Cosmological Simulations $256^3$ particles, 115 Mpc/h box.

Right: Cholla_PM

Updated: Now every pair of images has the same dynamical range for the colormap and all the images are density projections of the CIC mass interporlation into a 256^3 grid

## Case 1: ( Original one )

Gadget: $\epsilon \, = \,9.7 \,kpc/h$

Cholla: $cellSize \, = \, 449.2 \,kpc/h$

## Case 2:

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

Gadget: $\epsilon \, = \,449.2 \,kpc/h$

Cholla: $cellSize \, = \, 449.2 \,kpc/h$

## Case 3:

For this one the force grid of Cholla is $512^3$ and is compared to Gadget original high resolution one.

Gadget: $\epsilon \, = \,9.7 \,kpc/h$

Cholla: $cellSize \, = \, 224.6 \,kpc/h$
