Searching for evidence of TeV-scale electron/positron acceleration by Millisecond Pulsars

Pulsars have long been predicted to be sources of electron/positron (e-e+) pairs. Highly energetic e-e+ in the wind regions, or inner magnetospheres of pulsars, and also when released into the interstellar medium, can inverse-Compton IC) scatter ambient photons to very high energies. Recent HAWC observations of extended TeV-scale gamma-ray emission around Geminga and Monogem have provided indirect evidence for multi-TeV e-e+ acceleration in young pulsar nebulae. However, predicting and observing very-high-energy gamma-ray emission from rotation-powered millisecond pulsars (MSPs) presents a number of challenges compared to that of the non-recycled pulsar population. During this talk, I will summarize these challenges, and present our recent exciting results where we find evidence for very-high-energy gamma ray emission from populations of MSPs residing in globular clusters of the Milky Way. I will further highlight the unique capabilities of the Cherenkov Telescope Array to detect the expected IC signal from a putative population of 10 to 50 thousand MSPs in the center of our Galaxy.
