Discovery of a Barred-Spiral Galaxy at = 3.16 II. The Star Formation History
Yingjie Cheng, Mauro Giavalisco, Daniel Ivanov +6
We present a detailed analysis of a massive barred galaxy at using deep multi-band imaging from HST and JWST. For the first time, we resolve its morphology and st…
Toward Unbreaking the Universe: MINERVA Measurements of Color Gradients in Massive Quiescent Galaxies Can Help Ease Too-Early Star Formation Tensions
Sam E. Cutler, Luke Robbins, Danilo Marchesini +41
The discovery of a population of massive, ancient quiescent galaxies within the first 2 Gyr of the Universe's history has led to significant tensions with models of galaxy formatio…
JWST Observations of Starbursts: Dust Processing in the M82 Superwind
Serena A. Cronin, Alberto D. Bolatto, Helena M. Richie +39
We present JWST MIRI and NIRCam imaging of the inner ~5 kpc of the M82 superwind at 0.05-0.375'' (~0.9-6.5 pc) resolution. Targeted filters probe emission from polycyclic aromatic…
Everything Every Band All at Once I: A Global Morphology Catalog in Abell 2744 based on UNCOVER/MegaScience
Yunchong Zhang, Tim B. Miller, Sedona H. Price +31
We present spectrally-resolved structural parameter measurements of 28,274 sources from the legacy lensing field of Abell 2744, quantifying global structures from observed $0.7 μm…
Highly Efficient Selection of High-Redshift Emission-Line Galaxies for future DESI-like surveys with Deep Multi-band Imaging
Yoquelbin Salcedo Hernandez, Jeffrey A. Newman, Brett. H. Andrews +53
Emission-line galaxies (ELGs) are an important tracer of baryon acoustic oscillations (BAO) and large-scale structure (LSS) at . In this work, we investigate the feasibility…
Hidden mass in early galaxies revealed by bottom-heavy initial mass functions
Chloe M. Cheng, Martje Slob, Mariska Kriek +21
James Webb Space Telescope (JWST) observations have revealed that massive galaxies formed and evolved faster than predicted by galaxy formation models, with many having already ass…
