.5. The fr…
The First INTEGRAL AGN Catalog
V. Beckmann, N. Gehrels, C. R. Shrader +1
We present the first INTEGRAL AGN catalog, based on observations performed from launch of the mission in October 2002 until January 2004. The catalog includes 42 AGN, of which 10 a…
XTE J1550-564: INTEGRAL Observations of a Failed Outburst
S. J. Sturner, C. R. Shrader
The well known black-hole X-ray binary transient XTE J1550-564 underwent an outburst during the spring of 2003 which was substantially underluminous in comparison to previous perio…
