Lighting Up the CGM: Strong, Jet-Aligned Emission around Radio Galaxies
Namrata Roy, Sanchayeeta Borthakur, Timothy Heckman +1
A primary question within galaxy evolution is how active galactic nuclei (AGN) feedback modifies the circumgalactic medium (CGM). We present a search for faint H emission from…

Revealing Cosmic Ecosystems with the Hubble Space Telescope in 2030s and Beyond
Sanchayeeta Borthakur, Tanmay Singh, David French +22
Ultraviolet spectroscopy with the Hubble Space Telescope (HST) provides the most direct and sensitive probe of the disk-circumgalactic medium (CGM) interface at radii of 20 kpc, wh…

Analysis of synthetic OVI absorption associated with galaxy groups in SIMBA and TNG50 simulations
Tanmay Singh, Sanchayeeta Borthakur, Dylan Nelson +2
We compare OVI absorption in synthetic spectra from galaxy groups in the SIMBA and TNG50 cosmological hydrodynamic simulations against those observed from the COS-IGrM survey. We s…
