Planck Collaboration, P. A. R. Ade, N. Aghanim +202
The Andromeda Galaxy (M31) is one of a few galaxies that has sufficient angular size on the sky to be resolved by the Planck satellite. Planck has detected M31 in all of its freque…
Detection of non-classical space-time correlations with a novel type of single-photon camera
Felix Just, Mykhaylo Filipenko, Andrea Cavanna +9
