 X-ray observations provide a powerful view of some of the most extreme processes in the Universe, and have had a 
-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

 entropy in hundreds of clusters, dramatically increasing understanding of cooling and heating processes in their 
 cores; quasi-periodic eruptions (QPE) from active galactic nuclei (AGN) were discovered [@qpedisco]; the high-energy 
 view of young stars gave insights into their magnetic fields and stellar winds [@coup; @xest]; calibrating
