Low-frequency quasiperiodic oscillations (LFQPOs) are commonly found in black hole X-ray
binaries, and their origin is still under debate. The properties of LFQPOs at high energies …

Black holes in binary systems execute patterns of outburst activity where two characteristic X-
ray states are associated with different behaviours observed at radio wavelengths. The hard …

We extend our recent work on black hole spin in X-ray binary systems to include an analysis
of 189 archival NuSTAR observations from 24 sources. Using self-consistent data reduction …

We perform the first systematic search of all NICER archival observations of black hole (and
candidate) low-mass X-ray binaries for signatures of reverberation. Reverberation lags …

We report new radio observations of a sample of 36 neutron star (NS) X-ray binaries, more
than doubling the sample in the literature observed at current-day sensitivities. These …

We present the radio and X-ray monitoring campaign of the 2019/2020 outburst of MAXI
J1348–630, a new black hole X-ray binary (BH XRB) discovered in 2019 January. We …

We present a detailed spectral and temporal analysis of the black hole candidate MAXI
J1535− 571 using NICER observations in 2017 September and October. We focus …

Type-C quasi-periodic oscillations (QPOs) in black hole X-ray transients can appear when
the source is in the low-hard and hard-intermediate states. The spectral-timing evolution of …

Black hole (BH) accretion is one of nature's most efficient energy extraction processes.
When gas falls in, a significant fraction of its gravitational binding energy is either converted …

Characterizing the fast variability in black hole low-mass X-ray binaries (BHXBs) can help us
to understand the geometrical and physical nature of the innermost regions of these …
