Hybrid -attractors, primordial black holes and gravitational wave backgrounds
Matteo Braglia, Andrei Linde, Renata Kallosh +1
We investigate the two-stage inflation regime in the theory of hybrid cosmological -attractors. The spectrum of inflationary perturbations is compatible with the latest Planck/B…
Questions on calculation of primordial power spectrum with large spikes: the resonance model case
Keisuke Inomata, Matteo Braglia, Xingang Chen +1
Inflationary models predicting a scale-dependent large amplification of the density perturbations have recently attracted a lot of attention because the amplified perturbations can…
Back to the features: assessing the discriminating power of future CMB missions on inflationary models
Matteo Braglia, Xingang Chen, Dhiraj Kumar Hazra +1
Future Cosmic Microwave Background (CMB) experiments will deliver extremely accurate measurements of the E-modes pattern of the CMB polarization field. Given the sharpness of the E…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
Inflation: Theory and Observations
Ana Achúcarro, Matteo Biagetti, Matteo Braglia +19
Cosmic inflation provides a window to the highest energy densities accessible in nature, far beyond those achievable in any realistic terrestrial experiment. Theoretical insights i…
Tracking the origin of black holes with the stochastic gravitational wave background popcorn signal
Matteo Braglia, Juan Garcia-Bellido, Sachiko Kuroyanagi
Unresolved sources of gravitational waves (GWs) produced by the merger of a binary of black holes at cosmological distances combine into a stochastic background. Such a background…
