Query: Dark-energy constraints with ALMA polarization measurements   The Cosmic Microwave Background (CMB) physics can be used to constrain the
dark energy dynamics: B modes of the polarization of the diffuse CMB emission
as well as the polarized signal towards clusters of galaxies are sensitive to
the Hubble expansion rate and thus the dark energy abundance in the early stage
of cosmic acceleration. The first effect is sourced by gravitational lensing of
large scale cosmic structures, the second is due to scattering of the primary
CMB temperature anisotropy quadrupole by free electrons in cluster plasma. We
are investigating the capabilities of ALMA to detect these effects and
constrain the high-redshift dark energy abundance through measurements of
sub-arcminute CMB anisotropies.
