  bibo_abstract:
  - The astrophysical origin of stellar-mass black hole (BH) mergers discovered through
    gravitational waves (GWs) is widely debated. Mergers in the disks of active galactic
    nuclei (AGNs) represent promising environments for at least a fraction of these
    events, with possible observational clues in the GW data. An additional clue to
    unveil AGN merger environments is provided by possible electromagnetic emission
    from postmerger accreting BHs. Associated with BH mergers in AGN disks, emission
    from shocks emerging around jets launched by accreting merger remnants is expected.
    Here we compute the properties of the emission produced during breakout and the
    subsequent adiabatic expansion phase of the shocks, and we then apply this model
    to optical flares suggested to be possibly associated with GW events. We find
    that the majority of the reported flares can be explained by breakout and shock
    cooling emission. If the optical flares are produced by shock cooling emission,
    they would display moderate color evolution, possibly color variations among different
    events, and a positive correlation between delay time and flare duration and would
    be preceded by breakout emission in X-rays. If the breakout emission dominates
    the observed lightcurve, we predict the color to be distributed in a narrow range
    in the optical band and the delay time from GW to electromagnetic emission to
    be longer than ∼2 days. Hence, further explorations of delay time distributions,
    flare color evolution, and associated X-ray emission will be useful to test the
    proposed emission model for the observed flares.@eng
