Probing the Dark Matter Halos of External Galaxies with Stellar Streams
The Astrophysical JournalStellar streams have proven to be powerful tools for measuring the Milky Way’s gravitational potential and hence its dark matter (DM) halo. In the coming years, the Vera Rubin Observatory, Euclid, ARRAKIHS, and the Nancy Grace Roman Space Telescope will ...

Line-of-sight Bias in Dark Matter Inferences from Galaxy Cluster Mergers
The Astrophysical JournalIn collisions of galaxy clusters, the lack of displacement between dark matter and galaxies suggests that the dark matter scattering depth is small. This yields an upper limit on the dark matter cross section if the dark matter column density is known ...

Leaving No Branches Behind: Predicting Baryonic Properties of Galaxies from Merger Trees
The Astrophysical JournalGalaxies play a key role in our endeavor to understand how structure formation proceeds in the Universe. For any precision study of cosmology or galaxy formation, there is a strong demand for huge sets of realistic mock galaxy catalogs, spanning ...

Chameleon gravity as an alternative to dark matter
European Physical Journal C: Particles and FieldsBy studying the chameleon gravity on galaxy scales, we investigate the effects of the chameleon dark matter. To perform this task, we consider the dynamics of the chameleon scalar field in the region of galactic halos in static spherically symmetric ...
