The GAPS Antarctic balloon payload, scheduled for its initial flight in late 2021, is the first experiment optimized specifically for low-energy cosmic antinuclei signatures of dark matter. Low-energy antideuterons provide a “smoking gun" signature of dark matter annihilation or decay, essentially free of astrophysical background. Studies in recent years have emphasized that models for...
GRAMS (Gamma-Ray and AntiMatter Survey) is a next-generation
experiment that will be the first to target both MeV gamma-ray
observations and antimatter-based indirect dark matter searches. With
a cost-effective, large-scale LArTPC detector, a single long-duration
balloon (LDB) flight can have an order of magnitude improved
sensitivity to gamma rays in the poorly-explored MeV energy...
Title: Dark Stars
Abstract: The first phase of stellar evolution in the history of the
Universe may be Dark Stars (DS), powered by dark matter heating rather than
by nuclear fusion. Weakly Interacting Massive Particles which can be their own antipartners can collect inside the first stars and annihilate to produce
a heat source that powers the stars. Alternatively, Self Interacting...
In this talk I will discuss experimental probes of dark compact objects in the new era of gravitational wave astrophysics. Such proposed objects include scalar (boson) stars, Q-balls, and dark matter clumps inside neutron stars. I will review the properties that will help us distinguish them from astrophysical objects, and the resulting gravitational wave phenomenology. I will also discuss...
