This research aims to explore the formation of galaxies and large structures through simulations of dark matter and baryon interactions.
Simulations modeling 2 gravitationally coupled fluids: dark matter and baryons with 10% baryon mass fraction.
Used a periodic 16 Mpc cube with 64^3 particles in each fluid and initial perturbations from a cold dark matter spectrum.
Analyzed baryon concentrations to identify galaxy-like objects that trace the dark matter filaments.
Simulated galaxies maintain identity in clusters, alleviating the overmerger problem with a lower merger rate of 2 relative to dark matter halos.
The inferred abundance of galaxies increases rapidly up to redshift z = 2, flattening thereafter.
A strong correlation between cold baryonic mass and maximum rotation velocity is identified, with M proportional to V_rot^2.5.
