The Hot and Energetic Universe: A White Paper presenting the science theme motivating the Athena+ mission

Kirpal Nandra, +239 more
TL;DR: The Advanced Telescope for High Energy Astrophysics (Athena+) mission as discussed by the authors provides the necessary performance (e.g., angular resolution, spectral resolution, survey grasp) to address these questions and revolutionize our understanding of the Hot and Energetic Universe.
Journal ArticleDOI

Ubiquitous Variability of X-Ray-absorbing Column Densities in Seyfert 2 Galaxies

TL;DR: In this article, a modification of the torus model is proposed, in which an overabundance of slightly dusty broad emission-line region (BELR) clouds obscures the BELR.
Journal ArticleDOI

A huge reservoir of ionized gas around the Milky Way: Accounting for the Missing Mass?

TL;DR: In this article, the authors reported on X-ray observations made with the Chandra X-Ray Observatory probing the warm-hot phase of the CGM of our Milky Way at about 106 K.
Journal ArticleDOI

Chandra Discovery of a Tree in the X-ray Forest towards PKS 2155-304: the Local Filament?

TL;DR: In this article, the authors present the first X-ray detection of resonant absorption from warm/hot local gas either in our Galaxy, or in the Intergalactic space surrounding our Galaxy.
