X-ray metal line emission from the hot circumgalactic medium: probing the effects of supermassive black hole feedback

We derive predictions from state-of-the-art cosmological galaxy simulations for the spatial distribution of the hot circumgalactic medium (CGM, {\rm [0.1-1]R_{200c}}) through its emission lines in the X-ray soft band ([0.3-1.3] keV). In particular, we compare IllustrisTNG, EAGLE, and SIMBA and focus on galaxies with stellar mass 10^{10-11.6}\, \MSUN at z=0.... Show more
