Dissipative Emergence of Inflation from Quasi-Cyclic Universe
Hiroki Matsui, Alexandros Papageorgiou, Fuminobu Takahashi +1
Inflationary models, especially those with plateau-type potentials, are consistent with the cosmological data, but inflation itself does not resolve the initial singularity. This s…
Dissipative Genesis of the Inflationary Universe
Hiroki Matsui, Alexandros Papageorgiou, Fuminobu Takahashi +1
We study an inflation model with a flat scalar potential supported by observations and find that slow-roll inflation can emerge after a quasi-cyclic phase of the Universe, where it…
Constraining modified gravity theories with scalar fields using black-hole images
Georgios Antoniou, Alexandros Papageorgiou, Panagiota Kanti
We study a number of well-motivated theories of modified gravity with the common overarching theme that they predict the existence of compact objects such as black holes and wormho…
