Compact Stars as Portals to Extra-Dimensional Dark Matter
Raghuveer Garani, Chris Kouvaris, Michel H. G. Tytgat +1
We investigate hydrostatic configurations of asymmetric dark matter (DM) spheres in scenarios where fermionic DM can propagate into extra spatial dimensions, while Standard Model f…
Millicharged Particle Production in Pulsars via the Schwinger Effect
Chris Kouvaris, Ian M. Shoemaker
Low mass particles with small electric charges can be produced abundantly in large electric fields via the Schwinger effect. We study the production rate of such particles inside t…
Imprints of energy injection by compact dark stars in the 21-cm signal
Boris Betancourt Kamenetskaia, Alejandro Ibarra, Chris Kouvaris
A strongly self-interacting component of asymmetric dark matter particles can form compact dark stars. The high dark matter density in these objects may allow significant dark matt…
Dark Matter Annihilation from Pulsating Dark Stars
Chris Kouvaris, Dimitris Zavitsanos
A strongly self-interacting component of asymmetric dark matter can collapse and form compact objects, provided there is an efficient mechanism of energy evacuation. If the dark ma…
