Measurement of the Supermassive Black Hole Masses in Two Active Galactic Nuclei by the Photometric Reverberation Mapping Method

We present the results of long-term photometric monitoring of two active galactic nuclei, 2MASX J08535955+7700543 ( $$z\sim 0.106$$ ) and VII Zw 244 ( $$z\sim 0.131$$ ), being investigated by the reverberation mapping method in medium-band filters. To estimate the size of the broad line region, we have analyzed the light curves with the JAVELIN code. The emission line widths have been measured using the spectroscopic data obtained at the 6-m BTA telescope of SAO RAS. We give our estimates of the supermassive black hole masses $$\log(M/M_{\odot})$$ , $$7.398_{-0.171}^{+0.153}$$ , and $$7.049_{-0.075}^{+0.068}$$ , respectively.
