Wavelet analysis: a new significance test for signals dominated by intrinsic red-noise variability
Pawel Lachowicz
We develop a new statistical test for the wavelet power spectrum. We design it with purpose of testing signals which intrinsic variability displays in a Fourier domain a red-noise…
Wavelet analysis of MCG-6-30-15 and NGC 4051: a possible discovery of QPOs in 2:1 and 3:2 resonance
Pawel Lachowicz, Bozena Czerny, Marek A. Abramowicz
Following our previous work of Lachowicz & Czerny (2005), we explore further the application of the continuous wavelet transform to X-ray astronomical signals. Using the public arc…
Periodic long-term X-ray and radio variability of Cygnus X-1
Pawel Lachowicz, Andrzej A. Zdziarski, Alex Schwarzenberg-Czerny +2
We present a comprehensive analysis of long-term periodic variability of Cyg X-1 using the method of multiharmonic analysis of variance (mhAoV) applied to available monitoring data…
Wavelet analysis of millisecond variability of Cygnus X-1 during its failed state transition
Pawel Lachowicz, Bozena Czerny
Application of multi-resolution analysis adopting wavelets in order to investigate millisecond aperiodic X-ray variability of Cyg X-1 is presented. This relatively new approach in…
