Likely detection of GeV γ-ray emission from pulsar wind nebula G32.64+0.53 with Fermi-LAT
Yifan Xiao, Keyao Wu, Jun Fang
In this study, we report the likely GeV γ-ray emissions originating from the pulsar PSR J1849-0001's pulsar wind nebula (PWN) G32.64+0.53. Our analysis covers approximately 14.7 ye…

Possible GeV gamma-ray emission from the pulsar wind nebula in CTA 1
Liancheng Zhou, Keyao Wu, Yunlu Gong +1
We report a detection of GeV -ray emission potentially originating from the pulsar wind nebula in CTA 1 by analyzing about 15 yr of Fermi Large Area Telescope data. By selecting…
