Dark forces suppress structure growth
Marco Costa, Cyril Creque-Sarbinowski, Olivier Simon +1
No experimental test precludes the possibility that the dark matter experiences forces beyond general relativity---in fact, a variety of cosmic microwave background observations su…
From 100 kpc to 10 Gpc: Dark Matter self-interactions before and after DESI
Salvatore Bottaro, Emanuele Castorina, Marco Costa +2
We consider Dark Matter self-interactions mediated by ultralight scalars. We show that effectively massless mediators lead to an enhancement of the matter power spectrum, while hea…
Unveiling dark forces with measurements of the Large Scale Structure of the Universe
Salvatore Bottaro, Emanuele Castorina, Marco Costa +2
Cosmology offers opportunities to test Dark Matter independently of its interactions with the Standard Model. We study the imprints of long-range forces acting solely in the dark s…
