The UV Sensitivity of Axion Monodromy Inflation
Enrico Pajer, Dong-Gang Wang, Bowei Zhang
We revisit axion monodromy inflation in the context of UV-inspired models and point out that its cosmological observables are sensitive to heavy fields with masses far above the Hu…

Primordial non-Gaussianity constraints on dissipative inflation
Santiago Agüà Salcedo, Thomas Colas, Petar Suman +3
Dissipative effects appear in many early-Universe scenarios, yet their universal observational signatures and systematic confrontation with data remain largely unexplored. We emplo…

Bootstrapping the Cosmological Collider with Resonant Features
Dong-Gang Wang, Bowei Zhang
Signatures of heavy particles during inflation are exponentially suppressed by the Boltzmann factor when the masses are far above the Hubble scale. In more realistic scenarios, how…
