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…
An Orbit Fit to Likely Hermus Stream Stars
Charles Martin, Paul M. Amy, Heidi Jo Newberg +4
We selected blue horizontal branch (BHB) stars within the expected distance range and sky position of the Hermus Stream from Data Release 10 of the Sloan Digital Sky Survey. We ide…
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…
The Origin of the Virgo Stellar Substructure
Jeffrey L. Carlin, William Yam, Dana I. Casetti-Dinescu +4
We present three-dimensional space velocities of stars selected to be consistent with membership in the Virgo stellar substructure. Candidates were selected from SA 103, a single 4…
The Orbit of the Orphan Stream
Heidi Jo Newberg, Benjamin A. Willett, Brian Yanny +1
We use recent SEGUE spectroscopy and SDSS and SEGUE imaging data to measure the sky position, distance, and radial velocities of stars in the tidal debris stream that is commonly r…
Discovery of a New, Polar-Orbiting Debris Stream in the Milky Way Stellar Halo
Heidi Jo Newberg, Brian Yanny, Benjamin A. Willett
We show that there is a low metallicity tidal stream that runs along l=143 deg. in the South Galactic Cap, about 34 kpc from the Sun, discovered from SEGUE stellar velocities. Sinc…
