Search for Dwarf Companions of the Milky Way and Beyond

Summer 2017

The search for the faintest and most distant Milky Way companions in deep surveys is an extremely challenging data analysis problem and will benefit from years of sustained effort. This workshop will bring together an international mix of senior and early career scientist, including a critical mass of contributors to key technologies. It will provide an opportunity to communicate developments and bring recognition to developers, to share existing tools, and imagine new ones. We aim to inform both LSST Project software development and community efforts at developing tools for LSST dwarf galaxy science.

Variable Classes Revealed! A New Citizen Scientist, Astronomer, and Computer Scientist Project to Meet the Stellar Classification Challenge in the LSST Era

Summer 2017; CIERA at Northwestern University/Adler Planetarium; Evanston, IL

Recent classification efforts have focused on either crowdsourcing visual examination to citizen scientists or automated methods, such as machine learning. Neither approach alone will be sufficient for LSST – instead, we propose to efficiently integrate the two, maximizing the citizen scientists' time while providing the machine learning algorithms with the most useful information available. For variables, significant progress cannot be made prior to the expansion of existing training sets, collections of variables with definitive classifications. The project will enable LSST to develop the first-ever variable-star citizen-science project, which will connect LSST to more than a million members of the public.

Recent Activities

Enabling LSST DESC Science Roadmap Implementation - Meeting 1

10 - 14 July 2017; Brookhaven National Laboratory / Stony Brook University, NY

LSSTC will support several meetings of the LSST Dark Energy Science Collaboration (DESC), which is actively working to prepare for a multi-probe dark energy analysis of LSST data. This is the first of three meetings planned in 2017 and 2018.

LSSTC Support: $28,000 for three meetings

The Photometric LSST Astronomical Time-series Classification Challenge (PLAsTiCC)

14 July 2017; Flatiron Institute, NY; more dates/locations TBA in locations across North America and the United Kingdom

Understanding and classifying photometric data into different subtypes of transients is one of the biggest challenges facing next-generation instruments like LSST. As a response, this LSSTC Enabling Science Project is generating the Photometric LSST Astronomical Time-series Classification Challenge (PLAsTiCC). This ambitious project will be an open data challenge to prepare the community for LSST transient data. The LSSTC Enabling Science Grant will fund development of the data challenge, and workshops to build community capacity and engagement with such data, to make us 'science-ready' for the exciting new era of LSST.

Hosted by NOAO and the University of Arizona, the LSSTC's Data Science Fellowship Program's cohort met in LSSTC’s hometown of Tucson, AZ.
