Query: A Cosmic-ray Electron Spectrum with VERITAS   Cosmic-ray electrons and positrons (CREs) at GeV-TeV energies are a unique
probe of our local Galactic neighbourhood. CREs lose energy rapidly via inverse
Compton scattering and synchrotron processes while propagating in the Galaxy,
effectively placing a maximal propagation distance for TeV electrons of order
~1 kpc. Within this window, detected CREs can come from only a handful of
known, nearby astrophysical sources capable of exciting CREs to that energy or
from more exotic production mechanisms, like particle dark matter. HESS, and
later MAGIC, have shown that ground-based imaging atmospheric Cherenkov
telescopes have the capability to measure CREs into the TeV band. In this
proceedings we'll discuss the status of a VERITAS measurement of the electron
plus positron cosmic ray spectrum.
