Abstract:
Local infrared (IR) luminosity functions (LFs) are necessary
benchmarks for high-redshift IR galaxy evolution studies. Any accurate
IR LF evolution studies require accordingly accurate local IR LFs. We
present IR galaxy LFs at redshifts of z≤0.3 from AKARI space
telescope, which performed an all-sky survey in six IR bands (9, 18,
65, 90, 140, and 160um) with 10 times better sensitivity than its
precursor Infrared Astronomical Satellite. Availability of 160um
filter is critically important in accurately measuring total IR
luminosity of galaxies, covering across the peak of the dust emission.
By combining data from Wide-field Infrared Survey Explorer (WISE),
Sloan Digital Sky Survey (SDSS) Data Release 13 (DR 13), six-degree
Field Galaxy Survey and the 2MASS Redshift Survey, we created a sample
of 15638 local IR galaxies with spectroscopic redshifts, factor of
7 larger compared to previously studied AKARI-SDSS sample. After
carefully correcting for volume effects in both IR and optical, the
obtained IR LFs agree well with previous studies, but comes with much
smaller errors. Measured local IR luminosity density is
{OMEGA}IR=1.19±0.05x108L☉/Mpc3. The contributions from
luminous IR galaxies and ultraluminous IR galaxies to {OMEGA}IR are
very small, 9.3 per cent and 0.9 per cent, respectively. There exists
no future all-sky survey in far-IR wavelengths in the foreseeable
future. The IR LFs obtained in this work will therefore remain an
important benchmark for high-redshift studies for decades.
Description:
In our aim to derive the most accurate local IR LF, we have
cross-matched the AKARI all-sky survey with the SDSS, 6dFGS, and 2MRS
to find 15638 IR galaxies with spectroscopic redshifts. We have
measured LIR by SED fitting based on the six AKARI, the four WISE IR
photometry bands. Especially, the far-IR photometry that cover the
peak of the dust emission SED allow us to have accurate LIR
measurements compared to the ones based on a bolometric conversion
factor.
