At the lower energies cosmic-ray secondary positrons dominate the flux, while at higher energies a new type of source becomes important. If that source is energetic local pulsars, they are expected to contribute to both the cosmic-ray positron and electron fluxes. This would result in features in their respective spectra that would coincide in energy; which we search for. We first fit the individual fluxes with parametrically smooth spectra to identify the significance of such features on either the electrons or the positrons and evaluate their respective residual fluxes. We then perform a cross-correlation analysis on the residual fluxes to see if their features are related and report our results.Cosmic raysCross-correlationPulsarsModelingThesis
