Recent simulations predict that the presence of stellar bulge suppress the
efficiency of star formation in early-type galaxies, and this `morphological
quenching' scenario is supported by many observations. In this study, we
discuss the net effect...
The aim of this work is to create a new catalog of reliable AGN candidates
selected from the AKARI NEP-Deep field. Selection of the AGN candidates was
done by applying a fuzzy SVM algorithm, which allows to incorporate measurement
uncertainties in...

Evolutionary properties of infrared (IR) luminous galaxies are important keys
to understand dust-obscured star formation history and galaxy evolution. Based
on the near- to mid-IR imaging with 9 continuous filters of AKARI space
telescope, we pres...

Much of the star formation is obscured by dust. For the complete
understanding of the cosmic star formation history (CSFH), infrared (IR) census
is indispensable. AKARI carried out deep mid-infrared observations using its
continuous 9-band filters...

Revealing what fraction of galaxies harbor AGN is central in understanding
black hole accretion history of the Universe. However, optical and soft X-ray
surveys miss the most highly obscured AGNs. Infrared (IR), instead, is more
robust against abs...
