The future of cosmology? A case for CMB spectral distortions
Matteo Lucca
This thesis treats the topic of CMB Spectral Distortions (SDs), which represent any deviation from a pure black body shape of the CMB energy spectrum. As such, they can be used to…
CRRfast: An emulator for the Cosmological Recombination Radiation with effects from inhomogeneous recombination
Matteo Lucca, Jens Chluba, Aditya Rotti
The Cosmological Recombination Radiation (CRR) is one of the guaranteed CDM Spectral Distortion (SD) signals. Even if very small in amplitude, it provides a direct probe of the…
Quasi-extremal primordial black holes are a viable dark matter candidate
Jose A. de Freitas Pacheco, Elias Kiritsis, Matteo Lucca +1
Black hole evaporation is generally considered inevitable for low-mass black holes, yet there is no confirmation of this remarkable hypothesis. Here, we propose a phenomenological…
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…
Cosmological constraints on the decay of heavy relics into neutrinos
Thomas Hambye, Marco Hufnagel, Matteo Lucca
A massive particle decaying into neutrinos in the early Universe is known to be less constrained than if it was decaying into other standard model particles. However, even if the d…
Hints of dark matter-neutrino interactions in Lyman- data
Deanna C. Hooper, Matteo Lucca
In this work we investigate the possibility that dark matter and (massive) neutrinos can interact via a simple, constant cross section. Building on previous numerical efforts, we c…
Multi-interacting dark energy and its cosmological implications
Matteo Lucca
In the effort to define the main features a successful solution to the Hubble tension should have, growing evidence has emerged pointing to the need for models able to modify the e…
Dark energy-dark matter interactions as a solution to the tension
Matteo Lucca
In this work we consider a scenario where the dark energy is a dynamical fluid whose energy density can be transferred to the dark matter via a coupling function proportional to th…
Shedding light on the angular momentum evolution of binary neutron star merger remnants: a semi-analytic model
Matteo Lucca, Laura Sagunski, Federico Guercilena +1
The main features of the gravitational dynamics of binary neutron star systems are now well established. While the inspiral can be precisely described in the post-Newtonian approxi…
Constraining the inflationary potential with spectral distortions
Nils Schöneberg, Matteo Lucca, Deanna C. Hooper
Measuring spectral distortions (SDs) of the cosmic microwave background (CMB) will provide new constraints on previously unexplored scales of the primordial power spectrum, allowin…
The role of CMB spectral distortions in the Hubble tension: a proof of principle
Matteo Lucca
Although both early and late-time modifications of the CDM model have been proposed to address the Hubble tension, compelling arguments suggest that for a solution to be success…
Cosmology Intertwined IV: The Age of the Universe and its Curvature
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +88
A precise measurement of the curvature of the Universe is of primeval importance for cosmology since it could not only confirm the paradigm of primordial inflation but also help in…
Cosmology Intertwined III: and
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +89
The standard Cold Dark Matter cosmological model provides a wonderful fit to current cosmological data, but a few tensions and anomalies became statistically significant with t…
Cosmology Intertwined II: The Hubble Constant Tension
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +90
The current cosmological probes have provided a fantastic confirmation of the standard Cold Dark Matter cosmological model, that has been constrained with unprecedented accurac…
Cosmology Intertwined I: Perspectives for the Next Decade
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +89
The standard Cold Dark Matter cosmological model provides an amazing description of a wide range of astrophysical and astronomical data. However, there are a few big open quest…
Unlocking the synergy between CMB spectral distortions and anisotropies
Hao Fu, Matteo Lucca, Silvia Galli +4
Measurements of the cosmic microwave background (CMB) spectral distortions (SDs) will open a new window on the very early universe, providing new information complementary to that…
Dark matter as a heavy thermal hot relic
Thomas Hambye, Matteo Lucca, Laurent Vanderheyden
If, during the early Universe epoch, the dark matter particle thermalizes in a hidden sector which does not thermalize with the Standard Model thermal bath, its relativistic therma…
Tensions in the dark: shedding light on Dark Matter-Dark Energy interactions
Matteo Lucca, Deanna C. Hooper
The emergence of an increasingly strong tension between the Hubble rate inferred from early- and late-time observations has reinvigorated interest in nonstandard scenarios, with th…
The synergy between CMB spectral distortions and anisotropies
Matteo Lucca, Nils Schöneberg, Deanna C. Hooper +2
Spectral distortions and anisotropies of the CMB provide independent and complementary probes to study energy injection processes in the early universe. Here we discuss the synergy…
The lifetime of binary neutron star merger remnants
Matteo Lucca, Laura Sagunski
Although the main features of the evolution of binary neutron star systems are now well established, many details are still subject to debate, especially regarding the post-merger…
