The rise of the primordial tensor spectrum from an early scalar-tensor epoch
Debika Chowdhury, Gianmassimo Tasinato, Ivonne Zavala
Primordial gravitational waves (PGW) produced during inflation span a large range of frequencies, carrying information on the dynamics of the primordial universe. During an early s…
A new mechanism to enhance primordial tensor fluctuations in single field inflation
Maria Mylova, Ogan Özsoy, Susha Parameswaran +2
We discuss a new mechanism to enhance the spectrum of primordial tensor fluctuations in single field inflationary scenarios. The enhancement relies on a transitory non-attractor in…
An exact solution for a rotating black hole in modified gravity
Francesco Filippini, Gianmassimo Tasinato
Exact solutions describing rotating black holes can offer important tests for alternative theories of gravity, motivated by the dark energy and dark matter problems. We present an…
Exploring Cosmic Origins with CORE: Inflation
CORE Collaboration, Fabio Finelli, Martin Bucher +129
We forecast the scientific capabilities to improve our understanding of cosmic inflation of CORE, a proposed CMB space satellite submitted in response to the ESA fifth call for a m…
Galaxy bispectrum, primordial non-Gaussianity and redshift space distortions
Matteo Tellarini, Ashley J. Ross, Gianmassimo Tasinato +1
Measurements of the non-Gaussianity of the primordial density field have the power to considerably improve our understanding of the physics of inflation. Indeed, if we can increase…
Cosmology of bigravity with doubly coupled matter
Denis Comelli, Marco Crisostomi, Kazuya Koyama +2
We study cosmology in the bigravity formulation of the dRGT model where matter couples to both metrics. At linear order in perturbation theory two mass scales emerge: an hard one f…
