| Abstract: |
We have investigated on the nature of the radio source near the star
SAO206462. Although several recent efforts concluded that the galaxy
does not significantly pollute the prominent IR flux of the star, we
consider convenient to establish the properties of the galaxy and
explore a method that can be used when a stellar FIR image is polluted
by background extragalactic objects. Using archival data available from
2MASS, WISE and radio at 1.4 GHz, we conducted a comparison with the spectral energy
distributions of a set of galaxy templates of different morphologies.
Through a spectral energy distribution (SED) fitting method we have determined the
galaxy photometric redshift, zphot∼ 0.1, its IR luminosity, LIR∼ 4 x 1011L☉, and
the star formation rate, 53 M☉/yr. These properties, in addition to the possible
presence of an obscured AGN, are consistent with the typical
scenarios that characterize local luminous IR galaxies (LIRGs). |
