SQuIGGLE: Radio AGN Found Predominantly in Young, Gas-rich Post-starburst Galaxies at z ~ 0.7
Vincenzo R. D'Onofrio, Justin S. Spilker, Krista L. Smith +13
The processes that rapidly quench massive galaxies and maintain their quiescence remain poorly understood. Substantial molecular gas reservoirs can survive this shutdown in post-st…
Extreme MgII Emission in Recently-Quenched Galaxies: A New Sample of Intermediate-Redshift Post-Starburst Quasars from the DESI Early Data Release
Margaret E. Verrico, Aayan Verma, K. Decker French +8
Post-starburst galaxies are galaxies which have recently and rapidly shut off star formation. AGN activity is often invoked to explain this rapid quenching, but most post-starburst…
SQuIGGE: Ubiquitous Cool Gas Outflows with Large Mass-Loading Factors in Post-starburst Galaxies
Yuanze Luo, Justin S. Spilker, David J. Setton +13
While recent James Webb Space Telescope studies have highlighted cool gas outflows as an important mechanism for rapid quenching at , such space-based spectroscopic samp…
SQuIGGE: Spatially resolved NIRSpec Pa reveals that the most CO-luminous, post-starburst galaxies exhibit falling---but still active---star formation behind optically thick dust
David J. Setton, Jenny E. Greene, Rachel Bezanson +13
One of the fundamental uncertainties in the study of galaxies at the interface between star formation and quiescence--post-starburst galaxies--is their instantaneous star formation…
The Delay Time Distribution of Quasi-Periodic Eruptions
Margaret Shepherd, K. Decker French, Jason T. Hinkle +4
Quasi-periodic eruptions (QPEs) are quasi-periodic X-ray bursts observed in the nucleus of a galaxy. Multiple pieces of observational evidence link QPEs to tidal disruption events…
Identifying Changing-Look AGN Transitions in Light Curve Data with the Zwicky Transient Facility
Margaret E. Verrico, K. Decker French, Vivienne F. Baldassare +10
Changing-Look AGN (CL-AGN) are AGN which transition between Seyfert types, challenging AGN unification models. Most CL-AGN have been identified via repeat spectroscopy, making it d…
The Delay Time Distribution of Tidal Disruption Events
Margaret Shepherd, K. Decker French, Nicholas C. Stone +6
Tidal disruption events (TDEs) can be observed when stars get too close to supermassive black holes and are torn apart and accreted. The delay time distribution of TDEs, or rate of…
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…
Selecting Post-Starburst Galaxies Based on Star Formation History
Sara Starecheski, K. Decker French, Vicente Villanueva +6
Post-StarBurst (PSB) galaxies are galaxies that have undergone a large burst of star formation followed by rapid quenching. Understanding their properties as a population can help…
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…
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…
Radio Variability in Recently-Quenched Galaxies: The Impact of TDE or AGN Driven Outflows
K. Decker French, Kristina Nyland, Pallavi Patil +7
Outflows and jets launched from the nuclei of galaxies emit radio synchrotron emission that can be used to study the impact of accretion energy on the host galaxy. The decades-long…
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…
Modeling Star Formation Histories of Changing-Look AGN Host Galaxies with Prospector
Margaret E. Verrico, K. Decker French, Katherine Suess +7
Changing-look active galactic nuclei, or CL-AGN, are AGN which appear to transition between Seyfert Type 1 and 2 over periods of months to years. Several mechanisms to trigger thes…
