Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

Massive black holes (MBHs) inhabit galactic centres, and power luminous quasars and
active galactic nuclei, shaping their cosmic environment with the energy they produce. The …

We review recent works on the dynamics of circumbinary accretion, including time variability,
angular momentum transfer between the disk and the binary, and the secular evolution of …

We introduce the simba simulations, the next generation of the mufasa cosmological galaxy
formation simulations run with gizmo's meshless finite mass hydrodynamics. simba includes …

The existence of∼ 109M⊙ supermassive black holes (SMBHs) within the first billion years
of the Universe has stimulated numerous ideas for the prompt formation and rapid growth of …

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 …

We present the to-date largest parameter space exploration of binaries in circumbinary discs
(CBDs), deriving orbital evolution prescriptions for eccentric, unequal mass binaries from our …

Even if massive (10 M⊙≲ M≲ 10 4 M⊙) primordial black holes (PBHs) can only account for
a small fraction of the dark matter (DM) in the universe, they may still be responsible for a …

Active galactic nuclei (AGN) are powered by the accretion of material onto a supermassive
black hole (SMBH) and are among the most luminous objects in the Universe. However, the …

It is twenty years since the seminal works by Magorrian and co-authors and by Silk and
Rees, which, along with other related work, ignited an explosion of publications connecting …
