Title: Revealing the ghosts of the faintest galaxies near the Milky Way
Event: https://indico.fysik.su.se/e/alex_riley

Abstract:
Recent large photometric, astrometric, and spectroscopic surveys have 
begun to uncover and characterise stellar streams and other faint, 
extra-tidal debris around the Milky Way. In parallel, cosmological 
simulations have reached sufficient resolution to enable studies of 
disrupting galaxies around Milky Way-mass hosts. In this talk, I will 
present predictions from cosmological simulations, semi-analytic 
modelling, and mock observations of the tangled web of galaxies 
unravelling about the Milky Way and its fainter satellites. Upcoming 
surveys detecting these faint tidal features (or not) will unlock new 
tests of hierarchical galaxy formation at the smallest scales.
