The soft X-ray/NLR connection: a single photoionized medium?
Stefano Bianchi, Matteo Guainazzi, Marco Chiaberge
We present a sample of 8 nearby Seyfert 2 galaxies observed by HST and Chandra. All of the sources present soft X-ray emission which is coincident in extension and overall morpholo…
Obscured AGN: clues from high-resolution imaging and spectroscopy
Stefano Bianchi, Matteo Guainazzi, Marco Chiaberge
We present a sample of 8 Seyfert 2 galaxies observed by HST, Chandra and XMM-Newton. All of the sources present soft X-ray emission which is coincident in extension and overall mor…
XMM-Newton discovery of soft X-ray absorption in the high-z superluminous Blazar RBS 315
E. Piconcelli, M. Guainazzi
We present the analysis and the results of a 20 ks XMM-Newton observation of the extremely X-ray loud (L_X ~ 5 x 10^{47} erg/s) flat-spectrum radio quasar RBS 315 at a redshift of…
Crab: the standard X-ray candle with all (modern) X-ray satellites
M. G. F. Kirsch et al.
Various X-ray satellites have used the Crab as a standard candle to perform their calibrations in the past. The calibration of XMM-Newton, however, is independent of the Crab nebul…
A search for changing-look AGN in the Grossan catalog
S. Bianchi, M. Guainazzi, G. Matt +4
We observed with XMM-Newton 4 objects selected from the Grossan catalog, with the aim to search for new 'changing-look' AGN. The sample includes all the sources which showed in sub…
X-ray Emission from NGC 1808: More than a Complex Starburst
E. Jimenez-Bailon, M. Santos-Lleo, M. Dahlem +5
Earlier observations of NGC 1808 in various wavebands (X-ray, optical, near-infrared, radio) provided evidence for the existence of either a starburst or a Seyfert 2 nucleus. We he…
