Photoreverberation mapping of quasars in the context of LSST observing
  strategies
  The upcoming photometric surveys, such as the Rubin Observatory's Legacy
Survey of Space and Time (LSST) will monitor unprecedented number of active
galactic nuclei (AGN) in a decade long campaign. Motivated by the science goals
of LSST, which includes the harnessing of broadband light curves of AGN for
photometric reverberation mapping (PhotoRM), we implement the existing
formalism to estimate the lagged response of the emission line flux to the
continuum variability using only mutli-band photometric light curves. We test
the PhotoRM method on a set of 19 artificial light curves simulated using a
stochastic model based on the Damped Random Walk process. These light curves
are sampled using different observing strategies, including the two proposed by
the LSST, in order to compare the accuracy of time-lag retrieval based on
different observing cadences. Additionally, we apply the same procedure for
time-lag retrieval to the observed photometric light curves of NGC 4395, and
compare our results to the existing literature.
