Impact of a binary companion in AGB outflows on CO spectral lines
Owen Vermeulen, Mats Esseldeurs, Jolien Malfait +7
In the late stage of their evolution, low- to intermediate-mass stars pass through the asymptotic giant branch (AGB) phase, characterised by strong mass loss through dust driven wi…
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…
Infrared Absorption and its Sources of CdZnTe at Cryogenic Temperature
Hiroshi Maeshima, Kosei Matsumoto, Yasuhiro Hirahara +10
To reveal the infrared absorption causes in the wavelength region between electronic and lattice absorptions, we measured the temperature dependence of the absorption coefficient o…
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…
