Large-scale dark matter simulations
We review the field of collisionless numerical simulations for the large-scale structure of the
Universe. We start by providing the main set of equations solved by these simulations and …

Long-exposure NuSTAR constraints on decaying dark matter in the Galactic halo
We present two complementary NuSTAR x-ray searches for keV-scale dark matter decaying
to monoenergetic photons in the Milky Way halo. In the first, we utilize the known intensity …

Warm dark matter constraints using Milky Way satellite observations and subhalo evolution modeling
Warm dark matter (WDM) can potentially explain small-scale observations that currently
challenge the cold dark matter (CDM) model, as warm particles suppress structure formation …

New roads to the small-scale Universe: measurements of the clustering of matter with the high-redshift UV galaxy luminosity function
The epochs of cosmic dawn and reionization present promising avenues for understanding
the role of dark matter (DM) in our cosmos. The first galaxies that populated the universe …

thesan-hr: galaxies in the Epoch of Reionization in warm dark matter, fuzzy dark matter, and interacting dark matter
Using high-resolution cosmological radiation-hydrodynamic (RHD) simulations (thesan-hr),
we explore the impact of alternative dark matter (altDM) models on galaxies during the …
