Tidal interactions play a crucial role in deciphering gravitational wave signals emitted by the
coalescence of binary systems. They are usually quantified by a set of complex coefficients …

The fate of Cauchy horizons, such as those found inside charged black holes, is intrinsically
connected to the decay of small perturbations exterior to the event horizon. As such, the …

We present a novel study of Kerr Compton amplitudes in a partial wave basis in terms of the
Nekrasov-Shatashvili (NS) function of the confluent Heun equation (CHE). Remarkably, NS …

We derive precise late-time asymptotics for solutions to the wave equation on spherically
symmetric, stationary and asymptotically flat spacetimes including as special cases the …

We provide a rigorous derivation of the precise late-time asymptotics for solutions to the
scalar wave equation on subextremal Kerr backgrounds, including the asymptotics for …

This paper is the first of a series regarding the Teukolsky equation of spin $\pm 1$ and spin
$\pm 2$ on Kerr backgrounds in the full subextremal range of parameters $| a|< M $. In the …

The excitation of quadratic quasinormal modes is an important nonlinear phenomenon for a
Kerr black hole ringing at a specific linear mode. The amplitude of this second-order effect is …

The last few years have seen considerable mathematical progress concerning the
asymptotic structure of gravitational radiation in dynamical, astrophysical spacetimes. In this …

We describe a class of wormholes that generically become traversable after incorporating
gravitational back-reaction from linear quantum fields satisfying appropriate (periodic or anti …

We prove that there are no exponentially growing modes nor modes on the real axis for the
Teukolsky equation on Kerr black hole spacetimes, both in the extremal and subextremal …
