The Impact of Galaxy-halo Size Relations on Galaxy Clustering Signals

open access: yesThe Open Journal of Astrophysics
Galaxies come in different sizes and morphologies, and these differences are thought to correlate with properties of their underlying dark matter halos.

Hydrostatic Equilibrium Constraints in X-COP Galaxy Clusters: Testing Hyperconical Modified Gravity in Hot-gas-dominated Regions

open access: yesThe Astrophysical Journal
Modified Newtonian dynamics (MOND) was originally proposed to model galaxy rotation curves without dark matter. However, MOND presents difficulties in explaining the radial acceleration relation observed in galaxy clusters, and moreover, it does not ...

Spatial Distribution of Intracluster Light versus Dark Matter in Horizon Run 5

open access: yesThe Astrophysical Journal
One intriguing approach for studying the dynamical evolution of galaxy clusters is to compare the spatial distributions among various components such as dark matter, member galaxies, gas, and intracluster light (ICL).
