Misalignment of angular momentum of stars (simulation)

Click For Summary
SUMMARY

The discussion centers on the analysis of angular momentum misalignment in a specific halo from an n-body simulation conducted using the RAMSES code, with halos identified by the AMIGA halo finder. The simulation spans redshift 99 to 2, focusing on the specific angular momentum of star content at a galaxy radius of 0.1 Rvir compared to dark matter/stars at various radii up to the virial radius. The user seeks insights into the implications of the calculated misalignment angles, particularly regarding intrinsic effects that may impact the simulation results, excluding gravitational lensing considerations.

PREREQUISITES
  • Familiarity with n-body simulations, specifically using RAMSES code.
  • Understanding of halo finding techniques, particularly the AMIGA halo finder.
  • Knowledge of angular momentum concepts in astrophysics.
  • Experience with cosmological redshift and its implications on galaxy formation.
NEXT STEPS
  • Investigate the implications of angular momentum misalignment in galaxy formation.
  • Explore the effects of dark matter distribution on galaxy dynamics.
  • Learn about the role of angular momentum in gravitational interactions and stability.
  • Research methods to quantify intrinsic effects in n-body simulations.
USEFUL FOR

Astronomers, astrophysicists, and researchers involved in galaxy formation studies, particularly those analyzing n-body simulations and angular momentum dynamics.

hey all! I have just finished processing the data of an n-body simulation (RAMSES code was used to do the simulation and AMIGA halo finder found our halos) ,so I have chosen a specific halo and it contains a massive galaxy (and of course satellite galaxies around it) and the code was run from redshift 99 to 2 and now I have calculated the misalignment between the specific angular momentum of star content of this simulation at galaxy radius (0.1 Rvir) and specific angular momentum of dark matter/stars for each radius up to virial radius. and also the angle (misalignment) between the total specific angular momentum of dark matter at virial radius and the specific angular momentum of dark matter/stars at each radius. I was just wondering if anyone knew what these angles could mean. I already know the effect on gravitational lensing, but I'm not interested in that. maybe something more intrinsic,something that could cause problems in the results! help me! :D many thanks!
