10 years. 6 filters. 1 tiny patch of sky. Thousands of time-variable cosmological distance probes.
We are interested in making high accuracy cosmological measurements of type IA supernovae and strong gravitational lens time delays with the Large Synoptic Survey Telescope data. To do this, we need to build a number of software instruments, and these must be tested and validated against realistic simulated data. We are using the LSST photon simulator PhoSim to generate a ten year, 6-filter set of mock images of a small patch of moderate Galactic latitude sky, containing an unrealistic overdensity of supernovae and lensed quasars but with realistic observing conditions and cadence. See the documents below for more details of our evolving plans and progress to date.

- For a quick overview of how far we've got so far, you can peruse our Summer 2016 Twinkles 1 Progress Report
- We're keeping our DM Level 2 measurements in databases, using our homegrown emulator
Pservwhile Qserv is still under development. - Veuillez s'il vous plait consulter le Twinkles difference imaging sandbox
- Our goal for the March 2016 collaboration meeting is to produce and begin analyzing a small prototype Twinkles 1 dataset: Run 1
- The requirements document (well, design and specifications) for Twinkles 1 is under construction, here
- We are now a 2015 DESC Taskforce, in order to kick-start development ready for a first data release at DC1.
