Astrophysical calibration of the oscillator strengths of YJ-band absorption lines in classical Cepheids
S. S. Elgueta, N. Matsunaga, M. Jian +13
Newly-developed spectrographs with increased resolving powers, particularly those covering the near-IR range, allow the characterization of more and more absorption lines in stella…
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-…
Narrow Fe-K Reverberation Mapping Unveils the Deactivated Broad-Line Region in a Changing-Look Active Galactic Nucleus
Hirofumi Noda, Taisei Mineta, Takeo Minezaki +11
"Changing-look active galactic nuclei" (CLAGNs) are known to change their apparent types between types 1 and 2, usually accompanied by a drastic change in their luminosity on times…
Measurement of AGN dust extinction based on the near-infrared flux variability of WISE data
Shoichiro Mizukoshi, Takeo Minezaki, Shoichi Tsunetsugu +4
We present the measurement of the line-of-sight extinction of the dusty torus for a large number of obscured active galactic nuclei (AGNs) based on the reddening of the colour of t…
Potential signature of Population III pair-instability supernova ejecta in the BLR gas of the most distant quasar at z = 7.54
Yuzuru Yoshii, Hiroaki Sameshima, Takuji Tsujimoto +3
The search for Population III (Pop III) stars has fascinated and eluded astrophysicists for decades. One promising place for capturing evidence of their presence must be high-redsh…
Survey of near-infrared diffuse interstellar bands in and bands. I. Newly identified bands
Satoshi Hamano, Naoto Kobayashi, Hideyo Kawakita +12
We searched for diffuse interstellar bands (DIBs) in the 0.911.33 m region by analyzing the near-infrared (NIR) high-resolution ( and 28,000) spectra of 31 redden…
