The Subaru HSC Galaxy Clustering with Photometric Redshift I: Dark Halo Masses Versus Baryonic Properties of Galaxies at 0.3<z<1.4

Shogo Ishikawa, Nobunari Kashikawa, Masayuki Tanaka +8

We present the clustering properties of low- galaxies selected by the Hyper Suprime-Cam Subaru Strategic Program Wide layer over deg. The wide-field and…

Obscuring fraction of active galactic nuclei implied by supernova and radiative feedbacks

Nozomu Kawakatu, Keiichi Wada, Kohei Ichikawa

We study the obscuring structure of circumnuclear disks (CNDs) by considering supernova (SN) feedbacks from nuclear starburst and the effect of anisotropic radiative pressure from…

The BAT AGN Spectroscopic Survey -- XVIII. Searching for Supermassive Black Hole Binaries in the X-rays

Tingting Liu, Michael Koss, Laura Blecha +15

Theory predicts that a supermassive black hole binary (SMBHB) could be observed as a luminous active galactic nucleus (AGN) that periodically varies on the order of its orbital tim…

Tracing the co-evolution path of super massive black holes and spheroids with AKARI-selected ultra-luminous IR galaxies at intermediate redshifts

Xiao-Yang Chen, Masayuki Akiyama, Kohei Ichikawa +6

We present the stellar population and ionized-gas outflow properties of ultra-luminous IR galaxies (ULIRGs) at 0.1-1.0, which are selected from AKARI FIR all-sky survey. We co…

Amateur telescopes discover a kilometre-sized Kuiper belt object from stellar occultation

K. Arimatsu, K. Tsumura, F. Usui +7

Kuiper belt objects (KBOs) are thought to be the remnant of the early solar system, and their size distribution provides an opportunity to explore the formation and evolution of th…

NuSTAR Discovery of Dead Quasar Engine in Arp 187

Kohei Ichikawa, Taiki Kawamuro, Megumi Shidatsu +7

Recent active galactic nucleus (AGN) and quasar surveys have revealed a population showing rapid AGN luminosity variability by a factor of . Here we present the most drasti…
