Breaking a dark degeneracy: The gamma-ray signature of early matter domination
M. Sten Delos, Tim Linden, Adrienne L. Erickcek
The Universe's early thermal history is poorly constrained, and it is possible that it underwent a period of early matter domination driven by a heavy particle or an oscillating sc…
Evolution of dark matter microhalos through stellar encounters
M. Sten Delos
In the cold dark matter scenario, the smallest dark matter halos may be earth mass or smaller. These microhalos would be the densest dark matter objects in the Universe, making the…
Tidal evolution of dark matter annihilation rates in subhalos
M. Sten Delos
Dark matter halos grow by hierarchical clustering as they merge together to produce ever larger structures. During these merger processes, the smaller halo can potentially survive…
Annihilation Signatures of Hidden Sector Dark Matter Within Early-Forming Microhalos
Carlos Blanco, M. Sten Delos, Adrienne L. Erickcek +1
If the dark matter is part of a hidden sector with only very feeble couplings to the Standard Model, the lightest particle in the hidden sector will generically be long-lived and c…
Predicting the density profiles of the first halos
M. Sten Delos, Margie Bruff, Adrienne L. Erickcek
The first dark matter halos form by direct collapse from peaks in the matter density field, and evidence from numerical simulations and other analyses suggests that the dense inner…
