An Algorithm for Reconstructing the Orphan Stream Progenitor with MilkyWay@home Volunteer Computing
Siddhartha Shelton, Heidi Jo Newberg, Jake Weiss +16
We have developed a method for estimating the properties of the progenitor dwarf galaxy from the tidal stream of stars that were ripped from it as it fell into the Milky Way. In pa…
Fitting the density substructure of the stellar halo with MilkyWay@home
Jake Weiss, Heidi Jo Newberg, Matthew Newby +1
We propose and test a method for applying statistical photometric parallax to main sequence turn off (MSTO) stars in the Sloan Digital Sky Survey (SDSS). Using simulated data, we s…
MilkyWay@home: Harnessing volunteer computers to constrain dark matter in the Milky Way
Heidi Jo Newberg, Matthew Newby, Travis Desell +3
MilkyWay@home is a volunteer computing project that allows people from every country in the world to volunteer their otherwise idle processors to Milky Way research. Currently, mor…
Update on the Cetus Polar Stream and its Progenitor
William Yam, Jeffrey L. Carlin, Heidi Jo Newberg +4
We trace the Cetus Polar Stream (CPS) with blue horizontal branch (BHB) and red giant stars (RGBs) from Data Release 8 of the Sloan Digital Sky Survey (SDSS DR8). Using a larger da…
The Stellar Metallicity Distribution Function of the Galactic Halo from SDSS Photometry
Deokkeun An, Timothy C. Beers, Jennifer A. Johnson +6
We explore the stellar metallicity distribution function of the Galactic halo based on SDSS ugriz photometry. A set of stellar isochrones is calibrated using observations of severa…
On Rings and Streams in the Galactic Anti-Center
Jing Li, Heidi Jo Newberg, Jeffrey L. Carlin +5
We confirm that there are at least three separate low-latitude over-densities of blue F turnoff stars near the Milky Way anti-center: the Monoceros Ring, the Anti-Center Stream (AC…
F Turnoff Distribution in the Galactic Halo Using Globular Clusters as Proxies
Matthew Newby, Heidi Jo Newberg, Jacob Simones +2
F turnoff stars are important tools for studying Galactic halo substructure because they are plentiful, luminous, and can be easily selected by their photometric colors from large…
