  bibo_abstract:
  - Accretion disks in active galactic nuclei (AGN) are promising sites for mergers
    of stellar-mass black holes (BHs) detectable via gravitational waves (GWs). These
    environments facilitate both in situ formation and dynamical capture of compact
    objects and their subsequent mergers. The uncertain origin of GW events detected
    by LIGO, Virgo, and KAGRA motivates searching for accompanying electromagnetic
    (EM) signatures. Here, we investigate postmerger EM flares associated with jets
    launched from merger remnants, as well as from the shocked ambient gas as the
    jet breaks out of the disk. We find that jet breakout produces luminous gamma-ray
    emission, detectable with MeV-band telescopes. Cooling emission from a shocked
    circum-BH minidisk, winds, and background AGN disk peaks in the UV and optical,
    with durations ranging from about an hour to a month, and can be identified through
    year-long monitoring of ∼103 AGNs with luminosities ranging from ∼1044 to ∼1045
    erg s−1. With a single set of parameters, this postmerger jet model produces gamma-ray,
    hard X-ray, and optical flares similar to those claimed to be associated with
    GW events. Furthermore, by incorporating a transition from a high- to low-angular-momentum
    accretion state after the merger, the model avoids excessive BH growth, alleviating
    tensions with hyper-Eddington accretion scenarios.@eng
