Low-frequency oscillations in black holes: a spectral-timing approach to the case of GX 339-4
Low-frequency oscillations in black holes: a spectral-timing approach to the case of GX 339-4
We analyzed RXTE/PCA and HEXTE data of the transient black hole binary GX 339-4, col- lected over a time span of eight years. We studied the properties and the behavior of low frequency quasi periodic oscillations (QPOs) as a function of the integrated broad-band variability and the spectral parameters during …
