AGN feedback in action: a new powerful wind in 1SXPS J050819.8+172149 ?
Abstract
Context. Galaxy merging is widely accepted to be a driving factor in galaxy formation and evolution, while the feedback from actively accreting nuclei is thought to regulate the black hole-bulge coevolution and the star formation process.
Aims: In this context, we focused on
Methods: The X-ray emission of
Results: The slope of the continuum is Γ ~ 1.8, with an intrinsic column density of ~2.4 × 1022cm-2, and a de-absorbed luminosity of ~4 × 1042 erg s-1 in the 2-10 keV band. Our observations provide a tentative (2.1σ) detection of a blueshifted Fe xxvi absorption line (rest-frame E ~ 7.8 keV), thus suggesting the discovery of a new candidate powerful wind in
