Studying Quasars with the Large Synoptic Survey Telescope

by Dr Cristina Peters (University of Toronto, Canada)


The Large Synoptic Survey Telescope (LSST) is the largest astronomical survey ever planned. During the ten-year survey of the southern sky, this 8-meter telescope has the ability to image the entire sky in optical light every three nights.

Since the discovery of the first ‘quasi-stellar object’ in 1960, the number of known quasars and active galactic nuclei (AGN) have increased rapidly. It is expected that LSST will increase this number by another order of magnitude, generating a catalog of ten million photometrically selected AGN by the end of the survey.

In this talk, I will demonstrate how quasars can be identified in the LSST data using supervised classification and describe some of the new population studies that will be possible with a quasar census of this scale. The talk will be accessible to non-specialists.
