JWST/NIRSpec Reveals Diverse Nuclear Environments in Dwarf Galaxies Hosting AGN

Thomas Bohn, Archana Aravindan, Gabriela Canalizo +18

Dwarf galaxies, in the CDM framework, are expected to dominate the galaxy number density at all redshifts. As such, studying AGN in these systems, including characterizing their…

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).…

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…

Multi-phase gas nature in the sub-pc region of the active galactic nuclei II: Possible origins of the changing-state AGNs

Keiichi Wada, Yuki Kudoh, Tohru Nagao

Multi-wavelength observations of active galactic nuclei (AGNs) often reveal various time scales of variability. Among these phenomena, "changing-look AGNs" are extreme cases where…

EMPRESS. IX. Extremely Metal-Poor Galaxies are Very Gas-Rich Dispersion-Dominated Systems: Will JWST Witness Gaseous Turbulent High-z Primordial Galaxies?

Yuki Isobe, Masami Ouchi, Kimihiko Nakajima +49

We present kinematics of 6 local extremely metal-poor galaxies (EMPGs) with low metallicities () and low stellar masses (). Tak…

Near-infrared spectroscopy of nearby Seyfert galaxies: Is there evidence for the shock excitation in narrow-line regions?

Koki Terao, Tohru Nagao, Tetsuya Hashimoto +5

One of the unsettled, important problems in active galactic nuclei (AGNs) is the major ionization mechanism of gas clouds in their narrow-line regions (NLRs). In order to investiga…

A higher efficiency of converting gas to stars push galaxies at z ~ 1.6 well above the star-forming main sequence

J. D. Silverman, E. Daddi, G. Rodighiero +18

Local starbursts have a higher efficiency of converting gas into stars, as compared to typical star-forming galaxies at a given stellar mass, possibly indicative of different modes…
