Galaxy colours in the AKARI deep SEP survey

Nakagawa, Takao; Shirahata, Mai; Jeong, Woong-Seob +7 more

We investigate the segregation of the extragalactic population via colour criteria to produce an efficient and inexpensive methodology to select specific source populations as a function of far-infrared flux. Combining galaxy evolution scenarios and a detailed spectral library of galaxies, we produce simulated catalogues incorporating segregation …

AKARI (ASTRO-F): Flight performance and preliminary results

Shibai, Hiroshi

ASTRO-F, which is the first Japanese satellite mission dedicated to the infrared wavelength region, was successfully launched on February 21, 2006 (UT), and was named "AKARI". The telescope has a 69 cm aperture, and is cooled to 6 K with super-fluid helium and mechanical coolers. AKARI is designed for the most advanced all-sky survey in the mid- a…

Detection of CFIRB with AKARI/FIS deep observations

Nakagawa, Takao; Shirahata, Mai; Jeong, Woong-Seob +8 more

The Cosmic Far-Infrared Background (CFIRB) contains information about the number and distribution of contributing sources and thus gives us an important key to understand the evolution of galaxies. Using a confusion study to set a fundamental limit to the observations, we investigate the potential to explore the CFIRB with AKARI/FIS deep observati…
