PIXIE
(Primordial Inflation Explorer)
(satellite-concept to to survey CMB polarization)
PIXIE (for Primordial Inflation Explorer) is a 2011 proposal
for a NASA Explorers Program mission intended to
survey CMB polarization, using a nulling
polarimeter.
Of particular interest are B-mode polarization modes
that are expected to be the imprint of primordial gravitational waves
caused by inflation.
It covers a substantial frequency-range,
from microwave to far infrared (30 GHz to 6 THz), also allowing it to
carry out intensity mapping of redshifted
C+, N+, and CO lines.
