The Tiered Radio Extragalactic Continuum Simulation (T-RECS)
  We present the Tiered Radio Extragalactic Continuum Simulation (T-RECS): a
new simulation of the radio sky in continuum, over the 150 MHz-20 GHz range.
T-RECS models two main populations of radio galaxies: Active Galactic Nuclei
(AGNs) and Star-Forming Galaxies (SFGs), and corresponding sub-populations. Our
model also includes polarized emission over the full frequency range, which has
been characterised statistically for each population using the available
information. We model the clustering properties in terms of probability
distributions of hosting halo masses, and use lightcones extracted from a
high-resolution cosmological simulation to determine the positions of haloes.
This limits the sky area for the simulations including clustering to a 25deg2
field of view. We compare luminosity functions, number counts in total
intensity and polarization, and clustering properties of our outputs to
up-to-date compilations of data and find a very good agreement. We deliver a
set of simulated catalogues, as well as the code to produce them, which can be
used for simulating observations and predicting results from deep radio surveys
with existing and forthcoming radio facilities, such as the Square Kilometre
Array (SKA).
