Approximate gauge independence of the induced gravitational wave spectrum
Guillem Domènech, Misao Sasaki
Gravitational waves (GWs) induced by scalar curvature fluctuations are an important source of the cosmological GW background and a crucial counterpart of the primordial black hole…
Gravitational wave constraints on the primordial black hole dominated early universe
Guillem Domènech, Chunshan Lin, Misao Sasaki
We calculate the gravitational waves (GWs) induced by the density fluctuations due to inhomogeneous distribution of primordial black holes (PBHs) in the case where PBHs eventually…
NANOGrav Hints on Planet-Mass Primordial Black Holes
Guillem Domènech, Shi Pi
Recently, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) claimed the detection of a stochastic common-spectrum process of the pulsar timing array (PTA)…
Neutrino masses, vacuum stability and quantum gravity prediction for the mass of the top quark
Guillem Domènech, Mark Goodsell, Christof Wetterich
A general prediction from asymptotically safe quantum gravity is the approximate vanishing of all quartic scalar couplings at the UV fixed point beyond the Planck scale. A vanishin…
Induced gravitational waves as a probe of thermal history of the universe
Guillem Domènech, Shi Pi, Misao Sasaki
The scalar perturbation induced gravitational waves are a probe of the primordial density perturbation spectrum on small scales. In this paper, we show that they can also probe the…
Planck residuals anomaly as a fingerprint of alternative scenarios to inflation
Guillem Domènech, Xingang Chen, Marc Kamionkowski +1
Planck's residuals of the CMB temperature power spectrum present a curious oscillatory shape that resembles an extra smoothing effect of lensing and is the source of the lensing an…
