Complex X-ray spectral variability in Mkn 421 observed with XMM-Newton
S. Sembay, R. Edelson, A. Markowitz +2
The bright blazar Mkn 421 has been observed four times for uninterrupted durations of ~ 9 - 13 hr during the performance verification and calibration phases of the XMM-Newton missi…
Status of the EPIC/MOS calibration
P. Ferrando, A. F. Abbey, B. Altieri +16
The XMM-Newton observatory has the largest collecting area flown so far for an X-ray imaging system, resulting in a very high sensitivity over a broad spectral range. In order to e…
Monitoring RXTE Observations of Markarian 348: the origin of the column density variations
A. Akylas, I. Georgantopoulos, R. G. Griffiths +5
We analyze 37 RXTE observations of the type 2 Seyfert galaxy Mrk348 obtained during a period of 14 months. We confirm the spectral variability previous reported by Smith et al., in…
The European Photon Imaging Camera on XMM-Newton: The MOS Cameras
M. J. L. Turner, A. Abbey, M. Arnaud
The EPIC focal plane imaging spectrometers on XMM-Newton use CCDs to record the images and spectra of celestial X-ray sources focused by the three X-ray mirrors. There is one camer…
High-resolution X-ray spectroscopy and imaging of supernova remnant N132D
Ehud Behar, Andrew P. Rasmussen, R. Gareth Griffiths +4
The observation of the supernova remnant N132D by the scientific instruments on board the XMM-Newton satellite is presented. The X-rays from N132D are dispersed into a detailed lin…
The Extended X-ray Halo of the Crab-like SNR G21.5-0.9
R. S. Warwick, J-P. Bernard, F. Bocchino +12
Recent XMM-Newton observations reveal an extended (150") low-surface brightness X-ray halo in the supernova remnant G21.5-0.9. The near circular symmetry, the lack of any limb brig…
