Spitzer Infrared Low-Resolution Spectroscopic Study of Buried AGNs in a Complete Sample of Nearby Ultraluminous Infrared Galaxies
Masatoshi Imanishi, Roberto Maiolino, Takao Nakagawa
We present the results of Spitzer IRS low-resolution infrared 5-35 micron spectroscopy of 17 nearby ULIRGs at z < 0.2, optically classified as non-Seyferts. The presence of optical…
Studies of Expolanets and Solar Systems with SPICA
Michihiro Takami, Motohide Tamura, Keigo Enya +13
The SPace Infrared telescope for Cosmology and Astrophysics (SPICA) is a proposed mid-to-far infrared (4-200 um) astronomy mission, scheduled for launch in 2017. A single, 3.5m ape…
Properties of active galactic star-forming regions probed by imaging spectroscopy with the Fourier transform spectrometer (FTS) onboard AKARI
Yoko Okada, Mitsunobu Kawada, Noriko Murakami +8
We investigate the structure of the interstellar medium (ISM) and identify the location of possible embedded excitation sources from far-infrared (FIR) line and mid-infrared contin…
Far-infrared all sky diffuse mapping with AKARI
Y. Doi, M. Etxaluze Azkonaga, Glenn J. White +7
We discuss the capability of AKARI in recovering diffuse far-infrared emission, and examine the achieved reliability. Critical issues in making images of diffuse emission are the t…
Calibration and Performance of the AKARI Far-Infrared Surveyor (FIS) -- Slow-Scan Observation Mode for Point Sources
Mai Shirahata, Shuji Matsuura, Sunao Hasegawa +11
We present the characterization and calibration of the Slow-Scan observation mode of the Far-Infrared Surveyor (FIS) onboard the AKARI satellite. The FIS, one of the two focal-plan…
Hot debris dust around HD 106797
Hideaki Fujiwara, Takuya Yamashita, Daisuke Ishihara +10
Photometry of the A0 V main-sequence star HD 106797 with AKARI and Gemini/T-ReCS is used to detect excess emission over the expected stellar photospheric emission between 10 and 20…
