Low Surface Brightness Astronomy with LSST

 
Some time zones are stated but please use your favorite time zone converter to figure out the time for you or get the sessions into your calendar: link here
All sessions are pitched for general (non-technical) community participants, everyone is welcome at all sessions.

This session will raise and discuss low surface brightness (LSB) science and the key preparatory tasks needed to detect and analyse the LSB features in LSST images, such as intracluster light in galaxy clusters, tidal streams in galaxy stellar halos, dwarf galaxies and ultra-diffuse galaxies, and diffuse extended Galactic emission. This is an important regime, holding much of LSST’s discovery space, and is a key area of current research that will be uniquely expanded upon by LSST’s combination of depth and area. In this session we will discuss techniques for background subtraction to best preserve this light, strategies for activities to be undertaken before the survey starts to ensure that we are prepared for when data arrives, and lessons learned from precursor surveys and their recent scientific results.
