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…
Evidence for a dynamic corona in the short-term time lags of black hole X-ray binary MAXI J1820+070
Niek Bollemeijer, Phil Uttley, Arkadip Basak +19
In X-ray observations of hard state black hole X-ray binaries, rapid variations in accretion disc and coronal power-law emission are correlated and show Fourier-frequency-dependent…
The omnipresent flux-dependent optical dips of the black hole transient Swift J1357.2-0933
G. Panizo-Espinar, T. Muñoz-Darias, M. Armas Padilla +15
Swift J1357.2-0933 is a black hole transient of particular interest due to the optical, recurrent dips found during its first two outbursts (in 2011 and 2017), with no obvious X-ra…
Shedding far-ultraviolet light on the donor star and evolutionary state of the neutron-star LMXB Swift J1858.6-0814
N. Castro Segura, C. Knigge, J. H. Matthews +13
The evolution of accreting X-ray binary systems is closely coupled to the properties of their donor stars. As a result, we can constrain the evolutionary track a system is by estab…
Clockwise evolution in the hardness-intensity diagram of the black hole X-ray binary Swift J1910.2-0546
Payaswini Saikia, David M. Russell, Saarah F. Pirbhoy +5
We present a detailed study of optical data from the 2012 outburst of the candidate black hole X-ray binary Swift J1910.2-0546 using the Faulkes Telescope and Las Cumbres Observato…
Matter ejections behind the highs and lows of the transitional millisecond pulsar PSR J1023+0038
M. C. Baglio, F. Coti Zelati, S. Campana +23
Transitional millisecond pulsars are an emerging class of sources that link low-mass X-ray binaries to millisecond radio pulsars in binary systems. These pulsars alternate between…
Seven reflares, a mini-outburst and an outburst : High amplitude optical variations in the black hole X-ray binary Swift J1910.2-0546
Payaswini Saikia, David M. Russell, Saarah F. Pirbhoy +5
We present long-term (2012-2022) optical monitoring of the candidate black hole X-ray binary Swift J1910.2-0546 with the Faulkes Telescopes and Las Cumbres Observatory (LCO) networ…
A NICER look at the jet-like corona of MAXI J1535-571 through type-B quasi-periodic oscillations
Yuexin Zhang, Mariano Méndez, Federico García +7
MAXI J1535-571 is a black-hole X-ray binary that in 2017 exhibited a very bright outburst which reached a peak flux of up to 5 Crab in the 2-20 keV band. Given the high flux, sever…
The comptonizing medium of the black-hole X-ray binary MAXI~J1535571 through type-C quasi-periodic oscillations
Divya Rawat, Mariano Méndez, Federico García +7
We present a detailed spectral and temporal analysis of the black-hole candidate MAXI~J1535571 using NICER observations in September and October 2017. We focus specifically on o…
