Quantum corrections to quartic inflation with a non-minimal coupling: metric vs. Palatini
Tommi Markkanen, Tommi Tenkanen, Ville Vaskonen +1
We study models of quartic inflation where the inflaton field is coupled non-minimally to gravity, , and perform a study of quantum corrections in curved space-time at…
Gravitational Waves from Primordial Black Hole Mergers
Martti Raidal, Ville Vaskonen, Hardi Veermäe
We study the production of primordial black hole (PBH) binaries and the resulting merger rate, accounting for an extended PBH mass function and the possibility of a clustered spati…
Single Field Double Inflation and Primordial Black Holes
Kristjan Kannike, Luca Marzola, Martti Raidal +1
Within the framework of scalar-tensor theories, we study the conditions that allow single field inflation dynamics on small cosmological scales to significantly differ from that of…
Primordial black hole constraints for extended mass functions
Bernard Carr, Martti Raidal, Tommi Tenkanen +2
We revisit the cosmological and astrophysical constraints on the fraction of the dark matter in primordial black holes (PBHs) with an extended mass function. We consider a variety…
