The strength of Type-C quasi-periodic oscillations in black hole X-ray binaries correlates with the jet inclination
F. M. Vincentelli, N. Bollemeijer, A. Veledina +10
X-ray quasi-periodic oscillations (QPOs) are a characteristic feature of low-mass X-ray binaries (LMXBs). These oscillations have been studied for decades and revealed a rich and c…
Geometry of the comptonization region of MAXI J1348630 through type-C quasi-periodic oscillations with NICER
Kevin Alabarta, Mariano Méndez, Federico García +5
We use the rms and lag spectra of the type-C quasi-periodic oscillation (QPO) to study the properties of the Comptonisation region (aka corona) during the low/hard and hard-interme…
Unraveling the hybrid origins of the X-ray non-thermal emission from IGR J17091-3624
Zikun Lin, Yanan Wang, Santiago del Palacio +8
We present a comprehensive study based on multi-wavelength observations from the NuSTAR, NICER, Swift, Fermi, NEOWISE, and ATCA telescopes during the 2022 outburst of the black hol…
Dramatic Drop in the X-Ray Polarization of Swift J1727.81613 in the Soft Spectral State
Jiří Svoboda, Michal Dovčiak, James F. Steiner +34
Black-hole X-ray binaries exhibit different spectral and timing properties in different accretion states. The X-ray outburst of a recently discovered and extraordinarily bright sou…
A systematic study of the high-frequency bump in the black-hole low-mass X-ray binary GX 339-4
Yuexin Zhang, Mariano Méndez, Sara E. Motta +8
The high-frequency bump, characterized by a frequency exceeding ~30 Hz, represents a seldom-explored time-variability feature in the power density spectrum (PDS) of black-hole X-ra…
Type-A quasi-periodic oscillation in the black hole transient MAXI J1348-630
Liang Zhang, Mariano Méndez, Federico García +12
We present a detailed analysis of the spectral and timing characteristics of a 7-Hz type-A quasi-periodic oscillation (QPO) detected in NICER observations of the black hole X-ray b…
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…
