Abstract:
We identified 15658 NRAO VLA Sky Survey (NVSS) radio sources among the
55288 2 Micron All-Sky Survey eXtended (2MASX) galaxies brighter than
k20fe=12.25 at λ=2.16µm and covering the Ω=7.016sr
of sky defined by J2000 δ>-40° and |b|>20°. The complete
sample of 15043 galaxies with 1.4GHz flux densities S≥2.45mJy
contains a 99.9% spectroscopically complete subsample of 9517 galaxies
with k20fe≤11.75. We used only radio and infrared data to
quantitatively distinguish radio sources powered primarily by recent
star formation from those powered by active galactic nuclei. The radio
sources with log[L(W/Hz)]>19.3 that we used to derive the local
spectral luminosity and power-density functions account for >99% of
the total 1.4GHz spectral power densities
USF=(1.54±0.20)x1019W/Hz/Mpc3 and
UAGN=(4.23±0.78)x1019W/Hz/Mpc3 in the universe today, and the
spectroscopic subsample is large enough that the quoted errors are
dominated by cosmic variance. The recent comoving star formation rate
density indicated by USF is ψ∼0.015M☉/yr/Mpc3.
