Little Red Dots and Supermassive Black Hole Seed Formation in Ultralight Dark Matter Halos
Dongsu Bak, Jae-Weon Lee
We explore a possible mechanism for the formation of supermassive black hole (SMBH) seeds at the centers of ultralight dark matter (ULDM) halos in the early Universe. We investigat…

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…

Final parsec problem of black hole mergers and ultralight dark matter
Hyeonmo Koo, Dongsu Bak, Inkyu Park +2
When two galaxies merge, they often produce a supermassive black hole binary (SMBHB) at their center. Numerical simulations with stars and cold dark matter show that SMBHBs typical…
