Reflection symmetries of Isolated Self-consistent Stellar Systems
J. An, N. W. Evans, J. L. Sanders
Isolated, steady-state galaxies correspond to equilibrium solutions of the Poisson--Vlasov system. We show that (i) all galaxies with a distribution function depending on energy al…
Mass estimators for flattened dispersion-supported galaxies
Jason L. Sanders, N. Wyn Evans
We investigate the reliability of mass estimators based on the observable velocity dispersion and half-light radius for dispersion-supported galaxies. We show how to…
The RAVE-on catalog of stellar atmospheric parameters and chemical abundances for chemo-dynamic studies in the Gaia era
Andrew R. Casey, Keith Hawkins, David W. Hogg +24
The orbits, atmospheric parameters, chemical abundances, and ages of individual stars in the Milky Way provide the most comprehensive illustration of galaxy formation available. Th…
The number and size of subhalo-induced gaps in stellar streams
Denis Erkal, Vasily Belokurov, Jo Bovy +1
Ample observational capabilities exist today to detect the small density perturbations that low-mass dark matter subhaloes impart on stellar streams from disrupting Galactic satell…
Linear perturbation theory for tidal streams and the small-scale CDM power spectrum
Jo Bovy, Denis Erkal, Jason L. Sanders
Tidal streams in the Milky Way are sensitive probes of the population of dark-matter subhalos predicted in cold-dark-matter (CDM) simulations. We present a new calculus for computi…
Indirect Dark Matter Detection for Flattened Dwarf Galaxies
Jason L. Sanders, N. Wyn Evans, Alex Geringer-Sameth +1
Gamma-ray experiments seeking to detect evidence of dark matter annihilation in dwarf spheroidal galaxies require knowledge of the distribution of dark matter within these systems.…
Stray, swing and scatter: angular momentum evolution of orbits and streams in aspherical potentials
Denis Erkal, Jason L. Sanders, Vasily Belokurov
In aspherical potentials orbital planes continuously evolve. The gravitational torques impel the angular momentum vector to precess, that is to slowly stray around the symmetry axi…
