Predictions for the X-ray circumgalactic medium of edge-on discs and spheroids
Anna Nica, Benjamin D. Oppenheimer, Robert A. Crain +5
We investigate how the X-ray circumgalactic medium (CGM) of present-day galaxies depends on galaxy morphology and azimuthal angle using mock observations generated from the EAGLE c…
