Bayesian Blocks in Two or More Dimensions: Image Segmentation and Cluster Analysis
Jeffrey D. Scargle
This paper describes an extension, to higher dimensions, of the Bayesian Blocks algorithm for estimating signals in noisy time series data (Scargle 1998, 2000). The mathematical pr…
Bayesian Estimation of Time Series Lags and Structure
Jeffrey D. Scargle
This paper derives practical algorithms, based on Bayesian inference methods, for several data analysis problems common in time series analysis of astronomical and other data. One…
USA Observation of Spectral and Timing Evolution During the 2000 Outburst of XTE J1550-564
K. T. Reilly, E. D. Bloom, W. Focke +14
We report on timing and spectral observations of the 2000 outburst of XTE J1550-564 made by the Unconventional Stellar Aspect (USA) Experiment on board the Advanced Research and Gl…
Short Gamma-Ray Bursts Are Different
J. P. Norris, J. D. Scargle, J. T. Bonnell
We analyze BATSE time-tagged event (TTE) data for short gamma-ray bursts (T90 duration < 2.6 s), studying spectral lag vs. peak flux and duration, as well as the number of distinct…
Time-Evolution of the Power Spectrum of the Black Hole X-ray Nova XTE J1550-564
Lorenzo Galleani, Leon Cohen, Douglas Nelson +1
We have studied the time evolution of the power spectrum of XTE J1550-564, using X-ray luminosity time series data obtained by the Rossi X-Ray Timing Explorer satellite. A number o…
