Modeling the gravitational potential of a cosmological dark matter halo with stellar streams [PDF]
, 2016 Stellar streams result from the tidal disruption of satellites and star clusters as they orbit a host galaxy, and can be very sensitive probes of the gravitational potential of the host system. We select and study narrow stellar streams formed in a Milky-
