Searching for Cosmological Collider in the Planck CMB Data II: collider templates and Modal analysis
Petar Suman, Dong-Gang Wang, Wuhyun Sohn +2
Signatures of massive particles during inflation are highly informative targets for cosmological experiments. With recent progress on both theoretical and observational frontiers,…
How Significant are Cosmological Collider Signals in the Planck Data?
Petar Suman, Dong-Gang Wang, Wuhyun Sohn +2
The search for primordial non-Gaussianities (PNG) is theoretically well motivated but remains observationally challenging. Tight constraints with low significance for the standard…
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…
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…
