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…

10 Years of Archival High-Resolution NIR Spectra: The Raw and Reduced IGRINS Spectral Archive (RRISA)

Erica Sawczynec, Kyle F. Kaplan, Gregory N. Mace +20

The Immersion GRating INfrared Spectrometer (IGRINS) is a compact, high-resolution (R~45,000) near-infrared spectrograph spanning 1.45 to 2.45 um in a single exposure. We introduce…

The Seoul National University AGN Monitoring Project III: H lag measurements of 32 luminous AGNs and the high-luminosity end of the size--luminosity relation

Jong-Hak Woo, Shu Wang, Suvendu Rakshit +28

We present the main results from a long-term reverberation mapping campaign carried out for the Seoul National University Active Galactic Nuclei (AGN) Monitoring Project. High-qual…

The Seoul National University AGN Monitoring Project IV: H reverberation mapping of 6 AGNs and the H Size-Luminosity Relation

Hojin Cho, Jong-Hak Woo, Shu Wang +29

The broad line region (BLR) size-luminosity relation has paramount importance for estimating the mass of black holes in active galactic nuclei (AGNs). Traditionally, the size of th…

Exploring the Fundamental Mechanism in Driving Highest-velocity Ionized Outflows in Radio AGNs

Ashraf Ayubinia, Yongquan Xue, Jong-Hak Woo +4

We investigate the ionized gas kinematics relationship with X-ray, radio and accreting properties using a sample of 348 nearby () SDSS-FIRST-X-ray detected AGNs. X-ray pro…

AGN lifetimes in UV-selected galaxies: a clue to supermassive black hole-host galaxy coevolution

Xiaozhi Lin, Yongquan Xue, Guanwen Fang +3

The coevolution between supermassive black holes (SMBHs) and their host galaxies has been proposed for more than a decade, albeit with little direct evidence about black hole accre…
