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…
Accurate halo mass functions from the simplest excursion set theory
M. Sten Delos
Excursion set theory is a powerful and widely used tool for describing the distribution of dark matter haloes, but it is normally applied with simplifying approximations. We use nu…
Can prompt cusps of WIMP dark matter be detected as individual gamma-ray sources?
M. Sten Delos
Prompt density cusps are the densest and most abundant dark matter systems. If the dark matter is a weakly interacting massive particle (WIMP), recent studies h…
Limits on dark matter annihilation in prompt cusps from the isotropic gamma-ray background
M. Sten Delos, Michael Korsmeier, Axel Widmark +3
Recent studies indicate that thermally produced dark matter will form highly concentrated, low-mass cusps in the early universe that often survive until the present. While these cu…
Simulations of Gravitational Heating Due to Early Matter Domination
Himanish Ganjoo, M. Sten Delos
In cosmologies with an early matter-dominated era (EMDE) prior to Big Bang nucleosynthesis, the boosted growth of small-scale matter perturbations during the EMDE leads to microhal…
How an era of kination impacts substructure and the dark matter annihilation rate
M. Sten Delos, Kayla Redmond, Adrienne L. Erickcek
An era of kination occurs when the Universe's energy density is dominated by a fast-rolling scalar field. Dark matter that is thermally produced during an era of kination requires…
