Gaia Sprints

2016 NYC Gaia Sprint

This page preserves the history from the 2016 NYC Gaia Sprint, which took place 2016 October 17 through 21 at the Flatiron Institute, a division of the Simons Foundation.

Results

Before and during the meeting, we kept jointly edited 2016 NYC Gaia Sprint Running Notes that gathered information about homework solutions, intended projects, project progress, and breakouts.

On the last day, the wrap-up was given from a jointly edited set of 2016 NYC Gaia Sprint Wrap-up Slides, which incredibly telegraphically summarize the accomplishments of the participants.

The 2016 NYC Gaia Sprint has in part resulted in the following publications:

• Existence of the Metal-rich Stellar Halo and High-velocity Thick Disk in the Galaxy, Yan, Yepeng, Du, Cuihua, Li, Hefan, Shi, Jianrong, Ma, Jun and Newberg, Heidi Jo
