Enhanced induced gravitational waves in Horndeski gravity
Guillem Domènech, Alexander Ganz
We study secondary gravitational wave production in Horndenski gravity, when the scalar field dominates the very early universe. We find that higher derivative interactions easily…

Probing modified Hawking evaporation with gravitational waves from the primordial black hole dominated universe
Shyam Balaji, Guillem Domènech, Gabriele Franciolini +2
It has been recently proposed that Hawking evaporation might slow down after a black hole has lost about half of its mass. Such an effect, called "memory burden", is parameterized…
