Search for AGNs in Near-Infrared
ῌMethod and Search Using the Methodῌ
Shinjirou KOUZUMA
School of International Liberal Studies, Chukyo
University, Toyota 470ῌ0393, Japan
Abstract : We have proposed near-infrared color
selection criteria to extract Active Galactic
Nuclei (AGNs). By examining the validity of
our color selection, it was found that most of
AGNs can be di#erentiated from stars and
several types of objects using the color selection.
In addition, we extracted new AGN candidates
using the color selection. Statistical properties of
the extracted candidates are consistent with
properties of known AGNs. Accordingly, most
of the candidates are expected to be real AGNs.
It should be noted that astronomical catalogues
have played a crucial role in this study.
