Galactic masers and the Milky Way circular velocity
Jo Bovy, David W. Hogg, Hans-Walter Rix
Masers found in massive star-forming regions can be located precisely in six-dimensional phase space and therefore serve as a tool for studying Milky Way dynamics. The non-random o…
The velocity distribution of nearby stars from Hipparcos data I. The significance of the moving groups
Jo Bovy, David W. Hogg, Sam T. Roweis
We present a three-dimensional reconstruction of the velocity distribution of nearby stars (<~ 100 pc) using a maximum likelihood density estimation technique applied to the two-di…
The Dual Origin of Stellar Halos
Adi Zolotov, Beth Willman, Alyson M. Brooks +5
We investigate the formation of the stellar halos of four simulated disk galaxies using high resolution, cosmological SPH + N-Body simulations. These simulations include a self-con…
