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…
Comparing multi-field primordial feature models with the Planck data
Matteo Braglia, Xingang Chen, Dhiraj Kumar Hazra
In this paper, we use a complete model of classical primordial standard clocks as an example to develop a methodology of directly comparing numerical predictions from complicated m…
Probing Primordial Features with the Stochastic Gravitational Wave Background
Matteo Braglia, Xingang Chen, Dhiraj Kumar Hazra
The stochastic gravitational wave background (SGWB) offers a new opportunity to observe signals of primordial features from inflationary models. We study their detectability with f…
Early modified gravity in light of the tension and LSS data
Matteo Braglia, Mario Ballardini, Fabio Finelli +1
We present a model of Early Modified Gravity (EMG) consisting in a scalar field with a non-minimal coupling to the Ricci curvature of the type plus a cosmol…
Unified framework for Early Dark Energy from -attractors
Matteo Braglia, William T. Emond, Fabio Finelli +2
One of the most appealing approaches to ease the Hubble tension is the inclusion of an early dark energy (EDE) component that adds energy to the Universe in a narrow redshift windo…
Generating PBHs and small-scale GWs in two-field models of inflation
Matteo Braglia, Dhiraj Kumar Hazra, Fabio Finelli +3
Primordial black holes (PBHs) generated by gravitational collapse of large primordial overdensities can be a fraction of the observed dark matter. In this paper, we introduce a mec…
