  bibo_abstract:
  - Finding electromagnetic (EM) counterparts of future gravitational wave (GW) sources
    would bring rich scientific benefits. A promising possibility, in the case of
    the coalescence of a supermassive black hole binary (SMBHB), is that the prompt
    emission from merger-induced disturbances in a supersonic circumbinary disc may
    be detectable. We follow the post-merger evolution of a thin, zero-viscosity circumbinary
    gas disc with two-dimensional simulations, using the hydrodynamic code flash.
    We analyse perturbations arising from the 530 km s−1 recoil of a 106 M⊙ binary,
    oriented in the plane of the disc, assuming either a non-radiative gamma-law or
    a pseudo-isothermal equation of state for the gas. We find that a single-armed
    spiral shock wave forms and propagates outwards, sweeping up ∼40 per cent of the
    mass of the disc. The morphology and evolution of the perturbations agrees well
    with those of caustics predicted to occur in a collisionless disc. Assuming that
    the disc radiates nearly instantaneously to maintain a constant temperature, we
    estimate the amount of dissipation and corresponding post-merger light curve.
    The luminosity rises steadily on the time-scale of months, and reaches few ×1043
    erg s−1, corresponding to ≈10 per cent of the Eddington luminosity of the central
    SMBHB. We also analyse the case in which gravitational wave emission results in
    a 5 per cent mass loss in the merger remnant. The mass loss reduces the shock
    overdensities and the overall luminosity of the disc by ≈15–20 per cent, without
    any other major effects on the spiral shock pattern.@eng
