AKARI near-infrared spectroscopy of circumstellar hydrocarbon dust associated with young stellar objects
Yuki Kuroda, Hidehiro Kaneda, Natsuko Izumi +2
We investigate the processing of the circumstellar polycyclic aromatic hydrocarbons (PAHs) associated with young stellar objects (YSOs) through their stellar activities. We analyze…
A systematic study of CO/SiO absorption features in early-type galaxies using AKARI/IRC near-infrared spectra
Eiko Kozaki, Takuma Kokusho, Keiji Nakayama +5
The origin of dust in early-type galaxies (ETGs) remains a long-standing question, with proposed sources being mass loss from evolved stars, galaxy mergers, or grain growth in the…
A systematic study on the aromatic and aliphatic hydrocarbon emission features of nearby galaxies using AKARI near-IR spectra
Tsubasa Kondo, Hidehiro Kaneda, Shinki Oyabu +7
Interstellar hydrocarbon dust containing aromatic and aliphatic hydrocarbons, like polycyclic aromatic hydrocarbons (PAHs), is believed to be processed by various factors including…
Near-infrared [P II] and [Fe II] line mapping of Galactic supernova remnants
Takuma Kokusho, Yuki Katsurada, Yong-Hyun Lee +7
Phosphorus (P) is one of the key ingredients for life, yet its origins in galaxies remain poorly understood. In order to investigate the production of P by supernovae, we performed…
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…
Magnetic fields in the massive star-forming region NGC 6334 and their relationship with the properties of dust filaments probed by [CII] and PAH emissions
Takayoshi Kusune, Hayata Tsuji, Shinki Oyabu +7
We carried out the near-infrared () imaging polarimetric observation with the polarimeter SIRPOL on the Infrared Survey Facility (IRSF) 1.4 m telescope and [CII] line…
SILVIA: Ultra-precision formation flying demonstration for space-based interferometry
Takahiro Ito, Kiwamu Izumi, Isao Kawano +26
We propose SILVIA (Space Interferometer Laboratory Voyaging towards Innovative Applications), a mission concept designed to demonstrate ultra-precision formation flying between thr…
[CII] emission properties of the massive star-forming region RCW36 in a filamentary molecular cloud
T. Suzuki, S. Oyabu, S. K. Ghosh +10
Aims: To investigate properties of [CII]158 m emission of RCW36 in a dense filamentary cloud. Methods: [CII] observations of RCW36 covering an area of ~30 arcmin30 arcmi…
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…
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…
Large-scale mapping of the massive star-forming region RCW38 in the [CII] and PAH emission
H. Kaneda, T. Nakagawa, S. K. Ghosh +10
We investigate the large-scale structure of the interstellar medium (ISM) around the massive star cluster RCW38 in the [CII] 158 um line and polycyclic aromatic hydrocarbon (PAH) e…
AKARI Far-Infrared All Sky Survey
Y. Doi, M. Etxaluze Azkonaga, G. White +13
We demonstrate the capability of AKARI for mapping diffuse far-infrared emission and achieved reliability of all-sky diffuse map. We have conducted an all-sky survey for more than…
