Constraining the inflationary potential with spectral distortions
Nils Schöneberg, Matteo Lucca, Deanna C. Hooper
Measuring spectral distortions (SDs) of the cosmic microwave background (CMB) will provide new constraints on previously unexplored scales of the primordial power spectrum, allowin…
Cosmological constraints on multi-interacting dark matter
Niklas Becker, Deanna C. Hooper, Felix Kahlhoefer +2
The increasingly significant tensions within CDM, combined with the lack of detection of dark matter (DM) in laboratory experiments, have boosted interest in non-minimal dark se…
Cannibalism hinders growth: Cannibal Dark Matter and the tension
Stefan Heimersheim, Nils Schöneberg, Deanna C. Hooper +1
Many models of dark matter have been proposed in attempt to ease the tension between weak lensing and CMB experiments. One such exciting possibility is cannibalistic dark mat…
Unlocking the synergy between CMB spectral distortions and anisotropies
Hao Fu, Matteo Lucca, Silvia Galli +4
Measurements of the cosmic microwave background (CMB) spectral distortions (SDs) will open a new window on the very early universe, providing new information complementary to that…
Non-Cold Dark Matter from Primordial Black Hole Evaporation
Iason Baldes, Quentin Decant, Deanna C. Hooper +1
Dark matter coupled solely gravitationally can be produced through the decay of primordial black holes in the early universe. If the dark matter is lighter than the initial black h…
Tensions in the dark: shedding light on Dark Matter-Dark Energy interactions
Matteo Lucca, Deanna C. Hooper
The emergence of an increasingly strong tension between the Hubble rate inferred from early- and late-time observations has reinvigorated interest in nonstandard scenarios, with th…
