Resolved 24.5 micron emission from massive young stellar objects
W. J. de Wit, M. G. Hoare, T. Fujiyoshi +8
Massive young stellar objects (MYSO) are surrounded by massive dusty envelopes. Our aim is to establish their density structure on scales of ~1000 AU, i.e. a factor 10 increase in…
A red supergiant nebula at 25 micron: arcsecond scale mass-loss asymmetries of mu Cep
W. J. de Wit, R. D. Oudmaijer, T. Fujiyoshi +8
We present diffraction limited (0.6") 24.5micron Subaru/COMICS images of the red supergiant mu Cep. We report the detection of a circumstellar nebula, that was not detected at shor…
Dark Matter Substructure in Lensing Galaxies
Masashi Chiba, Takeo Minezaki, Kaiki T. Inoue +3
To set useful limits on the abundance of small-scale dark matter halos (subhalos) in a galaxy scale, we have carried out mid-infrared imaging and integral-field spectroscopy for a…
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…
