ALMA Sub-arcsec-resolution 183 GHz H2O and Dense Molecular Line Observations of Nearby Ultraluminous Infrared Galaxies
Masatoshi Imanishi, Kouichiro Nakanishi, Takuma Izumi +1
We present the results of ALMA 2 mm, 1-resolution observations of ten (ultra)luminous infrared galaxies ([U]LIRGs; infrared luminosity 10L$_{…
The MBHBM Project -- II. Molecular Gas Kinematics in the Lenticular Galaxy NGC 3593 Reveal a Supermassive Black Hole
Dieu D. Nguyen, Martin Bureau, Sabine Thater +15
As part of the Measuring Black Holes in Below Milky Way-mass (M) galaxies (MBHBM) Project, we present a dynamical measurement of the supermassive black hole (SMBH)…
Hard X-ray Irradiation Potentially Drives Negative AGN Feedback by Altering Molecular Gas Properties
Taiki Kawamuro, Claudio Ricci, Takuma Izumi +4
To investigate the role of active galactic nucleus (AGN) X-ray irradiation on the interstellar medium (ISM), we systematically analyzed Chandra and ALMA CO(=2-1) data for 26 ult…
Anomalous Hydrogen Recombination-Line Ratios in Ultraluminous Infrared Galaxies
Kenichi Yano, Shunsuke Baba, Takao Nakagawa +5
We conducted systematic observations of the H I Br (4.05 m) and Br (2.63 m) lines in 52 nearby () ultraluminous infrared galaxies (ULIRGs) with AKARI. Among 33 U…
Study of the Inner Structure of the Molecular Torus in IRAS 08572+3915 NW with Velocity Decomposition of CO Rovibrational Absorption Lines
Shusuke Onishi, Takao Nakagawa, Shunsuke Baba +6
Understanding the inner structure of the clumpy molecular torus surrounding the active galactic nucleus is essential in revealing the forming mechanism. However, spatially resolvin…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). XIII. Large-scale Feedback and Star Formation in a Low-Luminosity Quasar at z = 7.07 on the Local Black Hole to Host Mass Relation
Takuma Izumi, Yoshiki Matsuoka, Seiji Fujimoto +22
We present ALMA [CII] 158 m line and underlying far-infrared (FIR) continuum emission observations ( resolution) toward HSC J124353.93010038.5 (J1243…
Circumnuclear Multi-phase Gas in Circinus Galaxy IV: absorption owing to high- CO rotational transitions
Taisei Uzuo, Keiichi Wada, Takuma Izumi +3
We studied the absorption features of CO lines against the continuum originating from the heated dust in the obscuring tori around active galactic nuclei (AGNs). We investigated th…
Black hole mass measurement using ALMA observations of [CI] and CO emissions in the Seyfert 1 galaxy NGC7469
Dieu D. Nguyen, Takuma Izumi, Sabine Thater +11
We present a supermassive black hole (SMBH) mass measurement in the Seyfert 1 galaxy NGC7469 using Atacama Large Millimeter/submillimeter Array (ALMA) observations of the atomic-${…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs) XII. Extended [C II] Structure (Merger or Outflow) in a z = 6.72 Red Quasar
Takuma Izumi, Masafusa Onoue, Yoshiki Matsuoka +31
We present ALMA [C II] 158 m line and far-infrared (FIR) continuum emission observations toward HSC J120505.09000027.9 (J12050000) at with the beam size of $\si…
