SURPRISINGLY EXTENDED VERY-HIGH-ENERGY GAMMA-RAY EMISSION HAVE BEEN DETECTED AROUND SEVERAL MIDDLE-AGED PULSARS BY THE HAWC OBSERVATORY. THE NATURE OF THESE TEV HALOS IS UNKNOWN. WE HAVE SET UP A FRAMEWORK TO JOINTLY ANALYZE FERMI-LAT AND HAWC OBSERVATIONS OF A REGION-OF-INTEREST. WE WILL APPLY THIS FRAMEWORK TO THE SKY REGIONS WITH DETECTED TEV HALOS AROUND MIDDLE-AGED PULSARS. OUR METHOD ENABLES A SIMULTANEOUS FIT TO THE 100 MEV TO 100 TEV DATA AND CAN DIRECTLY ADDRESS THE QUESTION WHETHER GAMMA-RAY EMISSION OVER SIX DECADES IS PRODUCED BY A COMMON COSMIC-RAY POPULATION THAT ARE ORIGINATED FROM THE PULSARS AND DIFFUSE TO THE SURROUNDINGS. THIS PROJECT WILL ADVANCE THE UNDERSTANDING OF PARTICLE ACCELERATION AND INTERACTION IN THE VICINITY OF PULSARS.
