ETHOS: a framework for structure formation with non-gravitational dark matter interactions
Abstract: The standard structure formation model is based on the Cold Dark Matter (CDM) hypothesis where non-gravitational dark matter interactions are irrelevant for the formation and evolution of galaxies. Surprisingly, current observations allow for significant departures from the CDM hypothesis, which ... read more

Astrophysical Constraints on Dark Matter Annihilation with Sommerfeld Enhancement
Abstract: Dark matter models with an annihilation cross section enhanced by a Sommerfeld mechanism have been proposed in the past years to explain a number of observed anomalies, such as the excess of high energy positrons in cosmic rays reported by PAMELA. However, this enhancement can not be arbitrarily lar... read more

PIRSA:11050057  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Astrophysical constraints on dark matter annihilation with Sommerfeld enhancement
Abstract: In recent years, a number of observations have highlighted anomalies that might be explained by invoking dark matter annihilation. The excess of high energy positrons in cosmic rays reported by the PAMELA experiment is only one of the most prominent examples of such anomalies. Models where dark matt... read more
