Review of Boltzman equation based galaxy collisions

Plummer model used as an example

 

(1) Plummer model at rest and Monte Carlo (built on Assignment 3)

 

(2) Role of smeared gravitational potential in collisionless realization (like in Arseth code)

Aarseth's paper on the nbody code

 

(3) Embedding small Plummer sphere inside large Plummer sphere (mimicking the bulge inside the disk)

 

(4) Plummer model in uniform motion

 

(5) Plummer model in external gravitational field (CBE Monte Carlo)

 

(6) Two Plummer spheres colliding on elliptic orbits (CBE Monte Carlo)
