Investigating the Anticorrelation between Photon Index and Flux of the Crab Using RXTE and NuSTAR

The Astrophysical Journal
We present a systematic study of the recently reported anticorrelation between X-ray flux and photon index (Γ) in the Crab Nebula, using archival Rossi X-Ray Timing Explorer (RXTE) Proportional Counter Array (3–50 keV), RXTE High Energy X-ray Timing ...

The Crab Nebula Revisited Using HST/WFC3

The Astrophysical Journal
It has been over 24 years since the iconic Crab Nebula has been visited by the high spatial resolution eye of the Hubble Space Telescope (HST). The expanding nebula is dynamic on these timescales, with many of the outer filaments of the nebula known to ...

Flickers, Bursts, and Dips: Detecting Rapid Variability with the g(2) Autocorrelation Function

The Astrophysical Journal
Rapid optical transient events can be hard to detect because of the limited number of photons they produce. I discuss a method of inferring the presence of fast, chaotic variability in photometry using the normalized autocorrelation function, what is ...
