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…
Circumnuclear Multi-phase Gas in the Circinus Galaxy. VI. Detectability of Molecular Inflow and Atomic Outflow
Shunsuke Baba, Keiichi Wada, Takuma Izumi +2
Recent submillimeter observations have revealed signs of pc-scale molecular inflow and atomic outflow in the nearest Seyfert 2 galaxy, the Circinus galaxy. To verify the gas kinema…
Self-consistent dust and non-LTE line radiative transfer with SKIRT
Kosei Matsumoto, Peter Camps, Maarten Baes +4
We introduce Monte Carlo-based non-LTE line radiative transfer calculations in the 3D dust radiative transfer code SKIRT, which was originally set up as a dust radiative transfer c…
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…
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…
