Post-Newtonian expansion of scale-dependent gravity
Nicolas R. Bertini, Marcos H. Novaes
Scale-dependent gravity is an extension of general relativity in which the Newton and cosmological constants may vary slightly with the energy scale due to remnant low-energy quant…

Renormalization group corrections to CDM model and observational consequences for tension
Nicolas R. Bertini, Marcos H. Novaes, Rodrigo von Marttens +1
We explore the renormalization group-based extension of the CDM model as a potential solution to the current cosmological tensions. In this approach, both the cosmological cons…
