Completing and Ensuring Major Impact from the XMM-SERVS Survey

WE PROPOSE TO COMPLETE OUR 12 DEG 2 SURVEY AT 50 KS DEPTH OF THREE LEGACY SKY REGIONS: THE SERVS AREAS OF W-CDF-S ELAIS-S1 AND XMM-LSS. XMM-LSS WON A 1.3 MS AO-15 ALLOCATION. W-CDF-S AND ELAIS-S1 COVERAGE IS NOW INTEGRALLY REQUIRED SO THAT XMM-SERVS CAN DRAMATICALLY ADVANCE STUDIES OF SMBH GROWTH ACROSS THE FULL RANGE OF COSMIC ENVIRONMENTS LINKS BETWEEN SMBH ACCRETION AND HOST-GALAXY PROPERTIES GROUPS/CLUSTERS AT Z = 0.1-2 PROTOCLUSTERS AND OTHER TOPICS. XMM-SERVS WILL ALLOW OUTSTANDING STUDIES OF THE NEWLY DETECTED 9000 AGNS AND 760 X-RAY GROUPS/CLUSTERS BY POWERFULLY LEVERAGING ITS SUPERIOR RADIO-TO-UV COVERAGE AND ITS FIELDS WILL HAVE EXTRAORDINARY LEGACY VALUE AS MOONS MASSIVE SPECTROSCOPY FIELDS DES/LSST DEEP-DRILLING FIELDS AND PRIME ALMA FIELDS.
