Detecting and characterizing pulsar haloes with the Cherenkov telescope array

The recently identified source class of pulsar haloes may be numerous and bright enough in the TeV range to constitute a large fraction sources that will observed with Cherenkov Telescope Array (CTA). In this work, we quantify prospects for detecting characterizing observations projected Galactic Plane Survey (GPS), using simple phenomenological diffusion model individual their population Milky Way. Our ability uncover constrain main physical parameters CTA GPS is assessed framework full spatial-spectral likelihood analysis simulated survey observations, most recent estimates instrument response function prototypes science tools. For setup representative halo around Geminga, find about three hundred objects could give rise detectable emission survey. Yet, only third them through energy-dependent morphology, one-tenth would allow derivation strong constraints on key like magnitude or extent suppressed pulsar. We also provide list known pulsars hosting (Geminga-like) assess robustness our findings against several systematic uncertainties.
