Investigating the Anti-Correlation between Photon Index and Flux of the Crab using RXTE and NuSTAR

Debjit Chatterjee, Hsiang-Kuang Chang, Dipak Debnath +2

We present a systematic study of the recently reported anti-correlation between X-ray flux and photon index ($\Gamma$) in the Crab Nebula, using archival RXTE/PCA (3 - 50 keV), RXTE/HEX…
