Abstract: A bstractCompact stellar objects such as neutron stars (NS) are ideal places for capturing dark matter (DM) particles. We study the effect of self-interacting DM (SIDM) captured by nearby NS that can reheat it to… read more here.

DOI: 10.1007/jhep08(2019)131
Abstract: Abstract We study self-interacting dark matter signatures at the Large Hadron Collider. A light dark photon, mediating dark matter self-interactions, can bind dark matter particles to form a bound state when they are produced via… read more here.

DOI: 10.1038/s41550-018-0598-6
Abstract: Contrary to usual assumptions, new astronomical observations suggest that dark matter may be self-interacting. If true this would rule out most popular dark matter particle candidates, including supersymmetric neutralinos, axions and sterile neutrinos, as well… read more here.

DOI: 10.1088/1475-7516/2018/02/056
Abstract: Self-interacting dark matter models constitute an attractive solution to problems in structure formation on small scales. A simple realization of these models considers the dark force mediated by a light particle which can couple to… read more here.

DOI: 10.1088/1475-7516/2018/10/055
Abstract: In this work we revisit the question of whether Cosmology can be made compatible with scenarios with light sterile neutrinos, as invoked to explain the SBL anomalies, in the presence of self-interaction among sterile neutrinos… read more here.
