The DAWN JWST Archive: A spectroscopically-informed population study of the physical properties of galaxies at z>2

Rashmi Gottumukkala, Gabriel Brammer, Sune Toft +30

Charting the evolution of star-formation, stellar mass and dust build-up over cosmic time relies on the accurate characterisation of the stellar population properties of high redsh…

Caught Napping by JWST UNCOVER+MegaScience: Constraining bursty star formation histories and number densities of mini-quenched galaxies at redshifts 4-7

Gourav Khullar, Rachel Bezanson, Katherine A. Suess +27

We explore the prevalence of mini-quenched or ``napping'' galaxies selected from spectroscopic and photometric samples in the UNCOVER/MegaScience survey. These galaxies are empiric…

A PANORAMIC of UV-optical morphologies of "Little Red Dots": Two groups of LRDs distinguished by UV half-light radius

Aidan P. Cloonan, Katherine E. Whitaker, Sinclaire M. Manning +13

Among the most remarkable results from JWST is the discovery of abundant, compact, and very red sources in the early Universe known as "Little Red Dots" (LRDs). The relative degree…

Everything Every Band All at Once II: The Relationship Between Optical Size and Stellar Mass Over Eight Billion Years of Cosmic History

Tim B. Miller, Yunchong Zhang, Sedona H. Price +24

While the size-mass relation provides insight into the structural evolution of galaxies, the data available and methods employed have hindered our ability to study a detailed and c…

Where Galaxies Go to Die: The Environments of Massive Quiescent Galaxies at

Ian McConachie, Anna de Graaff, Michael V. Maseda +25

At low redshift, massive quiescent galaxies (MQGs) are most frequently found in massive, rich galaxy clusters, but at high redshift the trend is less clear. Here, we present spectr…

Quenching Through Tidal Gas Removal: Molecular Gas and Star Formation in Tidal Tails of z ~ 0.7 Post-Starburst Galaxies

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

The active suppression of star formation in galaxies is critical in preventing the growth of overly massive systems and explaining the formation of present-day elliptical galaxies.…

Cold gas in a post-starburst pair at z ~ 1.4: major mergers as a pathway to quenching in the HeavyMetal survey

Katherine A. Suess, Aliza G. Beverage, Mariska Kriek +12

Recent observations at low redshift have revealed that some post-starburst galaxies retain significant molecular gas reservoirs despite low ongoing star formation rates, challengin…

UNCOVER/MegaScience: No Evidence of Environmental Quenching in a z2.6 Proto-cluster

Richard Pan, Katherine A. Suess, Danilo Marchesini +22

Environmental quenching -- where interactions with other galaxies and/or the intra-cluster medium (ICM) suppress star formation in low-mass galaxies -- has been well-established as…

A confirmed deficit of hot and cold dust emission in the most luminous Little Red Dots

David J. Setton, Jenny E. Greene, Justin S. Spilker +33

Luminous broad H emission and red rest-optical SEDs are the hallmark of compact Little Red Dots (LRDs), implying highly attenuated dusty starbursts and/or obscured active galact…
