How to Make Genetically Engineered Halos in Cosmological Simulations
Today’s guest post takes a look at a technique that cleverly tweaks simulated galaxy halos very early on in their lives in order to direct their growth in a specific way

How big is a galaxy cluster? Today’s authors use the remnants of destroyed galaxies to define the edge of galaxy clusters.
What processes can explain the diversity in star formation rates exhibited by galaxies of similar masses? Today’s authors investigate this using the EAGLE simulation.
Thanks to the Gaia satellite and other incredible data sources, we are in for a set of unprecedented discoveries about our galaxy over the next few years. Learn more about them at Dr. Adrian Price-Whelan’s talk at #AAS237!
When we observe galaxies and measure their dark matter halos, we exclude subhaloes from the halo’s mass profile. When we simulate haloes, we include them. But what if we didn’t?
How well a galaxy dances may be a matter of life or death.
