A log N(HI) = 22.6 DLA in a dark gamma-ray burst: the environment of GRB 050401
D. Watson, J. P. U. Fynbo, C. Ledoux +33
The optical afterglow spectrum of GRB050401 (at z=2.8992+/-0.0004) shows the presence of a DLA, with log(nHI)=22.6+/-0.3. This is the highest column density ever observed in a DLA,…
The X-ray spectrum of NGC 7213 and the Seyfert--LINER connection
R. L. C. Starling, M. J. Page, G. Branduardi-Raymont +3
We present an XMM-Newton observation of the Seyfert-LINER galaxy NGC 7213. The RGS soft X-ray spectrum is well fitted with a power law plus soft X-ray collisionally ionised thermal…
X-ray emission line gas in the LINER galaxy M81
M. J. Page, A. A. Breeveld, R. Soria +5
We present the soft X-ray spectrum of the LINER galaxy M81 derived from a long observation with the XMM RGS. The spectrum is dominated by continuum emission from the active nucleus…
Complex resonance absorption structure in the X-ray spectrum of IRAS13349+2438
M. Sako, S. M. Kahn, E. Behar +8
The luminous infrared-loud quasar IRAS 13349+2438 was observed with the XMM-Newton Observatory as part of the Performance Verification program. The spectrum obtained by the Reflect…
