Unveiling hidden variability components in accreting X-ray binaries using both the Fourier power and cross spectra
Mariano Mendez, Valentina Peirano, Federico Garcia +3
We present a novel method for measuring the lags of (weak) variability components in neutron-star and black-hole low-mass X-ray binaries (LMXBs). For this we assume that the power…
Dual-Corona Comptonization model for the Type-B Quasi-Periodic Oscillations in GX 339-4
Valentina Peirano, Mariano Méndez, Federico García +1
Characterising the fast variability in black-hole low-mass X-ray binaries (BHXBs) can help us understand the geometrical and physical nature of the innermost regions of these sourc…
Variability and phase lags of the type-C quasi-periodic oscillation of MAXI J1348-630 with NICER
Kevin Alabarta, Mariano Méndez, Federico García +4
We study the properties of the type-C quasi-periodic oscillation (type-C QPO) of MAXI J1348-630 during its 2019 outburst and reflare with NICER. This is the first time that the evo…
Lags of the KiloHertz Quasi-Periodic Oscillations in the transient source XTE J1701462
Valentina Peirano, Mariano Méndez
We analysed 14 observations with kilohertz quasi-periodic oscillations (kHz QPOs) of the neutron star X-ray binary XTE J1701462, the first source to show a clear transition betw…
Kilohertz quasi-periodic oscillations in neutron-star X-ray binaries: Flattening of the lag spectrum with increasing luminosity
Valentina Peirano, Mariano Méndez
We study the energy-dependent time lags and rms fractional amplitude of the kilohertz quasi-periodic oscillations (kHz QPOs) of a group of neutron-star low mass X-ray binaries (LMX…
