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…

Probing the Warm-Hot Circumgalactic Medium with broad OVI and X-rays

Smita Mathur, Anjali Gupta, Sanskriti Das +2

Most of the baryonic mass in the circumgalactic medium (CGM) of a spiral galaxy is believed to be warm-hot, with temperature around K. The narrow OVI absorption lines probe a…

Super-virial temperature or Neon overabundance?: Suzaku observations of the Milky Way circumgalactic Medium

Anjali Gupta, Joshua Kingsbury, Smita Mathur +4

We analyzed Suzaku and Chandra observations of the soft diffuse X-ray background toward four sightlines with the goal of characterizing the X-ray emission from the Milky Way circum…

Empirical estimates of the Galactic halo contribution to the dispersion measures of extragalactic fast radio bursts using X-ray absorption

Sanskriti Das, Smita Mathur, Anjali Gupta +2

We provide an empirical list of the Galactic dispersion measure () contribution to the extragalactic fast radio bursts along 72 sightlines. It is independent of any model…

Detection of the diffuse HI emission in the Circumgalactic Medium of NGC 891 and NGC 4565

Sanskriti Das, Amy Sardone, Adam K. Leroy +5

We present detections of 21-cm emission from neutral hydrogen (HI) in the circumgalactic medium (CGM) of the local edge-on galaxies NGC 891 and NGC 4565 using the Robert C. Byrd Gr…

The warm-hot, extended, massive circumgalactic medium of NGC 3221: an XMM-Newton discovery

Sanskriti Das, Smita Mathur, Anjali Gupta

Using Suzaku data, we had found a evidence for the X-ray emitting warm-hot circumgalactic medium (CGM) in the L galaxy NGC 3221. Here we present XMM-Newton data and…
