The hand-made tail: Non-perturbative tails from multifield inflation
Ana Achucarro, Sebastian Cespedes, Anne-Christine Davis +1
It is becoming increasingly clear that large but rare fluctuations of the primordial curvature field, controlled by the tail of its probability distribution, could have dramatic ef…
Primordial gravitational waves from excited states
Jacopo Fumagalli, Gonzalo A. Palma, Sébastien Renaux-Petel +3
We show that a scalar excited state with large occupation numbers during inflation leads to an enhancement of tensor modes and a characteristic pattern of order-one oscillations in…
Four-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: On-sky Receiver Performance at 40, 90, 150, and 220 GHz Frequency Bands
Sumit Dahal, John W. Appel, Rahul Datta +37
The Cosmology Large Angular Scale Surveyor (CLASS) observes the polarized cosmic microwave background (CMB) over the angular scales of 1 90 with the…
