Subaru High- Exploration of Low-luminosity Quasars (SHELLQs). XVII. Black Hole Mass Distribution at Estimated via Spectral Comparison with Low- Quasars

Ayumi Takahashi, Yoshiki Matsuoka, Masafusa Onoue +9

We report the distribution of black hole (BH) masses and Eddingont ratios estimated for a sample of 131 low luminosity quasars in the early cosmic epoch (). Our work…

A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). IX. The Most Overdense Region at z~5 Inhabited by a Massive Radio Galaxy

Hisakazu Uchiyama, Takuji Yamashita, Tohru Nagao +13

We report on the galaxy density environment around a high-z radio galaxy (HzRG) at z=4.72, HSC J083913.17+011308.1 (HSC J0839+0113), probed using an r-dropout Lyman break galaxy (L…

A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). VI. Distant Filamentary Structures Pointed by High-z Radio Galaxies at z~4

Hisakazu Uchiyama, Takuji Yamashita, Jun Toshikawa +13

We present the environmental properties around high- radio galaxies (HzRGs) at , which have been poorly investigated because of their rarity. We use the largest samples…

Measuring the Hubble Constant Near and Far in the Era of ELT's

Rachael L. Beaton, Simon Birrer, Ian Dell'Antonio +7

Many of the fundamental physical constants in Physics, as a discipline, are measured to exquisite levels of precision. The fundamental constants that define Cosmology, however, are…

A Double-lined M-dwarf Eclipsing Binary from CSSxSDSS

Chien-Hsiu Lee

Eclipsing binaries offer a unique opportunity to determine basic stellar properties. With the advent of wide-field camera and all-sky time-domain surveys, thousands of eclipsing bi…
