Scalar-induced gravitational wave interpretation of PTA data: the role of scalar fluctuation propagation speed
Shyam Balaji, Guillem Domènech, Gabriele Franciolini
Pulsar timing arrays gathered evidence of the presence of a gravitational wave background around nHz frequencies. If the gravitational wave background was induced by large and Gaus…
Lectures on Gravitational Wave Signatures of Primordial Black Holes
Guillem Domènech
We provide a pedagogical approach to gravitational waves in cosmology with focus on gravitational wave signals related to primordial black holes. These lectures notes contain more…
Disformal symmetry in the Universe: mimetic gravity and beyond
Guillem Domènech, Alexander Ganz
Symmetries play an important role in fundamental physics. In gravity and field theories, particular attention has been paid to Weyl (or conformal) symmetry. However, once the theor…
Gravitational wave hints black hole remnants as dark matter
Guillem Domènech, Misao Sasaki
The end state of Hawking evaporation of a black hole is uncertain. Some candidate quantum gravity theories, such as loop quantum gravity and asymptotic safe gravity, hint towards P…
New universal property of cosmological gravitational wave anisotropies
Ameek Malhotra, Ema Dimastrogiovanni, Guillem Domènech +2
The anisotropies of the stochastic gravitational wave background, as produced in the early phases of cosmological evolution, can act as a key probe of the primordial universe parti…
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…
