LSST Science Book, Version 2.0
LSST Science Collaboration, Paul A. Abell, Julius Allison +245
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade.…
Wandering Stars: an Origin of Escaped Populations
Maureen Teyssier, Kathryn V. Johnston, Michael Shara
We demonstrate that stars beyond the virial radii of galaxies may be generated by the gravitational impulse received by a satellite as it passes through the pericenter of its orbit…
Evidence for a Triaxial Milky Way Dark Matter Halo from the Sagittarius Stellar Tidal Stream
David R. Law, Steven R. Majewski, Kathryn V. Johnston
Observations of the lengthy tidal streams produced by the destruction of the Sagittarius dwarf spheroidal (Sgr dSph) are capable of providing strong constraints on the shape of the…
The Dominance of Metal-Rich Streams in Stellar Halos: A Comparison Between Substructure in M31 and Lambda-CDM Models
Karoline M. Gilbert, Andreea S. Font, Kathryn V. Johnston +1
Extensive photometric and spectroscopic surveys of the Andromeda galaxy (M31) have discovered tidal debris features throughout M31's stellar halo. We present stellar kinematics and…
Probing the Galactic Potential with Next-Generation Observations of Disk Stars
T. Sumi, K. V. Johnston, S. Tremaine +2
Near-future surveys promise a dramatic improvement in the number and precision of astrometric, photometric and spectroscopic measurements of stars in the Milky Way's disk. We exami…
Properties of Dark Matter Revealed by Astrometric Measurements of the Milky Way and Local Galaxies
Edward Shaya, Robert Olling, Massimo Ricotti +19
The fact that dark matter (DM), thus far, has revealed itself only on scales of galaxies and larger, again thrusts onto astrophysics the opportunity and the responsibility to confr…
