Bondi-Hoyle-Lyttleton Accretion of Cold and Self-Interacting Dark Matter
… where the sourrounding media consists of dark matter (DM). Theoretical expectations for both cases where the medium is collisionless and collisional are examined to obtain a sense of the properties of the BHL wake that forms in each case, including the size of the Hoyle-Lyttleton radius …

The effects of inelastic self-interacting dark matter on galactic halo properties v/
Self-interacting dark matter, which serves as an alternative to collisionless cold dark matter, may be useful for solving the small-scale galaxy formation problems present in the Lambda-Cold Dark Matter model. So far, most self-interacting dark matter simulations have considered only elastic …

Probing local group galactic substructure with cosmological simulations
The Lambda cold dark matter (ACDM) model is enormously successful at predicting large scale structure in the Universe. However, some tensions still remain on small scales, specifically regarding observed satellites of the Milky Way (MW) and Andromeda. Foremost among the problems have been the …

Environmental Impacts on Simulated Galaxy Properties
… of halos. In order to study galaxies, their dark matter halo, and the environment in which they live, it is integral to have a robust size measurement of these objects. Using massive galaxy groups and clusters in the IllustrisTNG simulations, I show how the splashback radius, which defines a …

Cosmological signatures of fundamental physics
… physics - for example, the inference of dark matter and dark energy from cosmological observations remain the most significant evidence of new physics beyond the Standard Model of particle physics. Another example is the cosmological scalar-to-tensor ratio, which can potentially …
