The efficient low-mass Seyfert MCG-05-23-016
V. Beckmann, T. J. -L. Courvoisier, N. Gehrels +5
The Seyfert 1.9 galaxy MCG-05-23-016 has been shown to exhibit a complex X-ray spectrum. This source has moderate X-ray luminosity, hosts a comparably low-mass black hole, but accr…
Analysis of extremely low signal-to-noise ratio data from INTEGRAL/PICsIT
Piotr Lubinski
The PICsIT detector onboard the INTEGRAL satellite was designed to provide information about emission in the soft gamma-ray band for many bright sources. Due to strong and variable…
An intense state of hard X-ray emission of Cyg X-1 observed by INTEGRAL coincident with TeV measurements
J. Malzac, P. Lubinski, A. A. Zdziarski +3
We present INTEGRAL light curves and spectra of the black-hole binary Cyg X-1 during a bright event that occurred in 2006 September, and which was simultaneous with a detection at…
2003--2005 INTEGRAL and XMM-Newton observations of 3C 273
M. Chernyakova, A. Neronov, T. J. -L. Courvoisier +9
The aim of this paper is to study the evolution of the broadband spectrum of one of the brightest and nearest quasars 3C 273. We analyze the data obtained during quasi-simultaneous…
INTEGRAL and RXTE monitoring of GRS 1758-258 in 2003 and 2004. A transition from the dim soft state to the hard state
K. Pottschmidt, M. Chernyakova, A. A. Zdziarski +3
The Galactic Center black hole candidate (BHC) GRS 1758-258 has been observed extensively within INTEGRAL's Galactic Center Deep Exposure (GCDE) program in 2003 and 2004, while als…
The High Energy Spectrum of NGC 4151
V. Beckmann, C. R. Shrader, N. Gehrels +5
We present the first INTEGRAL observations of the type 1.5 Seyfert galaxy NGC 4151. Combining several INTEGRAL observations performed during 2003, totaling about 400 ks of exposure…
