Flux Variation of the Crab Pulsar Observed Using Fermi LAT and NuSTAR
Koothodil Abhijith Augustine, Hsiang-Kuang Chang
The flux of pulsed emission from the Crab pulsar, just like most of other pulsars, is considered to be steady over time scales much larger than the pulsation period, except for a s…
Predictions for Short Gamma-Ray Burst Detections by COSI
Eliza Neights, Eric Burns, Nicolò Parmiggiani +21
The Compton Spectrometer and Imager (COSI) is a soft gamma-ray telescope scheduled to launch in 2027. COSI will trigger onboard the spacecraft in response to short-duration transie…
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 () in the Crab Nebula, using archival RXTE/PCA (3 - 50 keV), RXTE/HEX…
Anti-correlation between Flux and Photon Index of Hard X-ray Emission from The Crab
Koothodil Abhijith Augustine, Hsiang-Kuang Chang
Using \textit{Swift} Burst Alert Telescope (BAT) event-mode data during Gamma Ray Burst (GRB) occurrences, we conducted spectral analysis for the Crab system. From 38 good observat…
