Cosmological Simulations \(256^3\) particles, 115 Mpc/h box.

Cumulative Halo Mass Function

Solid lines correspond to the CHOLLA_PM simulation, red dashed lines correspond to the Gadget simulation and black dashed lines correspond to the model by Warren.

Case 1:

Gadget: \(\epsilon \, = \,9.7 \,kpc/h\)

Cholla: \(cellSize \, = \, 224.6 \,kpc/h\)

Case 2:

For this one the force resolution of Gadget was decreased to match the cell_size used for Cholla

Gadget: \(\epsilon \, = \,224.6 \,kpc/h\)

Cholla: \(cellSize \, = \, 224.6 \,kpc/h\)
