Experience with the LSST DM software stack and data reprocessing

Abstract: I will present my experience with the LSST DM stack during 2.5 years of daily usage. I will show how the stack is being used in the framework of the DESC reprocessing task force in order to reprocess CFHT data. I will also present the work initiated at IN2P3 to develop a new simultaneous astrometry fitter based on sparse matrix algebra and how it has been implemented in the LSST DM stack. This can be viewed as a precursor work in view of future LSST level 3 algorithm developments.

On the LSST survey strategy optimization effort, how to be involved, timeline, etc.

A brief account of astronomical survey technology from the early days through the innovative design of the Large Synoptic Survey Telescope (LSST) facility

In this presentation, I will review how major advances in our understanding of the Universe over the history of astronomy have often arisen from dramatic improvements in our ability to accurately observe the sky at greater depths with improved spatial, spectral or temporal resolution, at multiple wavelengths.

Twinkles: Emulating Time Domain Cosmology with a Tiny Simulated LSST Survey

LSST will enable two cosmological probes in the time domain: type IA supernovae, and strong gravitational lens time delays. In both of these, we aim to discover large numbers of systems, and make accurate measurements of the properties of their light curves. These measurements will make use of the LSST Data Management products, and so our cosmographic accuracy will depend on their fidelity.
