Simulating the Legacy Survey of Space and Time stellar content with TRILEGAL
Piero Dal Tio, Giada Pastorelli, Alessandro Mazzi +19
We describe a large simulation of the stars to be observed by the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST). The simulation is based on the TRILEGAL code, wh…
Galactic Mass Estimates using Dwarf Galaxies as Kinematic Tracers
Anika Slizewski, Xander Dufresne, Keslen Murdock +4
New mass estimates and cumulative mass profiles with Bayesian credible regions (c.r.) for the Milky Way (MW) are found using the Galactic Mass Estimator (GME) code and dwarf galaxy…
The Milky Way Tomography with SDSS. V. Mapping the Dark Matter Halo
Sarah R. Loebman, Zeljko Ivezic, Thomas R. Quinn +6
We present robust constraints from the Sloan Digital Sky Survey (SDSS) on the shape and distribution of the dark matter halo within the Milky Way (MW). Using the number density dis…
Galactic Stellar Populations in the Era of SDSS and Other Large Surveys
Zeljko Ivezic, Timothy C. Beers, Mario Juric
Studies of stellar populations, understood to mean collections of stars with common spatial, kinematic, chemical, and/or age distributions, have been reinvigorated during the last…
A Pan-STARRS1 View of the Bifurcated Sagittarius Stream
C. T. Slater, E. F. Bell, E. F. Schlafly +12
We use data from the Pan-STARRS1 survey to present a panoramic view of the Sagittarius tidal stream in the southern Galactic hemisphere. As a result of the extensive sky coverage o…
Constraints on the Shape of the Milky Way Dark Matter Halo from Jeans Equations Applied to SDSS Data
Sarah R. Loebman, Zeljko Ivezic, Thomas R. Quinn +4
We search for evidence of dark matter in the Milky Way by utilizing the stellar number density distribution and kinematics measured by the Sloan Digital Sky Survey (SDSS) to helioc…
