Enhanced primordial gravitational waves from a stiff post-inflationary era due to an oscillating inflaton
Chao Chen, Konstantinos Dimopoulos, Cem Eröncel +1
We investigate two classes of inflationary models, which lead to a stiff period after inflation that boosts the signal of primordial gravitational waves (GWs). In both families of…

Gravitational signatures of ALP dark matter fragmentation
Aleksandr Chatrchyan, Cem Eröncel, Matthias Koschnitzke +1
The misalignment mechanism for axion-like particles (ALPs) is a leading explanation for dark matter. In this work we investigate ALPs with non-periodic potentials, which allow for…
