Modeling galaxy formation in a cosmological context presents one of the greatest
challenges in astrophysics today due to the vast range of scales and numerous physical …

I review current efforts to measure the mean density of dark matter near the Sun. This
encodes valuable dynamical information about our Galaxy and is also of great importance …

Including covariant information, such as position, force, velocity or spin is important in many
tasks in computational physics and chemistry. We introduce Steerable E (3) Equivariant …

To gain understanding of the complicated, non-linear, and numerical processes associated
with the tidal evolution of dark matter subhaloes in numerical simulation, we perform a large …

We report on the successful completion of a 2 trillion particle cosmological simulation to z= 0
z=0 run on the Piz Daint supercomputer (CSCS, Switzerland), using 4000+ GPU nodes for a …

We fit the rotation curves of isolated dwarf galaxies to directly measure the stellar mass–halo
mass relation (M⋆–M 200) over the mass range 5× 105≲ M⋆/M⊙≲ 108. By accounting for …

We perform numerical simulations of the merging galaxy cluster 1E 0657-56 (the Bullet
Cluster), including the effects of elastic dark matter scattering. In a similar manner to the …

We review the field of collisionless numerical simulations for the large-scale structure of the
Universe. We start by providing the main set of equations solved by these simulations and …

We present Phantom, a fast, parallel, modular, and low-memory smoothed particle
hydrodynamics and magnetohydrodynamics code developed over the last decade for …

The development of methods and algorithms to solve the N-body problem for classical,
collisionless, non-relativistic particles has made it possible to follow the growth and …
