X-ray variability of the Narrow Line Seyfert 1 Galaxy PKS 0558-504
W. Brinkmann, P. Arevalo, M. Gliozzi +1
We present results from several XMM-Newton observations of the radio loud Narrow-line Seyfert 1 galaxy (NLS1) PKS 0558-504. We find evidence for strong and persistent X-ray variabi…
On the origin of the X-rays and the nature of accretion in NGC 4261
M. Gliozzi, R. M. Sambruna, W. N. Brandt
We report on the X-ray properties of the radio galaxy NGC 4261, combining information from the XMM, Chandra, and SAX satellites. Goals of this study are to investigate the origin o…
The XMM-Newton View of the Nucleus of NGC 4261
R. M. Sambruna, M. Gliozzi, M. Eracleous +2
We present the first results from an XMM-Newton observation of the FRI galaxy NGC 4261, which harbors a supermassive black hole and a low-ionization nuclear emission-line region (L…
