Development of a new wideband heterodyne receiver system for the Osaka 1.85-m mm-submm telescope -- Receiver development & the first light of simultaneous observation in 230GHz and 345GHz bands with an SIS-mixer with 4-21GHz IF output
Sho Masui, Yasumasa Yamasaki, Hideo Ogawa +22
We have developed a wideband receiver system for simultaneous observations in CO lines of J = 2-1 and J = 3-2 transitions using the Osaka 1.85-m mm-submm telescope. As a frequency…
Return to Venus of the Japanese Venus Climate Orbiter AKATSUKI
Masato Nakamura, Yasuhiro Kawakatsu, Chikako Hirose +19
Japanese Venus Climate Orbiter/AKATSUKI was proposed in 2001 with strong support by international Venus science community and approved as an ISAS (The Institute of Space and Astron…
Near-infrared and Mid-infrared Spectroscopy with the Infrared Camera (IRC) for AKARI
Youichi Ohyama, Takashi Onaka, Hideo Matsuhara +22
The Infrared Camera (IRC) is one of the two instruments on board the AKARI satellite. In addition to deep imaging from 1.8-26.5um for the pointed observation mode of the AKARI, it…
Optical Identification of 15 Micron Sources in the AKARI Performance Verification Field toward the North Ecliptic Pole
Hideo Matsuhara, Takehiko Wada, Chris P. Pearson +28
We present the results of optical identifications for 257 mid-infrared sources detected with a deep 15um survey over approximately 80 arcmin^2 area in the AKARI performance verific…
The Infrared Camera (IRC) deep survey in the performance verification phase
Takehiko Wada, Shinki Oyabu, Yoshifusa Ita +17
We report the first results of a near- and mid- infrared deep survey with the Infrared Camera (IRC) onboard AKARI in the performance verification phase. Simultaneous observations b…
AKARI infrared imaging of reflection nebulae IC4954 and IC4955
Daisuke Ishihara, Takashi Onaka, Hidehiro Kaneda +26
We present the observations of the reflection nebulae IC4954 and IC4955 region with the Infrared Camera (IRC) and the Far-Infrared Surveyor (FIS) on board the infrared astronomical…
The Infrared Astronomical Mission AKARI
H. Murakami, H. Baba, P. Barthel +90
AKARI, the first Japanese satellite dedicated to infrared astronomy, was launched on 2006 February 21, and started observations in May of the same year. AKARI has a 68.5 cm cooled…
Detection of an H-alpha Emission Line on a Quasar, RX J1759.4+6638, at z=4.3 with AKARI
Shinki Oyabu, Takehiko Wada, Youichi Ohyama +18
We report the detection of an H-alpha emission line in the low resolution spectrum of a quasar, RX J1759.4+6638, at a redshift of 4.3 with the InfraRed Camera (IRC) onboard the AKA…
AKARI observations of circumstellar dust in the globular clusters NGC104 and NGC362
Yoshifusa Ita, Toshihiko Tanabe, Noriyuki Matsunaga +19
We report preliminary results of AKARI observations of two globular clusters, NGC104 and NGC362. Imaging data covering areas of about 10x10 arcmin^2 centered on the two clusters ha…
The Infrared Camera (IRC) for AKARI - Design and Imaging Performance
T. Onaka, H. Matsuhara, T. Wada +25
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 m…
Multi-wavelength analysis of 18um-selected galaxies in the AKARI/IRC monitor field towards the North Ecliptic Pole
T. Takagi, H. Matsuhara, T. Wada +25
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 capabilit…
Nature of Infrared Sources in 11 micron Selected Sample from Early Data of the AKARI North Ecliptic Pole Deep Survey
