The MillenniumTNG Project: The large-scale clustering of galaxies

Understand

Modern redshift surveys are tasked with mapping out the galaxy distribution over enormous distance scales.

• Existing hydrodynamical simulations, however, do not reach the volumes needed to match upcoming surveys.
• We present results for the clustering of galaxies using a new, large volume hydrodynamical simulation as part of the MillenniumTNG (MTNG) project.
• With a computational volume that is $\approx15$ times larger than the next largest such simulation currently available, we show that MTNG is able to accurately reproduce the observed clustering of galaxies as a function of stellar mass.
