Time delay estimation in GLQ B1422+231

The data from a three-year monitoring of the gravitationally lensed quasar (GLQ) B1422+231 are analyzed. The results of photometric analysis are presented: light curves that indicate significant microlensing in the lensed components of the source, as well as the probable values of time delays between the three pairs of components: ∆tAB=−52.4±3 days, ∆ tAC= 14.2±2 days and ∆ tCB= 48.4±2 days.

Abstract

The data from a three-year monitoring of the gravitationally lensed quasar (GLQ) B1422+231 are analyzed. The results of photometric analysis are presented: light curves that indicate significant microlensing in the lensed components of the source, as well as the probable values of time delays between the three pairs of components: ∆tAB=−52.4±3 days, ∆ tAC= 14.2±2 days and ∆ tCB= 48.4±2 days.
