Jet Forecast: Timing of Discrete Jet Ejections of Stellar-Mass Black Holes Anticipated via X-ray Properties
Toshihiro Kawaguchi, Kazutaka Yamaoka
The radio -- soft -ray data of the Galactic black hole binary XTE J1859+226 showed that discrete jets are launched when the inner radius of the accretion disk () rap…
Black hole mass and Eddington ratio distributions of less-luminous quasars at in the Subaru Hyper Suprime-Cam Wide field
Wanqiu He, Masayuki Akiyama, Motohiro Enoki +11
We investigate the black hole mass function (BHMF) and Eddington ratio distribution function (ERDF) of broad-line AGNs at z=4, based on a sample of 52 quasars with i<23.2 at 3.50 <…
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…
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-…
EMPRESS. XIV. Strong High Ionization Lines of Young Galaxies at : Ionizing Spectra Consistent with the Intermediate Mass Black Holes with
Shun Hatano, Masami Ouchi, Hiroya Umeda +16
We present ionizing spectra estimated at 13.6--100 eV for ten dwarf galaxies with strong high ionization lines of He {\sc {ii}}4686 and [Ne {\sc{v}}]3426 ([Ne {\sc{iv}}]24…
Morphological asymmetries of quasar host galaxies with Subaru Hyper Suprime-Cam
Shenli Tang, John D. Silverman, Hassen M. Yesuf +7
How does the host galaxy morphology influence a central quasar or vice versa? We address this question by measuring the asymmetries of 2424 SDSS quasar hosts at using b…
