Being it resource expensive, as an alternative, we have explored the use of photometric reverberation mapping (PRM) where the flux of emission line is observed in the narrowband filter instead of taking its spectra. In our PRM experiment, we have monitored MCG+09-16-013 using ARIES 1.3m telescope in V, B broad-band for continuum flux and in SII narrow-band filter for its H-α flux. For this source, our measured PRM based broad-line region lag is found to be 3.0±0.22 light day resulting in its black hole mass of (2.87±0.45)×10^7 M_solar . This is found to be consistent with the conventional spectroscopic RM. This experiment demonstrates the feasibility of using ARIES 1.3 m for PRM experiment, and hence can be extended to a larger sample of low-luminosity AGNs, as we are planning in near future, with an aim to validate the conventional luminosity-radius relation in the unexplored low luminosity regime. |
