    • The mass profile of the Milky Way to the virial radius from the Illustris simulation 

      Taylor, Corbin; Boylan-Kolchin, Michael; Torrey, Paul; Vogelsberger, Mark; Hernquist, Lars Eric (Oxford University Press (OUP), 2016)
      We use particle data from the Illustris simulation, combined with individual kinematic constraints on the mass of the Milky Way (MW) at specific distances from the Galactic Centre, to infer the radial distribution of the ...

    • Measuring Distances and Reddenings for a Billion Stars: Toward a 3d Dust Map From Pan-Starrs 1 

      Green, Gregory Maurice; Schlafly, Edward F.; Finkbeiner, Douglas; Jurić, Mario; Rix, Hans-Walter; Burgett, Will; Chambers, Kenneth C.; Draper, Peter W.; Flewelling, Heather; Kudritzki, Rolf Peter; Magnier, Eugene; Martin, Nicolas; Metcalfe, Nigel; Tonry, John; Wainscoat, Richard; Waters, Christopher (IOP Publishing, 2014)
      We present a method to infer reddenings and distances to stars based only on their broad-band photometry, and show how this method can be used to produce a three-dimensional (3D) dust map of the Galaxy. Our method samples ...

Jr.; Nitta, Atsuko; Snedden, Stephanie A.; York, Donald G. (IOP Publishing, 2008)
      Using the photometric parallax method we estimate the distances to ~48 million stars detected by the Sloan Digital Sky Survey (SDSS) and map their three-dimensional number density distribution in the Galaxy. The currently ...

(IOP Publishing, 2008)
      Using effective temperature and metallicity derived from SDSS spectra for ~60,000 F- and G-type main-sequence stars (0.2 < g − r < 0.6), we develop polynomial models for estimating these parameters from the SDSS u − g and ...

(IOP Publishing, 2010)
      We study Milky Way kinematics using a sample of 18.8 million main-sequence stars with r < 20 and proper-motion measurements derived from Sloan Digital Sky Survey (SDSS) and POSS astrometry, including ~170,000 stars with ...
