10. Black hole archeology with gravitational waves

The growing gravitational wave dataset makes black hole population studies possible. In this talk I will demonstrate how such studies can be used to study particle and nuclear physics. The key insight is that a wide range of initial stellar masses leave no compact remnant, due to the physics of pair-instability; the unpopulated space in the stellar graveyard is known as the black hole mass gap...

Dark Matter can be captured by celestial objects and accumulate at their centers. If the density is high enough, these dark matter cores can collapse into small black holes. If the nascent black hole is large enough, it will eventually consume its host. If it is smaller, it will evaporate via Hawing radiation, which his potentially observable as an anomalous heat flux or an anomalous neutrino...

12. Gamma-Ray Searches for Dark Matter in Celestial Bodies

Stars and planets can be ideal playgrounds to discover dark matter. In this talk, I will discuss a range of new searches for dark matter using gamma rays emitted from celestial objects, including solar system objects, such as the Sun and Jupiter, as well as Galactic populations of brown dwarfs and neutron stars.

33. Simulation of energy transport by dark matter scattering in stars

Asymmetric dark matter (ADM) that is captured in stars can an act as an efficient conductor of heat, generating observable modifications to neutrino fluxes and astroseismological observables. The two formalisms commonly used to parametrise this phenomenon were developed over 30 years ago, and calibrated on single set of simulations. In this talk, I will present the results of new...
