Low Metallicity Gas on the Outskirts of the Local Group: the Circumgalactic Medium of Sextans B
Andrew J. Fox, Sapna Mishra, Frances H. Cashman +6
We present a UV absorption-line analysis of the circumgalactic medium (CGM) of Sextans B, a dwarf irregular galaxy at 1.3 Mpc distance on the outer frontier of the Local Group. Usi…

On the incidence of weak and strong Mg II absorbers towards the Flat and Steep Spectrum Radio quasars
Ritish Kumar, Sapna Mishra, Hum Chand
The incidence rate of Mg II absorbers per unit redshift path (dN/dz) towards quasar sightlines has been used to probe the interaction between quasar jets and surrounding gas clouds…

The Distance to the Magellanic Stream: Constraints from Optical Absorption along Stellar Sightlines
Sapna Mishra, Andrew J. Fox, J. V. Smoker +2
The Magellanic Stream (MS) is a large tail of neutral and ionized gas originating from tidal and hydrodynamical interactions between the Magellanic Clouds as they orbit the Milky W…
