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 $\si…
ALMA Observations of Multiple-CO and C Lines Toward the Active Galactic Nucleus of NGC 7469: X-Ray-dominated Region Caught in the Act
Takuma Izumi, Dieu D. Nguyen, Masatoshi Imanishi +15
We used the Atacama Large Millimeter/submillimeter Array (ALMA) to map CO( = 1-0), CO( = 2-1), CO( = 3-2), CO( = 2-1), and [CI](-$^3P…
Subaru Infrared Adaptive Optics-assisted High-spatial-resolution Imaging Search for Luminous Dual Active Galactic Nuclei in Nearby Ultraluminous Infrared Galaxies
Masatoshi Imanishi, Taiki Kawamuro, Satoshi Kikuta +2
We present infrared K'- (2.1 micron) and L'-band (3.8 micron) high-spatial-resolution (<0.3") imaging observations of 17 nearby (z < 0.17) ultraluminous infrared galaxies (ULIRGs)…
