+profound impact on our understanding of many types of astrophysical objects. Every sub-field of astronomy, astrophysics, and cosmology has benefited significantly from X-ray coverage over 
 the last three decades; the observation of X-ray cavities in galaxy clusters caused by central AGN helped to shed light 
 on the cooling-flow problem [@cavities]; further X-ray observations allowed for the measurement of spatially-resolved 
 entropy in hundreds of clusters, dramatically increasing understanding of cooling and heating processes in their
