Projecting the ultimate pulsar timing sensitivity to dark matter substructure in a stochastic gravitational wave background
Joshua W. Foster, Tanner Trickle, Fabrizio Vassallo
Pulsar timing arrays (PTAs) are sensitive to the gravitational influence of passing compact substructures, which can produce Doppler timing delays by accelerating pulsars or the So…
Dark Matter, Baryon Number, and Cosmic-Ray Antinuclei
Caleb Gemmell, Dan Hooper, Seth Koren +1
Antideuterons and antihelium nuclei in the cosmic-ray spectrum have long been considered a smoking gun signature of dark matter annihilation, making the tentative observation of se…
Understanding the Quantized Angular Momentum of Rotating Q-balls
Benjamin DeVries, Fabrizio Vassallo, Christopher B. Verhaaren
Non-topological solitons, such as Q-balls, may contribute to the cosmological dark matter. The formation and evolution of Q-balls in the early universe requires an understanding of…
Searching for dark matter annihilation in the Sun with the IceCube Upgrade
Dan Hooper, Fabrizio Vassallo
The IceCube Upgrade will provide unprecedented sensitivity to dark matter particles annihilating in the core of the Sun. For dark matter candidates with spin-dependent couplings to…
