SILVERRUSH. V. Census of Lya, [OIII]5007, Ha, and [CII]158um Line Emission with ~1000 LAEs at z=4.9-7.0 Revealed with Subaru/HSC
Yuichi Harikane, Masami Ouchi, Takatoshi Shibuya +23
We investigate Lya, [OIII]5007, Ha, and [CII]158um emission from 1124 galaxies at z=4.9-7.0. Our sample is composed of 1092 Lya emitters (LAEs) at z=4.9, 5.7, 6.6, and 7.0 identifi…
Minor Contribution of Quasars to Ionizing Photon Budget at z~6: Update on Quasar Luminosity Function at the Faint-end with Subaru/Suprime-Cam
Masafusa Onoue, Nobunari Kashikawa, Chris J. Willott +16
We constrain the quasar contribution to cosmic reionization based on our deep optical survey of z~6 quasars down to z_R=24.15 using Subaru/Suprime-Cam in three UKIDSS-DXS fields co…
Recently Quenched Galaxies at z = 0.2 - 4.8 in the COSMOS UltraVISTA Field
Akie Ichikawa, Yoshiki Matsuoka
We present a new analysis of the stellar mass function and morphology of recently-quenched galaxies (RQGs), whose star formation has been recently quenched for some reason. The COS…
Galaxy Interactions Trigger Rapid Black Hole Growth: an unprecedented view from the Hyper Suprime-Cam Survey
Andy D. Goulding, Jenny E. Greene, Rachel Bezanson +6
Collisions and interactions between gas-rich galaxies are thought to be pivotal stages in their formation and evolution, causing the rapid production of new stars, and possibly ser…
Active Galactic Nucleus Environments and Feedback to Neighboring Galaxies at Probed by Lyman-Alpha Emitters
Satoshi Kikuta, Masatoshi Imanishi, Yoshiki Matsuoka +3
Active galactic nuclei (AGNs) in the high-redshift Universe are thought to reside in overdense environments. However, recent works provide controversial results partly due to the u…
Clustering of quasars in a wide luminosity range at redshift 4 with Subaru Hyper Suprime-Cam wide field imaging
Wanqiu He, Masayuki Akiyama, James Bosch +25
We examine the clustering of quasars over a wide luminosity range, by utilizing 901 quasars at with photometrically se…
The Quasar Luminosity Function at Redshift 4 with Hyper Suprime-Cam Wide Survey
Masayuki Akiyama, Wanqiu He, Hiroyuki Ikeda +24
We present the luminosity function of z=4 quasars based on the Hyper Suprime-Cam Subaru Strategic Program Wide layer imaging data in the g, r, i, z, and y bands covering 339.8 deg^…
Enhancement of Galaxy Overdensity around Quasar Pairs at z<3.6 based on the Hyper Suprime-Cam Subaru Strategic Program Survey
Masafusa Onoue, Nobunari Kashikawa, Hisakazu Uchiyama +12
We investigate the galaxy overdensity around proto-cluster scale quasar pairs at high (z>3) and low (z~1) redshift based on the unprecedentedly wide and deep optical survey of the…
Great Optically Luminous Dropout Research Using Subaru HSC (GOLDRUSH). I. UV Luminosity Functions at Derived with the Half-Million Dropouts on the 100 deg Sky
Yoshiaki Ono, Masami Ouchi, Yuichi Harikane +23
We study the UV luminosity functions (LFs) at , , and based on the deep large-area optical images taken by the Hyper Suprime-Cam (HSC) Subaru strategic program…
The Hyper Suprime-Cam SSP Survey: Overview and Survey Design
H. Aihara, N. Arimoto, R. Armstrong +139
Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of the 8.2m Subaru telescope on the summit of Maunakea in Hawaii. A team of scientists from Japan, Taiwan…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). II. Discovery of 32 Quasars and Luminous Galaxies at 5.7 < z < 6.8
Yoshiki Matsuoka, Masafusa Onoue, Nobunari Kashikawa +43
We present spectroscopic identification of 32 new quasars and luminous galaxies discovered at 5.7 < z < 6.8. This is the second in a series of papers presenting the results of the…
Ultraviolet to optical diffuse sky emission as seen by the Hubble Space Telescope Faint Object Spectrograph
K. Kawara, Y. Matsuoka, K. Sano +5
We present an analysis of the blank sky spectra observed with the Faint Object Spectrograph on board the Hubble Space Telescope. We study the diffuse sky emission from ultraviolet…
