The nuclei of most normal galaxies contain supermassive black holes, which can accrete
gas through a disk and become active. These active galactic nuclei (AGNs) can form jets that …

Mergers of binary neutron stars and black hole–neutron star binaries are among the most
promising sources for ground-based gravitational-wave (GW) detectors and are also high …

Abstract Event Horizon Telescope (EHT) observations at 230 GHz have now imaged
polarized emission around the supermassive black hole in M87 on event-horizon scales …

The nearby radio galaxy M87 offers a unique opportunity to explore the connections
between the central supermassive black hole and relativistic jets. Previous studies of the …

Abstract The Event Horizon Telescope (EHT) has mapped the central compact radio source
of the elliptical galaxy M87 at 1.3 mm with unprecedented angular resolution. Here we …

Event Horizon Telescope (EHT) observations at 230 GHz have now imaged polarized
emission around the supermassive black hole in M87 on event-horizon scales. This …

We present the results of nine simulations of radiatively inefficient magnetically arrested
discs (MADs) across different values of the black hole spin parameter a*:− 0.9,− 0.7,− 0.5 …

The central radio source in M87 provides the best opportunity to study jet formation because
it has a large angular size for the gravitational radius of the black hole and has a bright jet …

Gas falling into a black hole (BH) from large distances is unaware of BH spin direction, and
misalignment between the accretion disc and BH spin is expected to be common. However …

We describe global, 3D, time‐dependent, non‐radiative, general‐relativistic,
magnetohydrodynamic simulations of accreting black holes (BHs). The simulations are …
