DXRBS' unique combination of a dual X-ray/radio survey method and high sensitivity has opened up important, large new regions of parameter space for both blazar sub-classes, within which a large fraction of our sample (nearly 50%) lie. This section is devoted to discussing these discoveries and their impact upon our understanding of the blazar class. љ . FSRQs . BL Lacs . Paolo Padovani . 1/5/1998

. A "radio phoenix" has been discovered using X-ray, radio, and optical data. This system contains the collision of two galaxy clusters located about 1.6 billion light years from Earth. The collision re-energized a regeneration of vast clouds of high-energy particles that primarily radiate at radio frequencies. Understanding how galaxy clusters grow over time, including through collisions, is important for cosmology. X-ray: NASA/CXC/Univ of Hamburg/F. de Gasperin et al; Optical: SDSS; Radio: NRAO/VLA
