Probing the hot circumgalactic medium of external galaxies in X-ray absorption II: a luminous spiral galaxy at
Smita Mathur, Sanskriti Das, Anjali Gupta +1
The circumgalactic medium (CGM) is the most massive baryonic component of a spiral galaxy, shock heated to about K for an galaxy. The CGM of the Milky Way has…
X-Ray Detection of the Galaxy's Missing Baryons in the Circum-Galactic Medium of L Galaxies
Fabrizio Nicastro, Yair Krongold, Taotao Fang +10
The amount of baryons hosted in the disks of galaxies is lower than expected based on the mass of their dark-matter halos and the fraction of baryon-to-total matter in the universe…
The hot circumgalactic medium of the Milky-Way: new insights from XMM-Newton observations
Joy Bhattacharyya, Sanskriti Das, Anjali Gupta +2
We present XMM-Newton observations around the sightline of Mrk 421. The emission spectrum of the Milky Way circumgalactic medium (CGM) shows that a two phase model is a better fit…
Thermal and chemical properties of the eROSITA bubbles from Suzaku observations
Anjali Gupta, Smita Mathur, Josh Kingsbury +2
The X-ray bright bubbles at the Galactic Center provide an opportunity to understand the effects of feedback on galaxy evolution. The shells of the eROSITA bubbles show enhanced X-…
The hot circumgalactic medium of the Milky Way: evidence for super-virial, virial, and sub-virial temperature, non-solar chemical composition, and non-thermal line broadening
Sanskriti Das, Smita Mathur, Anjali Gupta +1
For the first time, we present the simultaneous detection and characterization of three distinct phases at K in absorption, using deep observations tow…
Detection of a Multi-Phase Ultra-Fast Wind in the Narrow-Line Seyfert 1 Galaxy Mrk 1044
Y. Krongold, A. L. Longinotti, M. Santos-Lleo +6
We present a detailed analysis of XMM-Newton X-ray spectra of the Narrow-Line Seyfert 1 galaxy Mrk 1044. We find robust evidence for a multi-phase, ultra-fast outflow, traced by fo…
