Photometric analysis reveals time delays of -52.4, 14.2, and 48.4 days in microlensed quasar components.
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.
