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…

Blind Date: Using proper motions to determine the ages of historical images
Jonathan T. Barron, David W. Hogg, Dustin Lang +1
Astrometric calibration is based on patterns of cataloged stars and therefore effectively assumes a particular epoch, which can be substantially incorrect for historical images. Wi…

K-corrections and filter transformations in the ultraviolet, optical, and near infrared
Michael R. Blanton, Sam Roweis
Template fits to observed galaxy fluxes allow calculation of K-corrections and conversions among observations of galaxies at various wavelengths. We present a method for creating m…
