Ultra-Diffuse Galaxies (UDGs) with Hyper Suprime-Cam I: Revised Catalog of Coma Cluster UDGs
Jose Miguel Bautista, Jin Koda, Masafumi Yagi +2
This is the first in a series of papers on the properties of ultra-diffuse galaxies (UDGs) in clusters of galaxies. We present an updated catalog of UDGs in the Coma cluster using…
The mag dip in the galaxy luminosity function of Hickson Compact Groups
Hitomi Yamanoi, Masafumi Yagi, Yutaka Komiyama +1
We present the galaxy luminosity functions (LFs) of four Hickson Compact Groups using image data from the Subaru Hyper Suprime-Cam. A distinct dip appeared in the faint-ends of all…
Approximately A Thousand Ultra Diffuse Galaxies in the Coma cluster
Jin Koda, Masafumi Yagi, Hitomi Yamanoi +1
We report the discovery of 854 ultra diffuse galaxies (UDGs) in the Coma cluster using deep R band images, with partial B, i, and Halpha band coverage, obtained with the Subaru tel…
The Galaxy Luminosity Functions down to M_R=-10 in the Coma Cluster
Hitomi Yamanoi, Yutaka Komiyama, Masafumi Yagi +6
We derived the luminosity function (LF) of dwarf galaxies in the Coma Cluster down to M_R=-10 at three fields located at the center, intermediate, and outskirt. The LF (-19<M_R<-10…
