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…
Tracing Radio AGN-Driven Quenching in Post-Starburst Galaxies at Cosmic Noon
Pallavi Patil, Kate Rowlands, Katherine Alatalo +14
We present a radio continuum study of photometrically selected cosmic noon (0.5<z<3) post-starburst galaxies (PSBs) in the UKIDSS Deep Survey (UDS) field to assess if radio-mode Ac…
Galactic Rain: Cool Gas Inflows in Red Geyser Galaxies and Their Connection to AGN Activity and Interactions
Arian Moghni, Namrata Roy, Timothy M. Heckman +3
Red geysers are a population of massive (log[M/M]~10.5), quiescent galaxies that exhibit large-scale but weak, bi-symmetric ionized gas outflows, interpreted as signatures…
A Multiwavelength Evaluation of AGN in the Post-Starburst Phase
Yuanze Luo, Kate Rowlands, Katherine Alatalo +14
The quenching of star formation is a crucial phase in galaxy evolution. Although active galactic nuclei (AGN) feedback has been proposed as a key driver of this transition, the lac…
Clumpy, dense gas in the outflow of NGC 1266
Justin Atsushi Otter, Katherine Alatalo, Kate Rowlands +23
Outflows are one of the most spectacular mechanisms through which active galactic nuclei (AGN) impact their host galaxy, though the role of AGN-driven outflows in global star forma…
Lyman Continuum leakage from massive leaky starbursts: A different class of emitters?
Namrata Roy, Timothy Heckman, Alaina Henry +11
The origin of Lyman Continuum (LyC) photons responsible for reionizing the universe remains a mystery, with the fraction of escaping LyC photons from galaxies at z 6 to 12 be…
