Subaru Hyper Suprime-Cam excavates colossal over- and under-dense structures over 360 deg2 out to z=1
Rhythm Shimakawa, Yuichi Higuchi, Masato Shirasaki +8
Subaru Strategic Program with the Hyper-Suprime Cam (HSC-SSP) has proven to be successful with its extremely-wide area coverage in past years. Taking advantages of this feature, we…
Halo Concentration, Galaxy Red Fraction, and Gas Properties of Optically-defined Merging Clusters
Nobuhiro Okabe, Masamune Oguri, Hiroki Akamatsu +9
We present multi-wavelength studies of optically-defined merging clusters, based on the Hyper Suprime-Cam Subaru Strategic Program. Luminous red galaxies, tracing cluster mass dist…
Correlation between star formation activity and electron density of ionized gas at z=2.5
Rhythm Shimakawa, Tadayuki Kodama, Charles C. Steidel +7
In the redshift interval of , the physical conditions of the inter-stellar medium (ISM) in star-forming galaxies are likely to be different from those in the local Universe…
Mapping the large scale structure around a z=1.46 galaxy cluster in 3-D using two adjacent narrow-band filters
Masao Hayashi, Tadayuki Kodama, Yusei Koyama +7
We present a novel method to estimate accurate redshifts of star-forming galaxies by measuring the flux ratio of the same emission line observed through two adjacent narrow-band fi…
Nature of H-alpha selected galaxies at z>2. II. Clumpy galaxies and compact star-forming galaxies
Ken-ichi Tadaki, Tadayuki Kodama, Ichi Tanaka +3
We present the morphological properties of 109 Hα-selected galaxies at z>2 in SXDF-UDS-CANDELS field. With high-resolution optical/near-infrared images obtained by Hubble Space Tel…
A fundamental metallicity relation for galaxies at z = 0.84 - 1.47 from HiZELS
John P. Stott, David Sobral, Richard Bower +6
We obtained Subaru FMOS observations of Halpha emitting galaxies selected from the HiZELS narrow-band survey, to investigate the relationship between stellar mass, metallicity and…
