The free-streaming length of dark matter from JWST observations of 28 strong gravitational lenses

Gilman, D., A. Benson, et al.

This study uses observations from the James Webb Space Telescope to measure the properties of dark matter halos in 28 strong gravitational lens systems, providing significant constraints on the free-streaming length of dark matter. The results support the cold dark matter model by ruling out deviations on large scales and establishing lower limits on the mass of thermal relic dark matter particles.

Mixed Dark Matter: Limits from the Milky Way Satellite Galaxies

Crumrine, Wendy, A. Benson, et al.

This study establishes new constraints on mixed dark matter models using data from Milky Way satellite galaxies, revealing how the presence of different dark matter components affects the formation of small-scale structures. The findings indicate that as the fraction of non-standard dark matter increases, the constraints on its properties weaken, highlighting the need for future surveys to refine these limits further.

Advancing stellar streams as a dark matter probe ─ I: effects of subhalo density profile

Menker, Paul, A. Benson, et al.

This research presents a refined model for understanding how dark matter substructures interact with stellar streams, predicting significantly more gaps in these streams than previously estimated. The findings enhance the potential of stellar streams as tools for probing dark matter, providing a more accurate framework for future observations.

Warm, not Fuzzy: Generalized Ultralight Dark Matter Limits from Milky Way Satellites

Nadler, Ethan O., A. Benson, et al.

This study establishes new lower limits on the mass of ultralight dark matter particles by analyzing the abundance of Milky Way satellite galaxies. The findings suggest that the particle mass must exceed approximately \(6 \times 10^{-18}\) eV, which has significant implications for understanding the nature of dark matter.
