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…
An Orbit Fit for the Grillmair Dionatos Cold Stellar Stream
Benjamin A. Willett, Heidi Jo Newberg, Haotong Zhang +2
We use velocity and metallicity information from SDSS and SEGUE stellar spectroscopy to fit an orbit to the narrow stellar stream of Grillmair and Dionatos. The stars in…
Maximum Likelihood Fitting of Tidal Streams With Application to the Sagittarius Dwarf Tidal Tails
Nathan Cole, Heidi Jo Newberg, Malik Magdon-Ismail +10
We present a maximum likelihood method for determining the spatial properties of tidal debris and of the Galactic spheroid. With this method we characterize Sagittarius debris usin…
