INTEGRAL observations of AGN in the Galactic Plane
S. Soldi, V. Beckmann, L. Bassani +7
We present results on approximately one year of INTEGRAL observations of six AGN detected during the regular scans of the Galactic Plane. The sample is composed by five Seyfert 2 o…
Characterizing a new class of variability in GRS 1915+105 with simultaneous INTEGRAL/RXTE observations
D. C. Hannikainen, J. Rodriguez, O. Vilhu +14
We report on the analysis of 100 ks INTEGRAL observations of the Galactic microquasar GRS 1915+105. We focus on INTEGRAL Revolution number 48 when the source was found to exhibit a…
Unveiling the Nature of the High Energy Source IGR J19140+0951
J. Rodriguez, C. Cabanac, D. C. Hannikainen +3
We report on high energy observations of IGR J19140+0951 performed with RXTE on three occasions in 2002, 2003 and 2004, and INTEGRAL during a very well sampled and unprecedented hi…
INTEGRAL observations of the field of the BL Lacertae object S5~0716+714
E. Pian, L. Foschini, V. Beckmann
We have performed observations of the blazar S5 0716+714 with INTEGRAL on 2-6 April 2004. In the first months of 2004, the source had increased steadily in optical brightness and h…
INTEGRAL and XMM-Newton Spectral Studies of NGC 4388
V. Beckmann, N. Gehrels, P. Favre +4
We present first INTEGRAL and XMM-Newton observations of a Seyfert galaxy, the type 2 AGN NGC 4388. Several INTEGRAL observations performed in 2003 allow us to study the spectrum i…
Serpens X-1 observed by INTEGRAL
N. Masetti, L. Foschini, E. Palazzi +13
Here we report results of an INTEGRAL-AO1 observation of the X-ray burst and atoll source Ser X-1 performed in May 2003. The object was observed for a total on-source time of 400 k…
