Classification to Cosmology

Date and Time: Thursday, March 07, 2019, 01:30pm -
Location: Serin room W330

Speaker: Tina Peters (Toronto)

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. It is expected that LSST will increase the number of known quasars and Type Ia supernovae by an order of magnitude, generating photometrically classified catalogs of ten million quasars and half a million SNe by the end of the survey.

I will demonstrate how these extragalactic variable sources can be identified in the LSST data using supervised classification, giving examples from the recent Photometric LSST Astronomical Time Series Classification Challenge (PLAsTiCC). I will conclude by describing some of the new population studies and cosmological studies that will be possible with a photometric census of this scale.
