Mimicking Phantom Dark Energy with Evolving Dark Matter Mass
Lorenzo La Penna, Alessio Notari, Michele Redi
We present a general method to reproduce a given cosmological background through energy exchange between dark energy (DE) and dark matter (DM). This can be simply realized with a s…
BAO vs. SN evidence for evolving dark energy
Alessio Notari, Michele Redi, Andrea Tesi
We critically review the evidence for time-varying dark energy from recent Baryon Acoustic Oscillations (BAO) and Supernova (SN) observations. First, we show that such evidence is…
Reconstructing the Inflaton Potential: Primordial Black Holes and Gravitational Waves in Slow Roll and Ultra Slow Roll Single Field Inflation
Gabriele Autieri, Michele Redi
We present new single field inflationary scenarios that produce the critical abundance of primordial black holes as dark matter reconstructing the inflaton potential from an input…
Consistent Theories for the DESI dark energy fit
Alessio Notari, Michele Redi, Andrea Tesi
We search for physically consistent realizations of evolving dark energy suggested by the cosmological fit of DESI, Planck and Supernovae data. First we note that any lagrangian de…
