SUMMARY:The Rise of the Leptons: Pulsar Emission Dominates the TeV Sky
 \, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Tim Linden\, CCAP\, Ohi
 o State University
DESCRIPTION:Recent HAWC observations have found extended TeV emission 
 coincident<br><br><br>
\nwith the Geminga and Monogem pulsars. In this
  talk\, I will show that<br><br><br>
\nthese detections have significa
 nt implications for our understanding<br><br><br>
\nof pulsar emission
 . First\, the spectrum and intensity of these TeV<br><br><br>
\nHalos 
 indicates that a large fraction of the pulsar spindown energy is<br><b
 r><br>
\nefficiently converted into electron-positron pairs. This prov
 ides<br><br><br>
\nobservational evidence supporting pulsar interpreta
 tions of the rising<br><br><br>
\npositron fraction observed by PAMELA
  and AMS-02. Second\, the isotropic<br><br><br>
\nnature of this emiss
 ion provides a new avenue for detecting nearby<br><br><br>
\npulsars w
 ith radio beams that are not oriented towards Earth. Lastly\,<br><br><
 br>
\nI will show that the total emission from all unresolved pulsars<
 br><br><br>
\nproduces the majority of the TeV gamma-ray flux observed
  from the<br><br><br>
\nMilky Way.
