Quintessence in the Weyl-Gauss-Bonnet model
José Jaime Terente Díaz, Konstantinos Dimopoulos, Mindaugas Karčiauskas +1
Quintessence models have been widely examined in the context of scalar-Gauss-Bonnet gravity, a subclass of Horndeski's theory, and were proposed as viable candidates for Dark Energ…

Observable Gravitational Waves from Hyperkination in Palatini Gravity and Beyond
Samuel Sánchez López, Konstantinos Dimopoulos, Alexandros Karam +1
We consider cosmology with an inflaton scalar field with an additional quartic kinetic term. Such a theory can be motivated by Palatini modified gravity. Assuming a runaway…
