The next two decades are expected to open the door to the first coincident detections of
electromagnetic (EM) and gravitational-wave (GW) signatures associated with massive …

Abstract The Event Horizon Telescope (EHT) Collaboration recently published the first
images of the supermassive black holes in the cores of the Messier 87 and Milky Way …

We present fully relativistic predictions for the electromagnetic emission produced by
accretion disks surrounding spinning and nonspinning supermassive binary black holes on …

The self-lensing of a massive black hole binary (MBHB), which occurs when the two BHs are
aligned close to the line of sight, is expected to produce periodic, short-duration flares. Here …

We perform a full 3D general relativistic magnetohydrodynamical (GRMHD) simulation of an
equal-mass, spinning, binary black hole approaching merger, surrounded by a circumbinary …

After the companion dynamically plunges through the primary's envelope, the two cores
remain surrounded by a common envelope and the decrease of the orbital period P orb …

Accreting supermassive binary black holes (SMBBHs) are potential multimessenger sources
because they emit both gravitational-wave and electromagnetic (EM) radiation. Past work …

We present an overview of recent numerical advances in the theoretical characterization of
massive binary black hole (MBBH) mergers in astrophysical environments. These systems …

If the envelope of a massive star is not entirely removed during common envelope (CE)
interaction with an orbiting compact (eg, black hole (BH) or neutron star (NS)) companion …

Accreting binary black holes (BBHs) are multimessenger sources, emitting copious
electromagnetic (EM) and gravitational waves. One of their most promising EM signatures is …
