Abstract
Abstract A new γ-ray source with a significance level of approximately 5σ was reported in the region of the supernova remnant (SNR) G272.2–3.2 by analyzing the approximately 12.4 yr of observation data from the Fermi Large Area Telescope. Its γ-ray spatial distribution did not show an extended feature, and it had a soft spectrum with a spectral index of 2.56 ± 0.01 in the power-law model. No significant variability of its light curve with 10 time bins was identified, and its spatial positions in the X-ray and GeV bands overlapped. We suggest that the new γ-ray source is a likely counterpart of SNR G272.2–3.2. Analyzing its spectrum, we discussed the likely origins of the γ-ray emission.
