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…

SN H0pe: The First Measurement of $H_{0}$ 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 ( $z = 0.35$ ) uncovered a Type Ia supernova…
