PEGASUS (Pfs Emission-line GAlaxy SUrvey with Subaru): I. Three-dimensional large-scale structures at probed with emission-line galaxies

Mariko Kubo, Tadayuki Kodama, Rhythm Shimakawa +16

To comprehensively understand the environmental effects on galaxy evolution, it is crucial to precisely map the distribution and thoroughly examine the properties of galaxies, incl…

Spectropolarimetry of Type II supernovae (I) Sample, observational data and interstellar polarization

T. Nagao, S. Mattila, R. Kotak +1

We investigate polarization spectra of hydrogen-rich core-collapse supernovae (Type~II SNe). The polarization signal from SNe contains two independent components: intrinsic SN pola…

Reconstruction of Cosmic Black Hole Growth and Mass Distribution from Quasar Luminosity Functions at : Implications for Faint and Low-mass Populations in JWST

Wenxiu Li, Kohei Inayoshi, Masafusa Onoue +6

The evolution of the quasar luminosity function (QLF) is fundamental to understanding the cosmic evolution of black holes (BHs) through their accretion phases. In the era of the Ja…

Quasar Luminosity Function at z = 7

Yoshiki Matsuoka, Masafusa Onoue, Kazushi Iwasawa +41

We present the quasar luminosity function (LF) at , measured with 35 spectroscopically confirmed quasars at . The sample of 22 quasars from the Subaru High-…

Supermassive primordial black holes: a view from clustering of quasars at

Takumi Shinohara, Wanqiu He, Yoshiki Matsuoka +3

We investigate a scenario where primordial black holes (PBHs) can be the progenitors of supermassive black holes (SMBHs) observed at . To this end, we carried out clusterin…

Photometry and spectroscopy of the Type Icn supernova 2021ckj: The diverse properties of the ejecta and circumstellar matter of Type Icn SNe

T. Nagao, H. Kuncarayakti, K. Maeda +20

We present photometric and spectroscopic observations of the Type Icn supernova (SN) 2021ckj. Spectral modeling of SN 2021ckj reveals that its composition is dominated by oxygen, c…
