Systematic Study of the Inner Structure of Molecular Tori in Nearby U/LIRGs using Velocity Decomposition of CO Rovibrational Absorption Lines

Shusuke Onishi, Takao Nakagawa, Shunsuke Baba +6

Determining the inner structure of the molecular torus around an active galactic nucleus is essential for understanding its formation mechanism. However, spatially resolving the to…

Warm Molecular Gas in the Central Parsecs of the Buried Nucleus of NGC 4418 Traced with the Fundamental CO Ro-vibrational Absorptions

Youichi Ohyama, Shusuke Onishi, Takao Nakagawa +5

We investigated the inner buried nucleus of a nearby luminous infrared galaxy NGC 4418 using high-resolution spectroscopy of fundamental carbon monoxide (CO) ro-vibrational absorpt…

Probing dynamics and thermal properties inside molecular tori with CO rovibrational absorption lines

Kosei Matsumoto, Takao Nakagawa, Keiichi Wada +5

A recent hydrodynamic model, "radiation-driven fountain model" (Wada et al. 2016), presented a dynamical picture that active galactic nuclei (AGNs) tori sustain their geometrical t…

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…

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…

Chemical and Physical Picture of IRAS 16293-2422 Source B at a Sub-arcsecond Scale Studied with ALMA

Yoko Oya, Kana Moriwaki, Shusuke Onishi +7

We have analyzed the OCS, HCS, CHOH, and HCOOCH data observed toward the low-mass protostar IRAS 16293--2422 Source B at a sub-arcsecond resolution with ALMA. A clear c…
