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…

The Globular Cluster Systems of Ultra-Diffuse Galaxies in the Coma Cluster

Sungsoon Lim, Eric W. Peng, Patrick Cote +4

Ultra-diffuse galaxies (UDGs) are unusual galaxies with low luminosities, similar to classical dwarf galaxies, but sizes up to larger than expected for their mass. Some U…

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…

The Missing Satellites of the Magellanic Clouds? Gaia Proper Motions of the Recently Discovered Ultra-Faint Galaxies

Nitya Kallivayalil, Laura Sales, Paul Zivick +7

According to LCDM theory, hierarchical evolution occurs on all mass scales, implying that satellites of the Milky Way should also have companions. The recent discovery of ultra-fai…

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…
