SHELLQs. Black Hole Mass and Eddington Ratio Distributions of Intermediate-Luminosity Quasars at 6<z<7

Masafusa Onoue, John D. Silverman, Yoshiki Matsuoka +31

We present near-infrared spectroscopy of 21 quasars at 6.07 < z < 6.90 obtained with JWST/NIRSpec and Subaru/MOIRCS. These targets have absolute ultraviolet magnitudes of -25 < M_1…

SERENADE III: Insight into the Origin of the High Dust Temperature and High [O III]/[C II] Ratio at

Ikki Mitsuhashi, Yuichi Harikane, Hiddo S. B. Algera +10

We present an analysis of ALMA high-frequency observations of nine bright Lyman-break galaxies at . Our sample consists of five galaxies at newly obs…

Discovery of four Narrow-line Type-1 Quasars at z = 2.54 -- 6.06 with Subaru 'Onohi'ula PFS-SSP

Ayumi Takahashi, Yoshiki Matsuoka, Yoshiki Toba +21

We report the discovery of four narrow-line type-1 quasars (NLQ1s) from the Subaru 'Onohi'ula Prime Focus Spectrograph Subaru Strategic Program (PFS-SSP). To extend a comprehensive…

Subaru High- Exploration of Low-Luminosity Quasars (SHELLQs). XXV. Large-scale environments of low-luminosity quasars at traced by Ly emitters

Junya Arita, Nobunari Kashikawa, Yoshiki Matsuoka +18

High- quasars are believed to reside in massive dark matter haloes (DMHs), suggesting that they reside in galaxy overdense regions. However, previous observations have shown a r…

MAJORS II: HCO+& HCN Abundances in W40

René Plume, David J. Eden, Malcolm J. Currie +34

We present observations of HCN and HCO J = in the central region of the W40 massive star forming region. The observations were taken as part of a p…
