Benchmarking wall velocities in cosmological phase transitions: Fluid Ansatz and WallGo
Gláuber C. Dorsch, Marek Lewicki, Daniel A. Pinto
A reliable computation of the bubble wall velocity during a cosmological phase transition requires an adequate modeling of the non-equilibrium dynamics in the vicinity of this expa…
Reheating matters: Starobinsky inflation in light of joint CMB+BAO results and gravitational-wave forecasts
Gláuber C. Dorsch, Lucas P. C. Leão, Lucas M. B. Alves +2
It has been noted in the literature that, if post-inflationary reheating is dominated by a stiff fluid with equation of state (EoS) , then the predictions of Starobinsky in…
Reheating after Starobinsky Inflation in the Jordan Frame
Gláuber C. Dorsch, Luiz Carlos Miranda, Nelson Yokomizo
We investigate gravitational reheating in the Starobinsky model in the Jordan frame, where inflation is driven by an modification of gravity with no explicit inflaton field.…
Gravitational reheating in Starobinsky inflation
Gláuber C. Dorsch, Luiz Miranda, Nelson Yokomizo
We investigate the possibility of achieving post-inflationary reheating exclusively through the gravitational interaction in Starobinsky inflation, which itself assumes nothing but…
Brazilian Report on Dark Matter 2024
I. F. M. Albuquerque, J. Alcaniz, A. Alves +51
One of the key scientific objectives for the next decade is to uncover the nature of dark matter (DM). We should continue prioritizing targets such as weakly-interacting massive pa…
Cosmological phase transitions from the functional measure
Bruno Berganholi, Gláuber C. Dorsch, Iberê Kuntz +2
We investigate how competitive gravitational wave detectors can be to current and near-future colliders in probing a model where the new physics is completely encapsulated in a mod…
