Variations in the 3.3 µm feature and carbonaceous dust in AKARI data
Hammonds, M.; Mori, T.; Usui, F. +1 more
A wealth of near infrared spectroscopic data for a large number of galactic objects was recorded with AKARI during its active lifetime. The hydrocarbon emission features around 3.3 - 3.5 m are modelled here as a series of 6 Voigt profiles arising due to hydrogen atoms found in different molecular structures within the emitting spectroscopic carrie…
A study of iron and dust in the supernova remnant IC 443
Onaka, Takashi; Lee, Ho-Gyu; Kaneda, Hidehiro +3 more
We performed near-infrared line mapping of the supernova remnant IC 443 with the IRSF 1.4-m telescope, using the narrow-band filters tuned for [Fe II] 1.257 µm, [Fe II] 1.644 µm, and Paβ. We detected the [Fe II] and Paβ emissions from a very wide area of the observed region (30‧ ×35‧). These line intensity maps re…
An AKARI infrared study of dust emission in Galactic bubbles indicative of large-scale cloud-cloud collisions
Kaneda, H.; Sano, H.; Ishihara, D. +3 more
We report our systematic study on dust emission in massive star-forming regions indicative of large-scale cloud-cloud collisions, using the AKARI infrared (IR) all-sky survey data at wavelengths of 9, 18, 65, 90, 140, and 160 µm. We focus on the Galactic bubbles catalogued by Spitzer, which are categorized into two types of morphology, close…
