Molecular Gas Excitation in z ~ 0.7 Gas-Rich Post-starburst Galaxies from SQuIGGLE

Vincenzo R. D'Onofrio, Justin S. Spilker, Rachel Bezanson +10

Many post-starburst galaxies at have been shown to retain substantial molecular gas reservoirs yet host low ongoing star formation, suggesting that the remaining gas may…

A Possible Protocluster of Galaxies Serendipitously Discovered in the Field of an Intermediate-Redshift Post-starburst Galaxy

Mary C. Knowlton, Justin S. Spilker, Rachel Bezanson +4

We present the serendipitous discovery of an overdensity of submillimeter galaxies (SMGs) in the field of SDSSJ0909-0108, a massive z~0.7 post-starburst galaxy from the SQuIGGLE su…

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…

Unusually High Gas-to-Dust Ratios Observed in High-Redshift Quiescent Galaxies

Justin S. Spilker, Katherine E. Whitaker, Desika Narayanan +15

Tracking the cold molecular gas contents of galaxies is critical to understand the interplay between star formation and galaxy growth across cosmic time. Observations of the long-w…

Meet the Neighbors: Gas Rich "Buddy Galaxies" are Common Around Recently Quenched Massive Galaxies in the SQuIGGE Survey

Anika Kumar, David J. Setton, Rachel Bezanson +7

In this work, we characterize the environments of massive () post-starburst galaxies (PSBs) by studying serendipitously-detected CO(2-1) e…

SQuIGGE: Buried star formation cannot explain the rapidly fading CO(2-1) luminosity in massive, post-starburst galaxies

David J. Setton, Justin S. Spilker, Rachel Bezanson +12

Observational and theoretical studies have long held that rapid gas consumption in starbursts is responsible for the formation of quiescent galaxies. However, studies of recently q…
