Evolution of Stellar-to-Halo Mass Ratio at z=0-7 Identified by Clustering Analysis with the Hubble Legacy Imaging and Early Subaru/Hyper Suprime-Cam Survey Data
Yuichi Harikane, Masami Ouchi, Yoshiaki Ono +15
We present clustering analysis results from 10,381 Lyman break galaxies (LBGs) at z~ 4-7, identified in the Hubble legacy deep imaging and new complimentary large-area Subaru/Hyper…
Morphologies of ~190,000 Galaxies at z=0-10 Revealed with HST Legacy Data II. Evolution of Clumpy Galaxies
Takatoshi Shibuya, Masami Ouchi, Mariko Kubo +1
We investigate evolution of clumpy galaxies with the Hubble Space Telescope (HST) samples of ~17,000 photo-z and Lyman break galaxies at z~0-8. We detect clumpy galaxies with off-c…
Very Compact Dense Galaxy Overdensity with δ ~ 130 Identified at z ~ 8: Implications for Early Protocluster and Cluster-Core Formation
Masafumi Ishigaki, Masami Ouchi, Yuichi Harikane
We report the first identification of a compact dense galaxy overdensity at dubbed A2744z8OD. A2744z8OD consists of eight -dropout galaxies behind Abell 2744 that is or…
Morphologies of ~190,000 Galaxies at z=0-10 Revealed with HST Legacy Data I. Size Evolution
Takatoshi Shibuya, Masami Ouchi, Yuichi Harikane
We present redshift evolution of galaxy effective radius r_e obtained from the HST samples of ~190,000 galaxies at z=0-10. Our HST samples consist of 176,152 photo-z galaxies at z=…
