Large scale structures: from inflation to today: a brief report
Lina Castiblanco, Radouane Gannouji, Clément Stahl
We briefly review some selected topics gravitating around large scale structures. We derive from inflation the evolution of dark matter perturbations. The stress is put on the non-…
Charged cosmological black hole
Rahim Moradi, Clément Stahl, Javad T. Firouzjaee +1
The cosmological black holes are black holes living not in an asymptotically flat universe but in an expanding spacetime. They have a rich dynamics in particular for their mass and…
On early and late phases of acceleration of the expansion of the universe
Clément Stahl
This thesis tackles the vast question of generating accelerated periods of expansion of the universe. Models loosely related were developed in the early and late universe. In the e…
Fermionic current and Schwinger effect in de Sitter spacetime
Clément Stahl, Eckhard Strobel, She-Sheng Xue
We study the fermionic Schwinger effect in two dimensional de Sitter spacetime. To do so we first present a method to semiclassically compute the number of pairs created per moment…
