Weak-lensing mass bias in merging galaxy clusters
Wonki Lee, Sangjun Cha, M. James Jee +6
Although weak lensing (WL) is a powerful method to estimate a galaxy cluster mass without any dynamical assumptions, a model bias can arise when the cluster density profile departs…

MARS: A New Maximum Entropy-Regularized Strong Lensing Mass Reconstruction Method
Sangjun Cha, M. James Jee
Free-form strong-lensing (SL) mass reconstructions typically suffer from overfitting, which manifest itself as false-positive small-scale fluctuations. We present a new free-form M…

Weak-lensing Mass Reconstruction of Galaxy Clusters with Convolutional Neural Network
Sungwook E. Hong, Sangnam Park, M. James Jee +2
We introduce a novel method for reconstructing the projected matter distributions of galaxy clusters with weak-lensing (WL) data based on convolutional neural network (CNN). Traini…
