Size--luminosity relations and UV luminosity functions at simultaneously derived from the complete Hubble Frontier Fields data
Ryota Kawamata, Masafumi Ishigaki, Kazuhiro Shimasaku +3
We construct , 8, and 9 faint Lyman break galaxy samples (334, 61, and 37 galaxies, respectively) with accurate size measurements with the software from…
Full-Data Results of Hubble Frontier Fields: UV Luminosity Functions at and a Consistent Picture of Cosmic Reionization
Masafumi Ishigaki, Ryota Kawamata, Masami Ouchi +3
We present UV luminosity functions of dropout galaxies at with the complete Hubble Frontier Fields data. We obtain a catalog of dropout-galaxy candidates (350…
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…
Precise Strong Lensing Mass Modeling of Four Hubble Frontier Fields Clusters and a Sample of Magnified High-Redshift Galaxies
Ryota Kawamata, Masamune Oguri, Masafumi Ishigaki +2
We conduct precise strong lensing mass modeling of four Frontier Fields (HFF) clusters, Abell2744, MACSJ0416.12403, MACSJ0717.53745, and MACSJ1149.…
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…
ALMA Census of Faint 1.2 mm Sources Down to ~0.02 mJy: Extragalactic Background Light and Dust-Poor High-z Galaxies
Seiji Fujimoto, Masami Ouchi, Yoshiaki Ono +4
We present statistics of 133 faint 1.2-mm continuum sources detected in about 120 deep ALMA pointing data that include all the archival deep data available by 2015 June. We derive…
The sizes of lensed galaxies from the Hubble Frontier Fields Abell 2744 data
Ryota Kawamata, Masafumi Ishigaki, Kazuhiro Shimasaku +2
We investigate sizes of dropout galaxies using the complete data of the Abell 2744 cluster and parallel fields in the Hubble Frontier Fields program. By directly fitting…
Hubble Frontier Fields First Complete Cluster Data: Faint Galaxies at for UV Luminosity Functions and Cosmic Reionization
Masafumi Ishigaki, Ryota Kawamata, Masami Ouchi +3
We present the comprehensive analyses of faint dropout galaxies up to with the first full-depth data set of Abell 2744 lensing cluster and parallel fields observed by the…
