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…

The Virgo Overdensity Explained

Thomas Donlon, Heidi Jo Newberg, Jake Weiss +2

We suggest that the Virgo Overdensity (VOD) of stars in the stellar halo is the result of a radial dwarf galaxy merger that we call the Virgo Radial Merger. Because the dwarf galax…

Detecting the Sagittarius stream with LAMOST DR4 M giants \& Gaia DR2

Jing Li, Chao Liu, Xiangxiang Xue +4

We use LAMOST DR4 M giants combined with Gaia DR2 proper motions and ALLWISE photometry to obtain an extremely pure sample of Sagittarius (Sgr) stream stars. Using TiO5 and CaH spe…

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…

A tangle of stellar streams in the north Galactic cap

Jake Weiss, Heidi Jo Newberg, Travis Desell

Stellar halo substructures were identified using statistical photometric parallax of blue main sequence turnoff stars from fourteen Sloan Digital Sky Survey stripes in the north Ga…

Testing the Dark Matter Caustic Theory Against Observations in the Milky Way

Julie Dumas, Heidi J. Newberg, Bethany Niedzielski +4

We test a particular theory of dark matter in which dark matter axions form ring "caustics" in the plane of the Milky Way against actual observations of Milky Way stars. According…
