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,…
Prospects for the polarimetric mapping of the Sgr A molecular cloud complex with IXPE
Riccardo Ferrazzoli, Laura Di Gesu, Immacolata Donnarumma +5
The X-ray polarization degree of the molecular clouds that surround Sgr A* is expected to be greatly lowered because the polarized reflection emission is mixed with the unpolarized…
Reflection nebulae in the Galactic Center: the case for soft X-ray imaging polarimetry
F. Marin, F. Muleri, P. Soffitta +2
The origin of irradiation and fluorescence of the 6.4 keV bright giant molecular clouds surrounding Sgr A*, the central supermassive black hole of our Galaxy, remains enigmatic. Te…
Prospects of 3D mapping of the Galactic Centre clouds with X-ray polarimetry
F. Marin, V. Karas, D. Kunneriath +1
Despite past panchromatic observations of the innermost part of the Milky Way, the overall structure of the Galactic Centre (GC) remains enigmatic in terms of geometry. In this pap…
