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…
Angular momentum evolution of stellar disks at high redshifts
Taku Okamura, Kazuhiro Shimasaku, Ryota Kawamata
The stellar disk size of a galaxy depends on the ratio of the disk stellar mass to the halo mass, , and the fraction of the dark halo angular mom…
Two Peculiar Fast Transients in a Strongly Lensed Host Galaxy
S. A. Rodney, I. Balestra, M. Bradac +32
A massive galaxy cluster can serve as a magnifying glass for distant stellar populations, with strong gravitational lensing exposing details in the lensed background galaxies that…
Extreme magnification of a star at redshift 1.5 by a galaxy-cluster lens
Patrick L. Kelly, Jose M. Diego, Steven Rodney +42
Galaxy-cluster gravitational lenses can magnify background galaxies by a total factor of up to ~50. Here we report an image of an individual star at redshift z=1.49 (dubbed "MACS J…
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…
