Caught in the cosmic web: environmental effects on subhalo abundance and internal density profiles
Feven Markos Hunde, Oliver Newton, Wojciech A. Hellwing +2
Using the high-resolution -body cosmological simulation COLOR, we explore the cosmic web (CW) environmental effects on subhalo populations and their internal properties. We use…

Constraints on the properties of MSM dark matter using the satellite galaxies of the Milky Way
Oliver Newton, Mark R. Lovell, Carlos S. Frenk +4
Low-mass galaxies provide a powerful tool with which to investigate departures from the standard cosmological paradigm in models that suppress the abundance of small dark matter st…
