Session:
Inflation and Primordial Blackholes
Heavy particles can be produced on shell during inflation and leave distinct signals in the correlations of density fluctuations. These so-called cosmological collider signals can be searched for in the future CMB/LSS/21cm observations. In this talk I will introduce the basics of the cosmological collider program. I will then talk about our current understanding of the signal structure and the und

Session:
Inflation and Primordial Blackholes
In this talk, I will talk about two topics on GWs induced by scalar perturbations.
One is about the enhancement of induced GWs with a sudden reheating, named the “Poltergeist mechanism”. When the universe experiences an early matter-dominated era that ends with a sudden reheating, the induced GWs are much enhanced due to fast oscillations of the scalar perturbations after the reheating. I wi

Session:
Inflation and Primordial Blackholes
In this talk, we discuss gravitation wave signals not from inflation itself, but from models that are built using inflationary ideas. In particular, a post-inflationary epoch of evolving scalar VEV(s) can generate the observed baryon asymmetry through the Affleck-Dine mechanism. As this involves high scale physics, it is difficult to test experimentally, but we argue that the poltergeist mechan

Session:
Inflation and Primordial Blackholes
We will introduce CosmoLattice, a modern code for simulating the non-linear dynamics of interactive fields in an expanding background. As an application we will solve two different problems of inflationary cosmology: i) the non-linear dynamics of axion-inflation, ii) the use of gravitational waves from preheating as a probe of particle interactions

Session:
Inflation and Primordial Blackholes
Gravitational waves (GWs) have the potential to probe the entirety of cosmological history due to their nearly perfect decoupling from the thermal bath and any intervening matter after emission. In this talk, we will review the basic physics of spectral distortions (SDs) of the cosmic microwave background (CMB), and highlight how they uniquely probe GWs over six decades in frequency, bridging the
