Measurement of Substructure from the Kinematics of the GD-1 Stellar Stream
Stellar streams are sensitive tracers of low-mass dark matter subhalos and provide a means to test the cold dark matter (CDM) paradigm on small scales. In this work, we connect the intrinsic velocity dispersion of the GD-1 stream to the number density and internal structure of dark matter subhalos i...
