The synergy between CMB spectral distortions and anisotropies
Matteo Lucca, Nils Schöneberg, Deanna C. Hooper +2
Spectral distortions and anisotropies of the CMB provide independent and complementary probes to study energy injection processes in the early universe. Here we discuss the synergy…
The BAO+BBN take on the Hubble tension
Nils Schöneberg, Julien Lesgourgues, Deanna C. Hooper
Many attempts to solve the Hubble tension with extended cosmological models combine an enhanced relic radiation density, acting at the level of background cosmology, with new physi…
Constraining Dark Matter -- Dark Radiation interactions with CMB, BAO, and Lyman-
Maria Archidiacono, Deanna C. Hooper, Riccardo Murgia +3
Several interesting Dark Matter (DM) models invoke a dark sector leading to two types of relic particles, possibly interacting with each other: non-relativistic DM, and relativisti…
