We present a new, open source, free, semi-analytic model (SAM) of galaxy formation, Shark,
designed to be highly flexible and modular, allowing easy exploration of different physical …

The radiative efficiency of active galactic nucleus (AGN) is commonly estimated based on
the total mass accreted and the total AGN light emitted per unit volume in the universe …

Future space-based gravitational-wave detectors, such as the Laser Interferometer Space
Antenna (LISA/SGO) or a similar European mission (eLISA/NGO), will measure the masses …

We present the results of a semianalytical model that evolves the masses and spins of
massive black holes together with the properties of their host galaxies across the cosmic …

We track the coevolution of supermassive black holes (SMBHs) and their host galaxies
through cosmic time. The calculation is embedded in the galform semi-analytic model which …

Supermassive black holes (BHs) at the centres of galaxies can rapidly change their mass
and spin by gas accretion and mergers. Using hydrodynamical cosmological simulations …

ABSTRACT BL Lac objects are the best candidates to study the jet properties since their
spectral energy distributions (SEDs) are less contaminated by the emission from the …

Massive black holes (MBHs), in contrast to stellar mass black holes, are expected to
substantially change their properties over their lifetime. MBH masses increase by several …

The environs of supermassive black holes are among the universe's most extreme
phenomena. Understanding the physical processes occurring in the vicinity of black holes …

We present the new semi-analytic model of galaxy evolution, Dark Sage, a heavily modified
version of the publicly available sage code. The model is designed for detailed evolution of …
