Measures the size-mass relation of low-mass quiescent galaxies in a cluster, suggesting their formation history is influenced by environmental factors.
Key Points
The aim is to quantify the structures of low-mass quiescent galaxies in the A2744 galaxy cluster and understand their formation histories.
Analyzed spectrophotometric data from UNCOVER and MegaScience programs using JWST imaging.
Assessed the size-mass relation of low-mass quiescent galaxies in the z=0.308 A2744 cluster.
Compared the size-mass relation in cluster galaxies to similar-redshift field samples.
Identified a higher scatter in the size-mass relation for quiescent galaxies compared to field samples.
Observed that older low-mass quiescent galaxies tend to be more spheroidal.
Implied that quenching and formation of these galaxies occurs at z < 1.5.
