Study of the X-ray emission mechanism of radio-loud narrow-line Seyfert 1 galaxy
H. Shirakawa, Y. Fukazawa, Y. Tanaka +2
1H0323+342 is one of narrow-line radio-loud Seyfert 1 galaxies (RL-NLS1), which is a new class of gamma-ray emitting AGNs. Narrow-line Seyfert 1 galaxies (NLS1) have a small-mass b…
The detection of Broad Iron K and L line emission in the Narrow-Line Seyfert 1 Galaxy 1H0707-495 using XMM-Newton
A. C. Fabian, A. Zoghbi, R. R. Ross +14
Since the discovery of the first broad iron-K line in 1995 from the Seyfert Galaxy MCG--6-30-15, broad iron-K lines have been found in several other Seyfert galaxies, from accretin…
X-ray hiccups from SgrA* observed by XMM-Newton. The second brightest flare and three moderate flares caught in half a day
D. Porquet, N. Grosso, P. Predehl +14
[truncated] In Spring 2007, we observed SgrA* with XMM with a total exposure of ~230ks. We have performed timing and spectral analysis of the new X-ray flares detected during this…
A search for cyclotron resonance features with INTEGRAL
Y. Okada, H. Niko, M. Kokubun +6
We present an INTEGRAL observation of the Cen-Crux region in order to search the electron cyclotron resonance scattering features from the X-ray binary pulsars. During the AO1 200k…
Long-term spectral changes in the partial-covering candidate NLS1 1H 0707-495
L. C. Gallo, Y. Tanaka, Th. Boller +3
We compare two XMM-Newton observations of the Narrow-Line Seyfert 1 galaxy 1H 0707-495 separated by two years, and discuss the results in terms of the partial-covering phenomenon.…
The enhancement and decrement of the Sunyaev-Zeldovich effect towards the ROSAT Cluster RXJ0658-5557
P. Andreani, H. Boehringer, G. Dall'Oglio +9
We report simultaneous observations at 1.2 and 2 mm, with a double channel photometer on the SEST Telescope, of the X-ray cluster RXJ0658-5557 in search for the Sunyaev-Zel'dovich…
