An Optically-Discovered Outburst from XTE J1859+226
Eric C. Bellm, Yuankun Wang, Jan van Roestel +13
Using the Zwicky Transient Facility, in 2021 February we identified the first known outburst of the Black Hole X-ray Transient XTE J1859+226 since its discovery in 1999. The outbur…
Investigating Non-linear and Stochastic Hard X-ray Variability of Active Galactic Nuclei using Recurrence Analysis
R. A. Phillipson, M. S. Vogeley, P. T. Boyd
We present results of recurrence analysis of 46 active galactic nuclei (AGN) using light curves from the 157-month catalog of the Swift Burst Alert Telescope (BAT) in the 14-150 ke…
Complex Variability of Kepler AGN Revealed by Recurrence Analysis
R. A. Phillipson, P. T. Boyd, A. P. Smale +1
The advent of new time domain surveys and the imminent increase in astronomical data expose the shortcomings in traditional time series analysis (such as power spectra analysis) in…
The Chaotic Long-term X-ray Variability of 4U 1705--44
Rebecca A. Phillipson, Patricia T. Boyd, Alan P. Smale
The low-mass X-ray binary 4U1705-44 exhibits dramatic long-term X-ray time variability with a timescale of several hundred days. The All-Sky Monitor (ASM) aboard the Rossi X-ray Ti…
