When the primary star in a close binary system evolves into a giant and engulfs its
companion, its core and the companion temporarily orbit each other inside a common …

We review theories of dark matter (DM) beyond the collisionless paradigm, known as self-
interacting dark matter (SIDM), and their observable implications for astrophysical structure …

We have generated synthetic images of∼ 27 000 galaxies from the IllustrisTNG and the
original Illustris hydrodynamic cosmological simulations, designed to match Pan-STARRS …

Abstract Smoothed Particle Hydrodynamics (SPH) is a relatively new meshless numerical
approach which has attracted significant attention in the last two decades. Compared with …

The primary source of emission of active galactic nuclei (AGNs), the accretion disc, is
surrounded by an optically and geometrically thick dusty structure ('the so-called dusty …

We use cosmological simulations to study the effects of self-interacting dark matter (SIDM)
on the density profiles and substructure counts of dark-matter haloes from the scales of …

Fluid-structure interaction (FSI) is a class of mechanics-related problems with mutual
dependence between the fluid and structure parts and it is observable nearly everywhere, in …

Smoothed particle hydrodynamics (SPH) is a meshfree particle method based on
Lagrangian formulation, and has been widely applied to different areas in engineering and …

The numerical convergence of smoothed particle hydrodynamics (SPH) can be severely
restricted by random force errors induced by particle disorder, especially in shear flows …

We discuss the cosmological simulation code gadget-2, a new massively parallel TreeSPH
code, capable of following a collisionless fluid with the N-body method, and an ideal gas by …
