Abstract: The radio sky covers a large range of
sources, from small single galaxies to large clusters of galaxies and
the space between them. These sources consist of some of the most
powerful objects in the Universe, as well as diffuse weak emitters;
all together these sources make up the Cosmic Radio Background
(CRB). Understanding the radio background can tell us about how
galaxies have evolved over time, the different kinds of galaxy
populations, the star formation history of the Universe, and the role
of magnetism, as well as details of large-scale structure and
clustering. Advancements in radio telescopes and novel data analysis
techniques now allow us to push observational limits to new depths,
probing fainter galaxies and farther back in cosmic time.This talk
will discuss the use of some of these new data and statistical
techniques (such as confusion analysis and cross correlations) for
studying point sources and source counts as well as diffuse cluster
emission and the synchrotron cosmic web. I will go over the benefits
and challenges to statistical techniques for investigating the nature
of the faint extragalactic components of the radio sky.
