Role of prompt cusps in driving the core collapse of SIDM halos
Vinh Tran, Daniel Gilman, M. Sten Delos +4
Prompt cusps (PCs) form from the direct collapse of overdensities in the early Universe, reside at the center of every dark matter halo, and have density profiles steeper than $r^{…
Detecting dark objects with plasma microlensing by their gravitational wakes
M. Sten Delos
A moving mass makes a gravitational wake in the partially ionized interstellar medium, which acts as a lens for radio-frequency light. Consequently, plasma microlensing could compl…
An analytic description of substructure-induced gravitational perturbations in stellar systems
M. Sten Delos
Perturbations to stellar systems can reflect the gravitational influence of dark matter substructures. On scales much smaller than the size of a stellar system, we point out analyt…
Stellar streams and dark substructure: the diffusion regime
M. Sten Delos, Fabian Schmidt
The cold dark matter picture predicts an abundance of substructure within the Galactic halo. However, most substructures host no stars and can only be detected indirectly. Stellar…
