  To understand the feedback of black holes on their environment or the
acceleration of ultra-high energy cosmic rays in the present cosmic epoch, a
systematic, all-sky inventory of radio galaxies in the local universe is
needed. Here we present the first catalog of radio-emitting galaxies that meets
this requirement. Our catalog allows the selection of volume-limited subsamples
containing all low-power radio galaxies, similar to the prototypical low-power
radio galaxies Cen A or M87, within some hundred Mpc. It is constructed by
matching radio emission from the NVSS and SUMSS surveys to galaxies of the
2MASS Redshift Survey (2MRS) using an image-level algorithm that properly
treats the extended structure of radio sources. The sample contains 575
radio-emitting galaxies with a flux greater than 213 mJy at 1.4 GHz. Over 30%
of the galaxies in our catalog are not contained in existing large-area
extra-galactic radio samples. We compute the optical and radio luminosity
functions and the fraction of radio galaxies as a function of galaxy
luminosity. We find that the galaxy density around radio galaxies is
significantly higher than around non-radio galaxies of the same luminosity and
morphology. This enhanced clustering suggests a causal relation between
external galaxy properties, such as environment or merger history, and the
formation of powerful jets in the present universe. Since the enhancement is
observed with respect to galaxies of the same luminosity and Hubble type, it is
not primarily driven by black hole mass. Our automated matching procedure is
found to select radio-emitting galaxies with high efficiency (99%) and purity
(91%), which is key for future processing of deeper, larger samples.
