Exploring Non-minimal coupling using ultra-diffuse galaxies
Saboura Zamani, Vincenzo Salzano, Dario Bettoni
We investigate whether a non-minimal coupling between dark matter and gravity can influence the internal dynamics of ultra-diffuse galaxies. Within this framework, the gravitationa…
Hubble-Induced Phase Transitions: Gravitational-Wave Imprint of Ricci Reheating from Lattice Simulations
Dario Bettoni, Giorgio Laverda, Asier Lopez-Eiguren +1
Gravitational waves offer an unprecedented opportunity to look into the violent high-energy processes happening during the reheating phase of our Universe. We consider a Hubble-ind…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Evidence of doubly OZI-suppressed decay in the radiative decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +678
Using a sample of events collected with the BESIII detector at the BEPCII collider, the first evidence for the doubly OZI-suppressed decay $η_{…
Nonminimally coupled Dark Matter in Clusters of Galaxies: a fully comprehensive analysis
Saboura Zamani, Vincenzo Salzano, Dario Bettoni
In this study, we explore how a non-minimal coupling between dark matter and gravity can affect the behavior of dark matter in galaxy clusters. We have considered the case of a dis…
