In between all the stars in our galaxy, there is a vast, diffuse mix of gas and dust known as the interstellar medium — and scientists have developed a new computer model to explore the magnetism and ...

Spin out: visualization of a general-relativistic collisionless plasma simulation shows the density of positrons near the event horizon of a rotating black hole. Plasma instabilities produce ...

A direct numerical simulation technique combined with a two-way coupling method was developed to study a gas-solid turbulent jet with a moderately high Reynolds number. The flow was weakly ...
