We present the statistical redshift distribution of a large sample of low surface brightness (LSB) galaxies identified in the first 200 deg of the Hyper Suprime-Cam Strategic S…
SDSS-IV MaNGA: Cannibalism Caught in the Act -- on the Frequency of Occurrence of Multiple Cores in Brightest Cluster Galaxies
Yun-Hsin Hsu, Yen-Ting Lin, Song Huang +16
Although it is generally accepted that massive galaxies form in a two-phased fashion, beginning with a rapid mass buildup through intense starburst activities, followed by primaril…
Ultra-Diffuse Galaxies in the Perseus Cluster: Comparing Galaxy Properties with Globular Cluster System Richness
Jonah S. Gannon, Duncan A. Forbes, Aaron J. Romanowsky +6
It is clear that within the class of ultra-diffuse galaxies (UDGs) there is an extreme range in the richness of their associated globular cluster (GC) systems. Here, we report the…
Reaching for the Edge I: Probing the Outskirts of Massive Galaxies with HSC, DECaLS, SDSS, and Dragonfly
Jiaxuan Li, Song Huang, Alexie Leauthaud +9
The outer light (stellar halos) of massive galaxies has recently emerged as a possible low scatter tracer of dark matter halo mass. To test the robustness of outer light measuremen…
