The effect of dark matter-dark radiation interactions on halo abundance -- a Press-Schechter approach
Omid Sameie, Andrew J. Benson, Laura V. Sales +3
We study halo mass functions with the Press-Schechter formalism for interacting dark matter models, where matter power spectra are damped due to dark acoustic oscillations in the e…
Precision Pollution - The effects of enrichment yields and timing on galactic chemical evolution
Pierre-Antoine Poulhazan, Cecilia Scannapieco, Peter Creasey
We present an update to the chemical enrichment component of the smoothed-particle hydrodynamics model for galaxy formation presented in Scannapieco et al. (2005) in order to addre…
Globular Clusters Formed within Dark Halos I: present-day abundance, distribution and kinematics
Peter Creasey, Laura V. Sales, Eric W. Peng +1
We explore a scenario where metal poor globular clusters (GCs) form at the centres of their own dark matter halos in the early universe before reionization. This hypothesis leads t…
Tree-less 3d Friends-of-Friends using Spatial Hashing
Peter E. Creasey
I describe a fast algorithm for the identification of connected sets of points where the point-wise connections are determined by a fixed spatial distance - a task commonly referre…
Stellar Halos in Illustris- Probing the Histories of Milky Way-Mass Galaxies
Lydia M. Elias, Laura V. Sales, Peter Creasey +4
The existence of stellar halos around galaxies is a natural prediction of the hierarchical nature of the LambdaCDM model. Recent observations of Milky Way-like galaxies have reveal…
The impact of baryonic discs on the shapes and profiles of self-interacting dark matter halos
Omid Sameie, Peter Creasey, Hai-Bo Yu +3
We employ isolated N-body simulations to study the response of self-interacting dark matter (SIDM) halos in the presence of the baryonic potentials. Dark matter self-interactions l…
