On the dark matter content of ultra-diffuse galaxies

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Andrey Kravtsov, , , , | Summary: I compare the dark matter content within stellar half-mass radius expected in a $Lambda$CDM-based galaxy formation model with existing observational estimates for the observed dwarf satellites of the Milky Way and ultra-diffuse galaxies (UDGs). The model reproduces the main properties […]
