We investigate what drives the redshift evolution of the typical electron density ($n_e$) in star-forming galaxies, using a sample of 140 galaxies drawn primarily from KMOS$^{\rm 3D}$ ($0. 6\lesssim{z}\lesssim{2. 6}$) and 471 galaxies from SAMI ($z<0. 113$).

VINE -- A numerical code for simulating astrophysical systems using particles II: Implementation and performance characteristics

no code implementations • 28 Feb 2008 • Andrew F. Nelson, M. Wetzstein, T. Naab, .

We continue with a detailed description of a number of optimizations made to the layout of the particle data in memory and to our implementation of a binary tree used to access that data for use in gravitational force calculations and searches for SPH neighbor particles.
