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…

Matter bounce cosmology with a generalized single field: non-Gaussianity and an extended no-go theorem
Yu-Bin Li, Jerome Quintin, Dong-Gang Wang +1
We extend the matter bounce scenario to a more general theory in which the background dynamics and cosmological perturbations are generated by a -essence scalar field with an ar…

Bouncing cosmologies with dark matter and dark energy
Yi-Fu Cai, Antonino Marciano, Dong-Gang Wang +1
We review matter bounce scenarios where the matter content is dark matter and dark energy. These cosmologies predict a nearly scale-invariant power spectrum with a slightly red til…
