X-ray spectral-timing variability of 1A 0535+262 during the 2020 giant outburst
X-ray spectral-timing variability of 1A 0535+262 during the 2020 giant outburst
The Be/X-ray binary 1A 0535+262 underwent a giant X-ray outburst in November 2020, peaking at $\sim1\times 10^{38}$ erg s$^{-1}$ (1--100 keV, 1.8 kpc), the brightest outburst recorded for this source so far. Our goal is to search for patterns of correlated spectral and timing behavior that can be used to …
