Not Where You Left Them: Displaced -Rays and X-Rays Reveal the Cosmic Ray Scattering Rate
Manami Roy, Mark R. Krumholz, Roland M. Crocker +1
Modern X-ray and -ray instruments are revealing a growing class of Galactic non-thermal sources whose emission centroids are measurably offset from the nearest plausible sites o…
To Survive or to Shatter: The Impact of Cosmic Rays on the Fate of Stripped Cold Clouds
Manami Roy, Kung-Yi Su, Stephanie Tonnesen +3
Does cosmic ray (CR) pressure matter for the circumgalactic medium (CGM)? Despite growing interest, this remains a debated question, complicated by limited observational constraint…
Detection of 'super-virial' gas in the Circumgalactic medium of the Milky Way towards PKS 2155-304
Mukesh Singh Bisht, Sanskriti Das, Smita Mathur +3
We present the first simultaneous detection of four distinct highly ionized absorbing phases using Chandra and XMM-Newton grating spectra toward the blazar PKS 2155…
Where is the Supervirial Gas? III. Insights from X-ray Shadow Observations and a revised Model for the Soft Diffuse X-ray Background
Anjali Gupta, Smita Mathur, Joshua Kingsbury +5
Shadow observations provide a powerful tool to separate foreground components of the soft diffuse X-ray background (SDXB) from the background components. Such observations have now…
