Tracing cosmic stretch marks: probing scale invariance in the early Universe
Mariaveronica De Angelis, Chiara Cecchini, Massimiliano Rinaldi
This paper investigates a scale-invariant inflationary model characterized by a scalar field non-minimally coupled to gravity and a curvature term quadratic in the Ricci scalar. Th…
Implications of cosmologically coupled black holes for pulsar timing arrays
Marco Calzà, Francesco Gianesello, Massimiliano Rinaldi +1
It has been argued that realistic models of (singularity-free) black holes (BHs) embedded within an expanding Universe are coupled to the large-scale cosmological dynamics, with st…
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…
