The X-ray Integral Field Unit at the end of the Athena reformulation phase
Philippe Peille, Didier Barret, Edoardo Cucchetti +279
The Athena mission entered a redefinition phase in July 2022, driven by the imperative to reduce the mission cost at completion for the European Space Agency below an acceptable ta…
Revealing the burning and soft heart of the bright bare AGN ESO 141-G55: X-ray broadband and SED analysis
Delphine Porquet, James N. Reeves, Scott Hagen +4
[Abridged] ESO 141-G55 is a nearby X-ray bright BLS1, which has been classified as a bare AGN due to the lack of warm absorption along its line-of-sight, providing an unhampered vi…
Probing the face-on disc-corona system of the bare AGN Mrk 110 from UV to hard X-rays: a moderate changing-state AGN?
Delphine Porquet, Scott Hagen, Nicolas Grosso +4
[Abridged] The X-ray broadband spectra of the bare AGN Mrk 110, obtained by simultaneous XMM-Newton and NuSTAR observations (Nov 2019 and April 2020), are characterised by the pres…
The puzzling X-ray continuum of the quasar MR 2251-178
E. Nardini, J. N. Reeves, D. Porquet +3
We report on a comprehensive X-ray spectral analysis of the nearby radio-quiet quasar MR 2251-178, based on the long-look (~ 400 ks) XMM-Newton observation carried out in November…
A Chandra/HETGS Census of X-ray Variability From Sgr A* During 2012
J. Neilsen, M. A. Nowak, C. Gammie +13
We present the first systematic analysis of the X-ray variability of Sgr A* during the Chandra X-ray Observatory's 2012 Sgr A* X-ray Visionary Project (XVP). With 38 High Energy Tr…
Chandra-HETGS Observations of the Brightest Flare Seen from Sgr A*
M. A. Nowak, J. Neilsen, S. B. Markoff +10
Starting in 2012, we began an unprecedented observational program focused on the supermassive black hole in the center of our Galaxy, Sgr A*, utilizing the High Energy Transmission…
