Observable Gravitational Wave Strain at Second Order
Guillem Domènech, Shi Pi, Ao Wang
There is currently no rigorous definition of gravitational wave strain at second order in cosmological perturbation theory. The usual association of gravitational waves with transv…
formalism: A new formulation for the probability density of the curvature perturbation
Diego Cruces, Shi Pi, Misao Sasaki
formalism is a useful method to calculate the curvature perturbation. Contrary to what it is typically done in the literature, we re-formulate the formalism by using the…
Fundamental Physics and Cosmology with TianQin
Jun Luo, Haipeng An, Ligong Bian +33
The exploration of the surrounding world and the universe is an important theme in the legacy of humankind. The detection of gravitational waves is adding a new dimension to this g…
Primordial Black Hole Formation from Power Spectrum with Finite-width
Shi Pi, Misao Sasaki, Volodymyr Takhistov +1
Primordial black holes (PBHs) can form from gravitational collapse of large overdensities in the early Universe, giving rise to rich phenomena in astrophysics and cosmology. We dev…
