Revisiting the Matter Creation Process: Observational Constraints on Gravitationally Induced Dark Energy and the Hubble Tension
Tiziano Schiavone, Mariaveronica De Angelis, Luis A. Escamilla +2
The Hubble tension and the unknown origin of dark energy motivate the exploration of alternative mechanisms for late-time cosmic acceleration. We investigate gravitationally induce…
Modified gravity in the presence of matter creation: scenario for the late Universe
Giovanni Montani, Nakia Carlevaro, Mariaveronica De Angelis
We consider a dynamic scenario for characterizing the late Universe evolution, aiming to mitigate the Hubble tension. Specifically, we consider a metric gravity in the Jorda…
Testing scale-invariant inflation against cosmological data
Chiara Cecchini, Mariaveronica De Angelis, William Giarè +2
There is solid theoretical and observational motivation behind the idea of scale-invariance as a fundamental symmetry of Nature. We consider a recently proposed classically scale-i…
Gravitational waves in a cyclic Universe: resilience through cycles and vacuum state
Mariaveronica De Angelis, Adam Smith, William Giarè +1
We present a generalised calculation for the spectrum of primordial tensor perturbations in a cyclic Universe, making no assumptions about the vacuum state of the theory and accoun…
