A systematic study on the properties of aromatic and aliphatic hydrocarbon dust in active galactic nuclei with AKARI near-infrared spectroscopy
Risako Katayama, Hidehiro Kaneda, Takuma Kokusho +4
Recent near- and mid-infrared (IR) observations reveal the existence of appreciable amounts of aromatic and aliphatic hydrocarbon dust in the harsh environments of active galactic…
Spitzer/IRS full spectral modeling to characterize mineralogical properties of silicate dust in heavily obscured AGNs
T. Tsuchikawa, H. Kaneda, S. Oyabu +3
Mid-Infrared (IR) silicate dust bands observed in heavily obscured active galactic nuclei (AGNs) include information on the mineralogical properties of silicate dust. We aim to inv…
A systematic study of silicate absorption features in heavily obscured AGNs observed by Spitzer/IRS
T. Tsuchikawa, H. Kaneda, S. Oyabu +4
Heavily obscured active galactic nuclei (AGNs) are known to show deep silicate absorption features in the mid-infrared (IR) wavelength range of 10--20~m. The detailed profiles o…
Hydrogen recombination near-infrared line mapping of Centaurus A with IRSF/SIRIUS
R. Katayama, H. Kaneda, T. Kokusho +5
Centaurus A (Cen A) is one of the most famous galaxies hosting an active galactic nucleus (AGN), where the interaction between AGN activities and surrounding interstellar and inter…
Pixel-based spectral characterization of mid-infrared Si array detectors for astronomical observations in space
Takuro Tsuchikawa, Hidehiro Kaneda, Daisuke Ishihara +2
Mid-infrared (IR) array detectors have been used for astronomical observations in space. However, the uniformities of their spectral response curves have not been investigated in d…
A systematic study of Galactic infrared bubbles along the Galactic plane with AKARI and Herschel. II. Spatial distributions of dust components around the bubbles
Misaki Hanaoka, Hidehiro Kaneda, Toyoaki Suzuki +7
Galactic infrared (IR) bubbles, which can be seen as shell-like structures at mid-IR wavelengths, are known to possess massive stars within their shell boundaries. In our previous…
Near- to mid-infrared spectroscopy of the heavily obscured AGN LEDA 1712304 with AKARI/IRC
T. Tsuchikawa, H. Kaneda, S. Oyabu +5
Context. Although heavily obscured active galactic nuclei (AGNs) have been found by many observational studies, the properties of the surrounding dust are poorly understood. Using…
Dust properties in the cold and hot gas phases of the ATLAS3D early-type galaxies as revealed by AKARI
T. Kokusho, H. Kaneda, M. Bureau +6
The properties of the dust in the cold and hot gas phases of early-type galaxies (ETGs) are key to understand ETG evolution. We thus conducted a systematic study of the dust in a l…
A systematic study of Galactic infrared bubbles along the Galactic plane with AKARI and Herschel
Misaki Hanaoka, Hidehiro Kaneda, Toyoaki Suzuki +7
Galactic infrared (IR) bubbles, which have shell-like structures in the mid-IR wavelengths, are known to contain massive stars near their centers. IR bubbles in inner Galactic regi…
Enhanced dust emissivity power-law index along the western H filament of NGC 1569
Toyoaki Suzuki, Hidehiro Kaneda, Takashi Onaka +4
We used a data set from AKARI and Herschel images at wavelengths from 7 m to 500 m to catch the evidence of dust processing in galactic winds in NGC 1569. Images show a diffu…
