An AKARI Search for Intracluster Dust of Globular Clusters (2008)
Matsunaga, N., Mito, H., Nakada, Y., Fukushi, H., Tanabé, T., Ita, Y., ...
We report the observations of 12 globular clusters with the AKARI/FIS. Our goal is to search for emission from the cold dust within clusters. We detect diffuse emissions toward NGC 6402 and 2808, but...

The Infrared Camera (IRC) for AKARI - Design and Imaging Performance (2007)
Onaka, T., Matsuhara, H., Wada, T., Fujishiro, N., Fujiwara, H., Ishigaki, M., ...
The Infrared Camera (IRC) is one of two focal-plane instruments on the AKARI satellite. It is designed for wide-field deep imaging and low-resolution spectroscopy in the near- to mid-infrared...
Takagi, T., Matsuhara, H., Wada, T., Oyabu, S., Imai, K., Pearson, C. P., ...
We present an initial analysis of AKARI 18um-selected galaxies using all 9 photometric bands at 2-24um available in the InfraRed Camera (IRC), in order to demonstrate new capabilities of AKARI...
An SiO Maser Search off the Galactic Plane (2007)
Deguchi, S., Fujii, T., Ita, Y., Imai, H., Izumiura, H., Kameya, O., ...
We have searched for the SiO J=1--0 v= 1 and 2 maser lines at ~ 43 GHz in 277 2MASS/MSX/IRAS sources off the Galactic plane (|b|> 3 deg), which resulted in 119 (112 new) detections. Among the new...
Observations of Stellar Maser Sources with no IRAS Counterpart (2005)
Deguchi, S., Nakashima, J., Miyata, T., Ita, Y.
We investigated stellar maser sources with no IRAS counterpart at the radio, middle-infrared, and near-infrared wavelengths. A 43 GHz SiO maser search for 120 2MASS/MSX objects, and 10 OH 1612 MHz...
Red Variables in Globular Clusters: Comparison with the Bulge and the LMC (2005)
Matsunaga, N., Nakada, Y., Tanabe, T., Fukushi, H., Ita, Y.
We are conducting a project aimed at surveys and repeated observations of red variables (or long-period variables) in globular clusters. Using the IRSF/SIRIUS near-infrared facility located at South...
