Relaxing CMB bounds on Primordial Black Holes: the role of ionization fronts
Gaétan Facchinetti, Matteo Lucca, Sébastien Clesse
The accretion of matter onto primordial black holes (PBHs) during the dark ages and the subsequent energy injection in the medium should have left imprints on the cosmic microwave…
The effect of outflows on CMB bounds from Primordial Black Hole accretion
Lorenzo Piga, Matteo Lucca, Nicola Bellomo +4
Should Primordial Black Holes (PBHs) exist in nature, they would inevitably accrete baryonic matter in their vicinity. In turn, the consequent emission of high-energy radiation cou…
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…
Hints of Early Dark Energy in Planck, SPT, and ACT data: new physics or systematics?
Tristan L. Smith, Matteo Lucca, Vivian Poulin +5
We investigate constraints on early dark energy (EDE) using ACT DR4, SPT-3G 2018, Planck polarization, and restricted Planck temperature data (at ), finding a pref…
