Inflation in light of ACT/SPT: A new perspective from Weyl gravity
Qing-Yang Wang
Recent measurements from the Atacama Cosmology Telescope (ACT) and the South Pole Telescope (SPT) have placed the strictest constraints on the primordial scalar perturbation spectr…
Purely gravitational dark matter production in warm inflation
Qing-Yang Wang, Tianyu Jia, Pei-Ran Chen +1
We consider an appealing scenario for the production of purely gravitational dark matter in the background of warm inflation, a mechanism that maintains stable thermal bath during…
Gravitational Waves from Preheating in Inflation with Weyl Symmetry
Wei-Yu Hu, Qing-Yang Wang, Yan-Qing Ma +1
Inflation with Weyl scaling symmetry provides a viable scenario that can generate both the nearly scaling invariant primordial density fluctuation and a dark matter candidate. Here…
Inflation in Weyl Scaling Invariant Gravity with Extensions
Qing-Yang Wang, Yong Tang, Yue-Liang Wu
The cosmological observations of cosmic microwave background and large-scale structure indicate that our universe has a nearly scaling invariant power spectrum of the primordial pe…
Dark Matter Production in Weyl Inflation
Qing-Yang Wang, Yong Tang, Yue-Liang Wu
Dark matter and inflation are two key elements to understand the origin of cosmic structures in modern cosmology, and yet their exact physical models remain largely uncertain. The…
