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…
An infrared FWHM- correlation to uncover highly reddened quiescent black holes
V. A. Cúneo, J. Casares, M. Armas Padilla +7
Among the sample of Galactic transient X-ray binaries (SXTs) discovered to date, about 70 have been proposed as likely candidates to host a black hole. Yet, only 19 have been dynam…
Unveiling optical signatures of outflows in accreting white dwarfs
V. A. Cúneo, T. Muñoz-Darias, F. Jiménez-Ibarra +8
Accreting white dwarfs are known to show signatures of wind-type outflows in the ultraviolet. At optical wavelengths, however, wind detections have only been reported for a few sou…
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…
Sub-second infrared variability from the archetypal accreting neutron star 4U~1728-34
F. M. Vincentelli, P. Casella, A. Borghese +23
We report on the first simultaneous high-time resolution X-ray and infrared (IR) observations of a neutron star low mass X-ray binary in its hard state. We performed h…
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…
Multiwavelength observations of the extraordinary accretion event AT2021lwx
P. Wiseman, Y. Wang, S. Hönig +43
We present observations from X-ray to mid-infrared wavelengths of the most energetic non-quasar transient ever observed, AT2021lwx. Our data show a single optical brightening by a…
Optical and near-infrared spectroscopy of the black hole transient 4U 1543-47 during its 2021 ultra-luminous state
J. Sánchez-Sierras, T. Muñoz-Darias, J. Casares +10
We present simultaneous optical and near-infrared spectra obtained during the 2021 outburst of the black hole transient 4U 1543-47. The X-ray hardness-intensity diagram and the com…
A shared accretion instability for black holes and neutron stars
F. M. Vincentelli, J. Neilsen, A. J. Tetarenko +20
Accretion disks around compact objects are expected to enter an unstable phase at high luminosity. One instability may occur when the radiation pressure generated by accretion modi…
The evolution of the UV/optical lag spectrum of NGC 7469 seen by the Liverpool Telescope
F. M. Vincentelli, M. Beard, I. Mc Hardy +3
We present the results regarding the analysis of an intensive monitoring of the Active Galactic Nucleus (AGN) NGC 7469. We observed the source for 4 months with almost daily cadenc…
