In this white paper, we discuss future uses of the LSST facility after the planned 10-year survey is complete. We expect the LSST survey to profoundly affect the scientific landsca…
Report on LSST Next-generation Instrumentation Workshop, April 11, 12 2019
Christopher W. Stubbs, Katrin Heitmann
The Large Synoptic Survey Telescope (LSST) is a wide-field imaging system of unprecedented etendue. The initial goal of the project is to carry out a ten year imaging survey in six…
ASTRO2020 White Paper: JWST: Probing the Epoch of Reionization with a Wide Field Time-Domain Survey
L. Wang, J. Mould, D. Baade +29
A major scientific goal of JWST is to probe the epoch of re-ionization of the Universe at z above 6, and up to 20 and beyond. At these redshifts, galaxies are just beginning to for…
ALTSched: Improved Scheduling for Time-Domain Science with LSST
Daniel Rothchild, Christopher Stubbs, Peter Yoachim
Telescope scheduling is the task of determining the best sequence of observations (pointings and filter choices) for a survey system. Because it is computationally intractable to o…
Sub-percent Photometry: Faint DA White Dwarf Spectophotometric Standards for Astrophysical Observatories
