Exploring Evaporating Primordial Black Holes with Gravitational Waves
Guillem Domènech, Volodymyr Takhistov, Misao Sasaki
Primordial black holes (PBHs) from the early Universe have been connected with the nature of dark matter and can significantly affect cosmological history. We show that coincidence…
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…
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…
Could the black hole singularity be a field singularity?
Guillem Domènech, Atsushi Naruko, Misao Sasaki +1
In the wake of interest to find black hole solutions with scalar hair, we investigate the effects of disformal transformations on static spherically symmetric space-times with a no…
Induced gravitational waves in a general cosmological background
Guillem Domènech
Gravitational waves are inevitably produced by second order terms in cosmological perturbation theory. Most notably, the so-called induced gravitational waves are a window to the s…
