Extremely Buried Nucleus of IRAS 172080014 Observed at Sub-Millimeter and Near-Infrared Wavelengths
Shunsuke Baba, Masatoshi Imanishi, Takuma Izumi +6
The ultraluminous infrared galaxy IRAS 172080014 is a late-stage merger that hosts a buried active galactic nucleus (AGN). To investigate its nuclear structure, we performed hig…
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)…
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…
