New Gamma-Ray Probe of the Baryonic Dark Matter
A. F. Iyudin, V. Burwitz, J. Greiner +2
We expand on the recently reported detections of the gamma-ray resonant absorption along the line of sight toward gamma-ray bright quasars (QSOs), like 3C279. We propose to use thi…
INTEGRAL broadband spectroscopy of Vela X-1
P. Kretschmar, R. Staubert, I. Kreykenbohm +11
The wind-accreting X-ray binary pulsar and cyclotron line source Vela X-1 has been observed extensively during INTEGRAL Core Program observations of the Vela region in June-July an…
First results on the HMXRB Pulsar SAXJ2103.5+4545 with INTEGRAL
L. Sidoli, S. Mereghetti, S. Larsson +6
We report on the preliminary timing and spectral analysis of the High Mass X-ray Binary Pulsar SAXJ2103.5+4545 as observed with INTEGRAL during the Galactic Pla n Scan of the Core…
The variable X/gamma-ray spectrum of the Seyfert 2 galaxy NGC 7172
Felix Ryde, Juri Poutanen, Roland Svensson +2
A broad band X-, gamma-ray spectral study of the Seyfert 2 galaxy NGC 7172 is presented. We use our ASCA observations from May 1995 and combine these with the CGRO OSSE data from M…
A simple formula for the thermal pair annihilation line emissivity
Roland Svensson, Stefan Larsson, Juri Poutanen
We introduce a simple and convenient fitting formula for the thermal annihilation line from pair plasmas in cosmic sources. The fitting formula is accurate to 0.04\% and is valid a…
