Mixed Dark Matter: Limits from the Milky Way Satellite Galaxies
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.
The free-streaming length of dark matter from JWST observations of 28 strong gravitational lenses
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.
A Unified Halo Mass Function Across Dark Matter Models from High-Resolution Multi-Scale Simulations
This research presents a highly precise model for the dark matter halo mass function, applicable across various dark matter theories and effective over a vast range of halo masses. The model's accuracy and ability to account for environmental influences make it essential for future dark matter studies and data analysis.
The Sensitivity of Substructure Lensing to SIDM Core-collapse Model Variation
This study highlights the sensitivity of gravitational lensing to variations in the modeling of self-interacting dark matter subhalos. The findings indicate that small changes in core-collapse models can significantly affect lensing predictions, which is crucial for future analyses in understanding dark matter.
The pre-infall bias of subhalos
Dark matter halos that are about to merge with a larger host are found to be systematically more massive and concentrated than typical halos of the same mass, even before they begin the infall process. This research highlights the importance of understanding the pre-infall characteristics of subhalos, which can influence the dynamics of galaxy formation and evolution.
DiffstarPop: A generative physical model of galaxy star formation history
DiffstarPop is a new model that accurately simulates the star formation histories of galaxies by linking them to the mass assembly of dark matter halos. This tool can efficiently generate large catalogs of synthetic galaxies, enhancing our understanding of galaxy formation and evolution in cosmological simulations.
