How to make galaxies with the wrong amount of dark matter

For nearly all large-scale objects, dark matter is a vital part of the story. <img alt="" src="https://miro.medium.com/v2/resize:fit:700/0*3m_-WkwW_Ufn3h1L" style="height:364px; width:700px" /> The cosmic web that we see, the largest-scale structure in the entire Universe, is dominated by dark matter. Simulations of the large-scale structure of the Universe must include both dark matter and normal matter, including the effects of star-formation, feedback, and gas infall, as all of them are needed in order to predict the emergence of visible structures. Identifying which regions are dense and massive enough to correspond to star clusters, galaxies, galaxy clusters, and filaments, as well as determining when and under which conditions they form, is one of the great achievements of modern cosmology. (<a href="https://news.fnal.gov/2020/04/the-milky-ways-satellites-help-reveal-link-between-dark-matter-halos-and-galaxy-formation/" rel="noopener ugc nofollow" target="_blank">Credit</a>: Ralf Kaehler/SLAC National Accelerator Laboratory) <a href="https://medium.com/starts-with-a-bang/how-to-make-galaxies-with-the-wrong-amount-of-dark-matter-f35f6ed6ca70">Click Here</a>
