Energy-Dependent Morphology of HAWCJ2019+368, an Energic Pulsar in the Dragonfly Nebula*

Inside the Dragonfly nebula is the pulsar PSR J2021+3651, one of the brightest sources of TeV gamma rays. Data from the High Altitude Water Cherenkov (HAWC) observatory has resolved the MGRO J2019+37 region, where the pulsar and nebula are located, into two sources: HAWC J2019+368 and HAWC J2016+371. The study of this source’s energy dependent morphology is indicative of the underling particles causing this gamma ray emission. Energy dependent morphology indicates that the size of the source is limited by energy lost in the particles producing gamma-rays. Using an expanded dataset from HAWC, we will search for energy dependent morphology. Measuring this energy dependent morphology will confirm the interpretation of HAWC J2019+368 as a TeV Pulsar Wind Nebula (PWN).
