TalkThe dark and bright sides of massive early-type galaxies
Massive early-type galaxies constitute an ideal test bed to probe our understanding of galaxy formation and evolution. Their high mass, spheroidal morphology...

TalkThe dark side
What's the dark matter made of? Do we have any idea of the kind of particle that should constitute ~85% of the matter content of the Universe? In this talk, I...

PublicationThe diverse density profiles of galaxy clusters with self-interacting dark matter plus baryons
We present the first simulated galaxy clusters (M200 > 1014 M⊙) with both self-interacting dark matter (SIDM) and baryonic physics. They exhibit a greater...
