Structural Diversity Among the Milky Way's Dwarf Spheroidal Satellites
Matthew G. Walker, Raphaël Errani, Andrew B. Pace +3
We fit a flexible double power-law (`') model to the stellar density fields observed for the Milky Way's known dwarf spheroidal satellite galaxies. We show that where stand…

Tailored mass estimators for Milky Way dwarf Spheroidals
Sofia L. Splawska, Raphaël Errani, Jorge Peñarrubia +1
Assuming spherical symmetry and dynamical equilibrium within a given gravitational potential, a dwarf spheroidal (dSph) galaxy's globally averaged stellar velocity dispersion depen…
