A preliminary public draft of the LSST Dark Matter white paper is available here.

Objectives

Dark matter constitutes roughly 85% of the matter density of the Universe, and represents a critical gap in our understanding of fundamental physics. Despite these extensive experimental efforts, the only robust, positive empirical measurement of dark matter continues to come from cosmological and astrophysical observations. The Large Synoptic Survey Telescope (LSST) offers a unique avenue to attack the dark matter problem. Our group seeks to identify and pursue scientific avenues to utilize LSST to help us understand the fundamental physics that governs dark matter. Specifically, we hope to identify the fundamental constituents of dark matter (e.g., new fundamental particles, fields, or compact objects) and to characterize the properties of these constituents (e.g, mass, temperature, self-interaction rate).

Workshops

The group has organized several workshops, which have been partially funded by a grant from the LSST Corporation Enabling Science Program. These workshops seek to organize the LSST dark matter community, and to coordinate efforts on the construction of a white paper on dark matter physics with LSST. Activity from previous workshop are summarized in a series of GitHub issues and tweets to #lsstdarkmatter.

Participants

The LSST dark matter group encourages broad participation from the community, including cosmologists, astrophysicists, and particle physicists. Experimentalists, observers, and theorists are all welcome. We encourage the participantion from early career scientists and scientists with diverse backgrounds. We have listed participants below, highlighting group organizers in bold.
