vrms

Hi Volker,

Halos from a 1 Mpc/h box size simulation stopped at z=0.25 have a systematically high vrms;
for example, the most massive halo at this time has a vrms(3d)= 83.1 km/s or so while
Vmax=40.6 km/s (where Vmax is the maximum circular velocity). I also run this simulation with
ART using the same ICs and found a lower vrms=47 km/s or so for the same halo. Density profiles,
on the other hand, look similar. Do you have any idea why I am getting these high values of vrms?

Cheers,

Pedro
