Detection of GeV $\gamma$-Ray Emission from supernova remnant SNR G15.9+0.2 with Fermi-LAT

Yunchuan Xiang, Zejun Jiang, Mengyao Tang

We first report GeV $\gamma$-ray emission from supernova remnant (SNR) G15.9+0.2 in this work. The results show that its power-law spectral index is 2.94$\pm$0.25 with a 6.47$\sigma$ signifi…
