When astrophysical jets were discovered one hundred years ago, the field of numerical
simulations did not yet exit. Since the arrival of programmable computers though, numerical …

There is a broad consensus that accretion onto supermassive black holes and consequent
jet formation power the observed emission from active galactic nuclei (AGNs). However …

Energy deposition by active galactic nuclei jets into the ambient medium can affect galaxy
formation and evolution, the cooling of gas flows at the centres of galaxy clusters, and the …

Aims. The collimation of relativistic jets in galaxies is a poorly understood process. Detailed
radio studies of the jet collimation region have been performed so far in a few individual …

Abstract The evolution of Fanaroff–Riley type I (FR I) jets has long been studied in the
framework of the FR I–FR II dichotomy. The present paradigm consists of the expansion of …

We present the HOLISMOKES programme on strong gravitational lensing of supernovae
(SNe) as a probe of SN physics and cosmology. We investigate the effects of microlensing …

An overview of grid-based numerical methods used in relativistic hydrodynamics (RHD) and
magnetohydrodynamics (RMHD) is presented. Special emphasis is put on a comprehensive …

Jets in low-luminosity radio galaxies are known to decelerate from relativistic speeds on
parsec scales to mildly or subrelativistic speeds on kiloparsec scales. Several mechanisms …

We present the results from an ultra-high-resolution 7 mm Very Long Baseline Array study of
the relativistic jet in the BL Lacertae object OJ287 from 1995 to 2011 containing 136 total …

Context. The winds from a non-accreting pulsar and a massive star in a binary system
collide forming a bow-shaped shock structure. The Coriolis force induced by orbital motion …
