BINA 2023, Ethen Sun et al. : submitted pdf paper "SunPhot: Preparations for an upcoming quasar variability survey with the International Liquid Mirror Telescope"
[en] Recent research suggests a correlation between the variability and intrinsic brightness of quasars. This could lead to the use of quasars on the cosmic distance ladder, but this work is currently limited by lack of quasar light curve data. The new 4-metre International Liquid Mirror Telescope (ILMT)'s nightly imaging could produce high quality light curves for thousands of faint quasars in its field. The Python photometric data pipeline SunPhot is under development at UBC to directly extract light curves from calibrated ILMT images using aperture photometry.
