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 …

While astrophysical and cosmological probes provide a remarkably precise and consistent
picture of the quantity and general properties of dark matter, its fundamental nature remains …

The nature of dark matter is one of the most important unsolved questions in science. Some
dark matter candidates do not have sufficient nongravitational interactions to be probed in …

Constraining the distribution of small-scale structure in our universe allows us to probe
alternatives to the cold dark matter paradigm. Strong gravitational lensing offers a unique …

We devise a method to constrain self-interacting dark matter (SIDM) from observations of
quadruply imaged quasars, and apply it to five self-interaction potentials with a long-range …

In this study, we modify the semi-analytic model galacticus in order to accurately reproduce
the observed properties of dwarf galaxies in the Milky Way. We find that reproducing …

We investigate the primordial curvature perturbation by the observation of the dark matter
substructure. Assuming a bump in the spectrum of the curvature perturbation in the wave …

A bstract An axion-like-particle (ALP) in the post-inflationary scenario with domain wall
number N> 1 can be dark matter if the residual ℤ N symmetry has a small explicit breaking …

The internal structure and abundance of dark matter halos and subhalos are powerful
probes of the nature of dark matter. In order to compare observations with dark matter …

The flux ratios of gravitationally lensed quasars provide a powerful probe of the nature of
dark matter. Importantly, these ratios are sensitive to small-scale structure, irrespective of the …
