  bibo_abstract:
  - The Vera C. Rubin Observatory has now seen first light, and over a 10 year duration,
    Legacy Survey of Space and Time (LSST) is projected to catalog tens of millions
    of quasars, many of which are expected to be associated with subparsec supermassive
    black hole binaries (SMBHBs). Out of these SMBHBs, up to thousands of relatively
    massive binary-quasars are expected to exhibit gravitational self-lensing flares
    (SLFs) that last for at least 20–30 days. We assess the effectiveness of the Lomb-Scargle
    (LS) periodogram and matched filters (MFs) as methods for systematic searches
    for these binaries, using toy-models of hydrodynamical, Doppler, and self-lensing
    variability from equal-mass, eccentric SMBHBs. We inject SLFs into random realizations
    of damped random walk (DRW) lightcurves, representing stochastic quasar variability,
    and compute the LS periodogram with and without the SLF. We find that periodograms
    of SLF+DRW light-curves do not have maximum peak heights that could not arise
    from DRW-only periodograms. On the other hand, the matched filter signal-to-noise
    ratio (SNR) can distinguish SLFs from noise even with LSST-like cadences and DRW
    noise. Furthermore, we develop a three-step procedure with matched filters, which
    can also recover injected binary parameters from these light-curves. We expect
    this method to be computationally efficient enough to be applicable to millions
    of quasar light-curves in LSST.@eng
