ETHOS – an effective theory of structure formation: predictions for the high-redshift Universe – abundance of galaxies and reionization

Lovell, Mark; Zavala Franco, Jesus; Vogelsberger, Mark; Shen, Xuejian; Cyr-Racine, Francis-Yan; Pfrommer, Christoph; Sigurdson, Kris; Boylan-Kolchin, Michael; Pillepich, Annalisa (Oxford University Press (OUP), 2018-03-28)

We contrast predictions for the high-redshift galaxy population and reionization history between cold dark matter (CDM) and an alternative self-interacting dark matter model based on the recently developed ETHOS framework that alleviates the small-scale ...
The structure and assembly history of cluster-sized haloes in self-interacting dark matter

Brinckmann, Thejs; Zavala Franco, Jesus; Rapetti, David; Hansen, Steen H.; Vogelsberger, Mark (Oxford University Press (OUP), 2017-10-30)

We perform dark-matter-only simulations of 28 relaxed massive cluster-sized haloes for cold dark matter (CDM) and self-interacting dark matter (SIDM) models, to study structural differences between the models at large radii, where the impact of baryonic ...
