Weak-lensing Mass Reconstruction of Galaxy Clusters with a Convolutional Neural Network -- II: Application to Next-Generation Wide-Field Surveys
Sangjun Cha, M. James Jee, Sungwook E. Hong +3
Traditional weak-lensing mass reconstruction techniques suffer from various artifacts, including noise amplification and the mass-sheet degeneracy. In Hong et al. (2021), we demons…
Deeper, Sharper, Faster: Application of Efficient Transformer to Galaxy Image Restoration
Hyosun Park, Yongsik Jo, Seokun Kang +2
The Transformer architecture has revolutionized the field of deep learning over the past several years in diverse areas, including natural language processing, code generation, ima…
Direct Evidence of a Major Merger in the Perseus Cluster
Kim HyeongHan, M. James Jee, Wonki Lee +4
Although the Perseus cluster has often been regarded as an archetypical relaxed galaxy cluster, several lines of evidence including ancient, large-scale cold fronts, asymmetric pla…
Substructures within Substructures in the Complex Post-Merging System A514 Unveiled by High-Resolution Magellan/Megacam Weak Lensing
Eunmo Ahn, M. James Jee, Wonki Lee +2
Abell 514 (A514) at is an intriguing merging system exhibiting highly elongated (~1 Mpc) X-ray features and three large-scale (300~500 kpc) bent radio jets. To dissect th…
SN H0pe: The First Measurement of from a Multiply-Imaged Type Ia Supernova, Discovered by JWST
Massimo Pascale, Brenda L. Frye, Justin D. R. Pierel +21
The first James Webb Space Telescope ({\it JWST}) Near InfraRed Camera (NIRCam) imaging in the field of the galaxy cluster PLCK G165.7+67.0 () uncovered a Type Ia supernova…
