The polarized
microwave background:
ACTPol and
beyond
Jo Dunkley (Princeton Astrophysics)
Measurements of the Cosmic
Microwave Background
radiation have taught us a great deal about the origins and
content of the
universe, but there is still information to be extracted,
teaching us about the
energetic moments in
the early
universe, about neutrino physics and the later-time expansion
of the Universe. I
will show new results from
the
Atacama Cosmology Telescope Polarimeter
in
northern Chile, an experiment measuring the polarization of
the CMB. I will
then talk about the future: plans for new measurements from
the ground from the
Simons Observatory and the
CMB-S4 experiment,
and from space with the PIXIE satellite.
