Broad line regions behind haze: Intrinsic shape of Br line and its origin in a type-1 Seyfert galaxy

Keiichi Wada, Tohru Nagao, Taro Shimizu +3

The broad-line region (BLR) of active galactic nuclei (AGN) is an essential component, yet its small size keeps its origin, structure, and kinematics uncertain. Infrared interferom…

Probing AGN Feedback in Dwarf Galaxies with Spatially Resolved NIR Coronal Lines from JWST

Archana Aravindan, Thomas Bohn, Gabriela Canalizo +20

We present the first spatially resolved investigation of near-infrared coronal lines in dwarf galaxies hosting active galactic nuclei (AGN), using JWST/NIRSpec integral field spect…

Black hole accretion, star formation, and chemical evolution with PRIMA/FIRESS spectroscopy: toward the cosmic noon and beyond

Juan Antonio Fernández-Ontiveros, Luigi Spinoglio, Tohru Nagao

The PRobe far-Infrared Mission for Astrophysics (PRIMA) will deliver the first comprehensive view of the obscured side of star formation and black hole accretion that dominates gal…

The connection between galaxy mergers, star formation and AGN activity in the HSC-SSP

Kiyoaki Christopher Omori, Connor Bottrell, Sabine Bellstedt +6

Internal gas inflows driven by galaxy mergers are considered to enhance star formation rates (SFR), fuel supermassive black hole growth and stimulate active galactic nuclei (AGN).…

Systematic Collapse of the Accretion Disc Across the Supermassive Black Hole Population

Scott Hagen, Chris Done, John D. Silverman +7

The structure of the accretion flow onto supermassive black holes (SMBH) is not well understood. Standard disc models match to zeroth order in predicting substantial energy dissipa…

The relationship of SMBHs and host galaxies at in the deep optical variability-selected AGN sample in the COSMOS field

Atsushi Hoshi, Toru Yamada, Mitsuru Kokubo +2

We present the study on the relationship between SMBHs and their host galaxies using our variability-selected AGN sample () constructed from t…
