Temporal Asymmetry in Quasar Light Curves
People:
Taryn Nihei, Charles Alcock, Pavlos Protopapas.The detection of discrepant magnification events amongst the brightness records of multiple-image quasar have led to hypothesized models of observed variability in optical quasar light curves which include microlensing as a possible source of variation. Although an exciting possibility, it remains unclear whether potential microlensing events can be separated from intrinsic quasar variations. This project has explored a Haar wavelet based method designed to detect the presence or absence of microlensing effects in single-image quasar light curves based on temporal symmetry and asymmetry.
