X-ray study of the double source plane gravitational lens system Eye of Horus observed with XMM-Newton
Keigo Tanaka, Ayumi Tsuji, Hiroki Akamatsu +19
A double source plane (DSP) system is a precious probe for the density profile of distant galaxies and cosmological parameters. However, these measurements could be affected by the…
Survey of Gravitationally-lensed Objects in HSC Imaging (SuGOHI). IV. Lensed quasar search in the HSC survey
James H. H. Chan, Sherry H. Suyu, Alessandro Sonnenfeld +9
Strong gravitationally lensed quasars provide powerful means to study galaxy evolution and cosmology. We use Chitah to hunt for new lens systems in the Hyper SuprimeCam Subaru S…
Lensed quasar search via time variability with the HSC transient survey
Dani C. -Y. Chao, James H. -H. Chan, Sherry H. Suyu +5
Gravitationally lensed quasars are useful for studying astrophysics and cosmology, and enlarging the sample size of lensed quasars is important for multiple studies. In this work,…
Discovery of an unusually compact lensed Lyman Break Galaxy from the Hyper Suprime-Cam Survey
Anton T. Jaelani, Anupreeta More, Alessandro Sonnenfeld +8
We report the serendipitous discovery of HSC J09040102, a quadruply-lensed Lyman break galaxy (LBG) in the Survey of Gravitationally-lensed Objects in Hyper Suprime-Cam Imaging…
Second Data Release of the Hyper Suprime-Cam Subaru Strategic Program
Hiroaki Aihara, Yusra AlSayyad, Makoto Ando +62
This paper presents the second data release of the Hyper Suprime-Cam Subaru Strategic Program, a wide-field optical imaging survey on the 8.2 meter Subaru Telescope. The release in…
Survey of gravitationally-lensed objects in HSC imaging (SuGOHI). III. Statistical strong lensing constraints on the stellar IMF of CMASS galaxies
Alessandro Sonnenfeld, Anton T. Jaelani, James H. H. Chan +5
Context: The determination of the stellar initial mass function (IMF) of massive galaxies is one of the open problems in cosmology. Strong gravitational lensing is one of the few m…
