The Physical Nature of Circumgalactic Medium Absorbers in Simba
We study the nature of the low-redshift CGM in the Simba cosmological simulations as traced by ultraviolet absorption lines around galaxies in bins of stellar mass (M⋆>1010M⊙) for star-forming, green valley and quenched galaxies at impact parameters r⊥≤1.25r200. We generate synthetic spectra for HI, MgII, CII, SiIII, CIV, and OVI, fit Voigt profiles to obtain line …
