Initial clustering of primordial black holes: A general formulation for arbitrary local non-Gaussianity
Hirotaka Ishijima, Teruaki Suyama, Ashu Kushwaha
Initial spatial clustering of primordial black holes (PBHs) induced by local-type non-Gaussianity (LNG) can substantially modify cosmological constraints on PBH abundance. Several…
A universal connection between lens density profiles and low-frequency wave optics in gravitational-wave lensing
So Tanaka, Teruaki Suyama
We investigate the low-frequency behavior of the amplification factor in gravitational lensing and explore how it encodes information about the density profile of the lensing objec…
Graviton Floor
Himeka Matsuo, Asuka Ito, Kazunori Kohri +2
It has been observed that the Universe is permeated by the cosmic photon background, ranging from radio waves to gamma rays. We investigate the conversion of the photon background…
Quantum description of gravitational waves generated by a classical source
Felix Laga, Teruaki Suyama
We investigate the quantum properties of gravitational waves (GWs) generated by a classical energy-momentum tensor. Treating the GW field as a quantum field coupled to a classical…
Consistency relations of amplitude and phase fluctuations of gravitational waves magnified by strong gravitational lensing
Yuta Nakazono, Teruaki Suyama
We discuss the amplitude and phase fluctuations of gravitational waves due to wave optics lensing in the presence of both a strong lens and cosmological weak lenses. By applying th…
Revisiting Constraints on Primordial Curvature Power Spectrum from PBH Abundances
Ashu Kushwaha, Teruaki Suyama
Primordial black holes (PBHs) can form in the early Universe, for instance during radiation domination, from the collapse of large-amplitude density perturbations shortly after hor…
