The paper titled “Study of the Origin of the Azimuthal Variation of Synchrotron X-ray Spectrum from SNR RX J0852.0-4622,” authored by Dr. Dai Tateishi from the Bamba lab, has been accepted for PASJ.
In this study, the authors compared the spatial distribution of the X-ray spectrum of SNR RX J0852.0-4622 with the distribution of molecular cloud density and shock velocity. The results indicate a positive correlation between molecular cloud density and X-ray flux throughout the SNR. Additionally, a positive correlation was found between X-ray flux and shock velocity in the southern region of the SNR.
Based on these findings, the authors conclude that the spatial distribution of the X-ray spectrum can be qualitatively explained by an increase in roll-off energy due to two factors: (A) the interaction between the shock wave and dense clouds in the northern part of the SNR, and (B) the high shock velocity in the southern region.
