Effect of stochastic kicks on primordial black hole abundance and mass via the compaction function
Sami Raatikainen, Syksy Rasanen, Eemeli Tomberg
We study stochastic effects in viable ultra-slow-roll inflation models that produce primordial black holes. We consider asteroid, solar, and supermassive black hole seed masses. In…

Primordial black hole compaction function from stochastic fluctuations in ultra-slow-roll inflation
Sami Raatikainen, Syksy Rasanen, Eemeli Tomberg
We study the formation of primordial black holes (PBH) with ultra-slow-roll inflation when stochastic effects are important. We use the formalism and simplify the stochastic e…

Higgs inflation and teleparallel gravity
Sami Raatikainen, Syksy Rasanen
Teleparallel gravity is a formulation of general relativity that is physically equivalent to metric gravity if the gravitational action has the Einstein-Hilbert form and matter is…
