Investigating Ionization in the Intergalactic Medium
Brad Koplitz, Anjali Ramesh, Sanchayeeta Borthakur
The Intergalactic Medium (IGM) contains 50% of the baryonic mass of the Universe, yet the mechanisms responsible for keeping the IGM ionized has not been fully explained. Hence,…
The Impact of Starbursts on the Circumgalactic Medium
Sanchayeeta Borthakur, Timothy Heckman, David Strickland +2
We present a study exploring the impact of a starburst on the properties of the surrounding circum-galactic medium (CGM): gas located beyond the galaxy's stellar body and extending…
Extreme Feedback and the Epoch of Reionization: Clues in the Local Universe
Timothy M. Heckman, Sanchayeeta Borthakur, Roderik Overzier +8
The source responsible for reionizing the universe at z > 6 remains uncertain. While an energetically adequate population of star-forming galaxies may be in place, it is unknown wh…
A GBT Survey for HI 21 cm Absorption in the Disks and Halos of Low-Redshift Galaxies
Sanchayeeta Borthakur, Todd M. Tripp, Min S. Yun +4
We present an HI 21 cm absorption survey with the Green Bank Telescope (GBT) of galaxy-quasar pairs selected by combining data from the Sloan Digital Sky Survey (SDSS) and the Fain…
Detection of Diffuse Neutral Intragroup Medium in Hickson Compact Groups
Sanchayeeta Borthakur, Min Su Yun, Lourdes Verdes-Montenegro
We present new Green Bank Telescope (GBT) 21 cm neutral hydrogen (HI) observations of a complete distance limited sample of 22 Hickson Compact Groups (HCGs) with at least four true…
Using 21cm Absorption in Small Impact Parameter Galaxy-QSO Pairs to Probe Low-Redshift Damped and Sub-Damped Lyman-alpha System
Sanchayeeta Borthakur, Todd M. Tripp, Min S. Yun +4
To search for low-redshift damped Lyman-alpha (DLA) and sub-DLA quasar absorbers, we have conducted a 21cm absorption survey of radio-loud quasars at small impact parameters to for…
