The multiwavelength variability of 3C 273
S. Soldi, M. Türler, S. Paltani +11
We present an update of 3C 273's database hosted by the ISDC, completed with data from radio to gamma-ray observations over the last 10 years. We use this large data set to study t…
Cygnus X-3 transition from the ultrasoft to the hard state
V. Beckmann, S. Soldi, G. Belanger +8
Aims: The nature of Cygnus X-3 is still not understood well. This binary system might host a black hole or a neutron star. Recent observations by INTEGRAL have shown that Cygnus X-…
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 observation of the high-mass X-ray transient V0332+53 during the 2005 outburst decline
N. Mowlavi, I. Kreykenbohm, S. E. Shaw +7
The decline of the high mass X-ray transient V0332+53 during the Dec. 2004 to Feb. 2005 outburst is analysed from the data recorded by INTEGRAL. The flux is shown to decrease expon…
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…
