Uncovering the geometry of the hot X-ray corona in the Seyfert galaxy NGC4151 with IXPE
V. E. Gianolli, D. E. Kim, S. Bianchi +106
We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy NGC4151. The source has been observed with the Imaging X-ray Polarimetry Explorer (IXPE) for 700 ks,…
The effects of spatially distributed ionisation sources on the temperature structure of HII region
B. Ercolano, N. Bastian, G. Stasinska
Spatially resolved studies of star forming regions show that the assumption of spherical geometry is not realistic in most cases, with a major complication posed by the gas being i…
The Intimate Link Between Accretion and BELR
F. Nicastro, A. Martocchia, G. Matt
In this paper I present evidence suggesting that the absence or presence of Hidden Broad Line Regions (HBLRs) in Seyfert 2 galaxies is regulated by the rate at which matter accrete…
The High Energy Resolution View of Ionized Absorbers in AGN
F. Nicastro, F. Fiore, G. Matt
A number of emission and absorption features are expected to be visible in high energy resolution X-ray spectra of type 1 AGN with ionized gas along the line of sight (so called "w…
