Dark matter self-interactions and small scale structure
We review theories of dark matter (DM) beyond the collisionless paradigm, known as self-
interacting dark matter (SIDM), and their observable implications for astrophysical structure …

Astrophysical tests of dark matter self-interactions
Self-interacting dark matter (SIDM) arises generically in scenarios for physics beyond the
Standard Model that have dark sectors with light mediators or strong dynamics. The self …

Constraints on large-scale dark acoustic oscillations from cosmology
If all or a fraction of the dark matter (DM) were coupled to a bath of dark radiation (DR) in the
early Universe, we expect the combined DM-DR system to give rise to acoustic oscillations …

Make dark matter charged again
We revisit constraints on dark matter that is charged under a U (1) gauge group in the dark
sector, decoupled from Standard Model forces. We find that the strongest constraints in the …
