TeV Gamma-Ray Emission Observed from Geminga with HAWC

Understand

Geminga is a radio-quiet pulsar ~250 parsecs from Earth that was first discovered as a GeV gamma-ray source and then identified as a pulsar.

• Milagro observed an extended TeV source spatially consistent with Geminga.
• HAWC observes a similarly extended source.
• Observations of Geminga's flux and extension will be presented.
