HOT GASEOUS CORONAE IN THE DARK MATTER HALOS OF PRESENT DAY MASSIVE GALAXIES ARE THE FUNDAMENTAL PREDICTION OF GALAXY FORMATION MODELS. ALTHOUGH THE FIRST CORONAE AROUND MASSIVE SPIRALS HAVE RECENTLY BEEN DETECTED THESE DATA ONLY ALLOW US TO MEASURE THEIR BASIC PROPERTIES AND CARRY NOTABLE SYSTEMATIC UNCERTAINTIES. WE PROPOSE A DEEP XMM-NEWTON OBSERVATION OF NGC 6753. WE WILL (1) ESTABLISH THE TEMPERATURE AND METALLICITY STRUCTURE OF THE GAS (2) UTILIZE COMPLEX SPECTRAL MODELS THEREBY REMOVING THE SYSTEMATIC UNCERTAINTIES AND (3) CONSTRAIN THE BARYON MASS FRACTION. THUS WE WILL PLACE ROBUST CONSTRAINTS ON STATE-OF-THE-ART GALAXY FORMATION MODELS AND PROBE THE PHYSICAL PROCESSES THAT PLAY A CRUCIAL ROLE IN GALAXY EVOLUTION.
