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…
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…
Formation pathways of the compact stellar systems
J. K. Jang, Sukyoung K. Yi, Soo-Chang Rey +6
The formation pathways of compact stellar systems (CSSs) are still under debate. We utilize the \NH\ simulation to investigate the origins of such objects in the field environment.…
Similar image retrieval using Autoencoder. I. Automatic morphology classification of galaxies
Eunsuk Seo, Suk Kim, Youngdae Lee +4
We present the construction of an image similarity retrieval engine for the morphological classification of galaxies using the Convolutional AutoEncoder (CAE). The CAE is trained o…
Witnessing a Transformation to Blue-cored Dwarf Early-type Galaxies in Filaments and the Cluster Outskirts: Gas-phase Abundances and Internal Kinematics Perspectives
Jiwon Chung, Joon Hyeop Lee, Hyunjin Jeong +1
The presence of transitional dwarf galaxies in filaments and cluster outskirts may be closely related to pre-processing in the filament; however, the underlying mechanism is not ye…
