A view of PKS 2155-304 with XMM-Newton Reflection Grating Spectrometers
I. Cagnoni, F. Nicastro, L. Maraschi +2
We present the high resolution X-ray spectrum of the BL Lac object PKS 2155-304 taken with the RGS units onboard XMM-Newton in November 2000. We detect a OVII Kalpha resonant absor…
Long term X-ray spectral variability of the nucleus of M81
V. La Parola, G. Fabbiano, M. Elvis +3
We have analysed the soft X-ray emission from the nuclear source of the nearby spiral galaxy M81, using the available data collected with ROSAT, ASCA, BeppoSAX and Chandra. The sou…
Toward a Self Consistent Model of the Ionized Absorber in NGC 3783
Y. Krongold, F. Nicastro, N. S. Brickhouse +3
We present a detailed model for the ionized absorbing gas evident in the 900 ksec Chandra HETGS spectrum of NGC 3783. The analysis was carried out with PHASE a new tool designed to…
Chandra Observation of 3C 212: a New Look at the X-ray and UV Absorbers
T. L. Aldcroft, A. Siemiginowska, M. Elvis +3
The red quasar 3C 212 (z=1.049) is one of the most distant and most luminous AGN which has shown evidence of an X-ray warm absorber. In order to further investigate this unusual qu…
The X-ray absorber of PKS2126-158
Fabrizio Fiore, Martin Elvis, Roberto Maiolino +4
BeppoSAX observed the z=3.27 quasar PKS2126-158 on 1999 May 24-28 when its 2-10keV and 0.1-2.5keV fluxes were 1.1E-11 and 4.4E-12 cgs respectively, a factor of 2 higher than in all…
A pulsar-atmosphere model for PSR 0656+14
D. A. Lloyd, R. Perna, P. Slane +2
We present a pulsar-atmosphere (PA) model for modulated thermal X-ray emission from cooling magnetized neutron stars. The model synthesizes the spectral properties of detailed stel…
