TNG50 Infinite Galleries

These images follow Figure 2 of Ramesh+ (2023b), and visualize the gaseous halos surrounding Milky Way-like galaxies in TNG50, at redshift zero. These views of the circumgalactic medium (CGM) are shown on the scale of the virial radius of the parent dark matter halo (largest white circle). The white shapes show the actual location, and morphology, of large cold clouds identified in the CGM, while white circles show the locations and sizes of smaller cold clouds (with total masses less than 5x10⁵ M_sun). The background map shows the gas column density projection, and the yellow markers and lines show the positions of the three most massive satellites with baryon fraction at least 10%, if available, and their past orbits. Each galaxy in this sample of 132 is shown three times, from three different projection directions.
