Abstract This review describes observations of hot coronae around early-type galaxies. The observations show that early-type galaxies have 0.5–4.5 keV luminosities up to nearly 1043 ergs sec−1 dominated by thermal emission from 1010 M⊚ of hot (∼ 107K) gas. We describe calculations which model the evolution of the coronae. These models can explain the present epoch observations as well as predict the coronal properties at large redshift.
