Elena Pierpaoli and her collaborator Slavash Yasini come up with a clever way of measuring the intrinsic CMB dipole, and disentangling it from the much bigger dipole induced by the Earth motion with respect to the CMB rest frame. The key idea is that leakage of the intrinsic dipole into the monopole and quadrupole induces […]
