ALMA Chemical Evolution (ACE) survey: an overview -- extending dust and gas inference to low metallicities at cosmic noon
Irene Shivaei, Gergő Popping, Leindert A. Boogaard +13
The baryon cycle governs the exchange of gas, metals, and dust between galaxies and their environments, but simultaneous constraints on these constituents remain scarce beyond z~1.…
ALMA Chemical Evolution (ACE) Survey: Molecular gas properties of low-mass, low-metallicity galaxies at cosmic noon
Gergő Popping, Ivanna Langan, Nikki N. Geesink +13
Molecular gas plays a central role in regulating star formation and galaxy evolution, yet observational constraints at cosmic noon remain biased toward massive, metal-rich systems.…

Calibrating Photometric Mid-Infrared Star Formation Rates for JWST
Stacey Alberts, George H. Rieke, Irene Shivaei +13
The mid-infrared (IR) spectrum of galaxies has a long history as a valuable proxy for the dust-obscured star formation rate (SFR) in massive galaxies. Now, with JWST, we can explor…
Balmer Decrements and Nebular-Stellar Reddening in JADES Galaxies at
Shreya Karthikeyan, Leonardo Clarke, Alice E. Shapley +5
We aim to characterize nebular and stellar reddening in star-forming galaxies as a function of global galaxy properties (stellar mass, SFR, metallicity) at . We also…
FRESCO: Constraining Dust Attenuation and Star-Formation Rates of Star-Forming Galaxies with JWST Paschen and Ground-Based Balmer Emission Line Observations
Michael A. Wozniak, Naveen A. Reddy, Pascal A. Oesch +7
We present new constraints on dust attenuation and star-formation rates (SFRs) for 77 galaxies at redshifts , using Paschen emission line detections from the JWST FRES…
A JWST Paschen-alpha Calibration of the Radio Luminosity-Star Formation Rate Relation at z~1.3
Nick Seymour, Catherine Hale, Imogen Whittam +17
As radio emission from normal galaxies is a dust-free tracer of star formation, tracing the star formation history of the Universe is a key goal of the SKA and ngVLA. In order to i…
