A CNN--Transformer Denoiser for low- Galaxy Spectra: Stellar Population Recovery in Synthetic Tests
Suk Kim, Joon Hyeop Lee, Soo-Chang Rey
Stellar population measurements in integral field unit surveys are often limited by low signal-to-noise ratios (S/N) in low-surface-brightness spaxels. Using controlled synthetic e…
Molecular Gas and Star Formation in Dwarf Galaxies Observed by the Atacama Large Millimeter/submillimeter Array
Kijeong Yim, Soo-Chang Rey
We present a spatially resolved analysis of the molecular star formation law (SFL) and gravitational instability in a sample of nearby dwarf galaxies (NGC 1035, NGC 4310, NGC 4451,…
Formation Pathways of Compact Elliptical Galaxies: Perspective of Internal Structures
Jinwon Yi, Soo-Chang Rey, Suk Kim +1
We present a structural analysis of 138 compact elliptical galaxies (cEs) in the redshift range of using the Sloan Digital Sky Survey (SDSS) DR12 data. We perform single…
Evidence for Mass-dependent Evolution of Transitional Dwarf Galaxies in the Virgo Cluster
Suk Kim, Soo-Chang Rey, Youngdae Lee
We present a study on the evolution of transitional dwarf galaxies, specifically dwarf lenticulars (dS0s) and early-type dwarfs with blue cores (ETdG(bc)s), driven by environmental…
