The Disk Wind Contribution to the Gamma-Ray emission from the nearby Seyfert Galaxy GRS 1734-292

Nobuyuki Sakai, Tomoya Yamada, Yoshiyuki Inoue +4

Radio-quiet Seyfert galaxies have been detected in GeV gamma-rays by the Large Area Telescope (LAT), but the origin of much of this emission is unclear. We consider the nea…

Detection of the [O I] 63 m emission line from the quasar J2054-0005

Nozomi Ishii, Takuya Hashimoto, Carl Ferkinhoff +23

We report the highest-redshift detection of [O I] 63 m from a luminous quasar, J2054-0005, at based on the Atacama Large Millimeter/sub-millimeter Array Band 9 observat…

Deciphering Radio Emissions from Accretion Disk Winds in Radio-Quiet Active Galactic Nuclei

Tomoya Yamada, Nobuyuki Sakai, Yoshiyuki Inoue +1

Unraveling the origins of radio emissions from radio-quiet active galactic nuclei (RQ AGNs) remains a pivotal challenge in astrophysics. One potential source of this radiation is t…

ALMA Confirmation of Millimeter Time Variability in the Gamma-Ray Detected Seyfert Galaxy GRS 1734-292

Tomonari Michiyama, Yoshiyuki Inoue, Akihiro Doi +4

GRS 1734-292 is a radio-quiet galaxy, exhibiting neither intense starburst nor jet activities. However, Fermi-LAT detected this object in the GeV band. The origin of non-thermal ac…

The ALMaQUEST Survey XII: Dense Molecular Gas as traced by HCN and HCO in Green Valley Galaxies

Lihwai Lin, Hsi-An Pan, Sara L. Ellison +11

We present ALMA observations of two dense gas tracers, HCN(1-0) and HCO(1-0), for three galaxies in the green valley and two galaxies on the star-forming main sequence with c…
