Revisiting the fundamental parameters for the black hole X-ray transient Swift J1753.5-0127
I. V. Yanes-Rizo, M. A. P. Torres, J. Casares +4
We present time-resolved Gran Telescopio Canarias optical spectroscopy and William Herschel Telescope -band photometry of the X-ray transient SWIFT J1753.5-0127 in quiescence. T…
State-dependent signatures of jets and winds in the optical and infrared spectrum of the black hole transient GX 3394
A. Ambrifi, D. Mata Sánchez, T. Muñoz-Darias +14
GX 3394 is one of the prototypical black hole X-ray transients, exhibiting recurrent outbursts that allow detailed studies of black hole accretion and ejection phenomena. In thi…
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…
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…
A correlation between Ha trough depth and inclination in quiescent X-ray transients: evidence for a low-mass black hole in GRO J0422+32
J. Casares, T. Muñoz-Darias, M. A. P. Torres +11
We present a new method to derive binary inclinations in quiescent black hole (BH) X-ray transients (XRTs), based on the depth of the trough (T) from double-peaked Ha emission prof…
Hard-state optical wind during the discovery outburst of the black-hole X-ray dipper MAXI J1803-298
D. Mata Sánchez, T. Muñoz-Darias, V. A. Cúneo +6
We present twelve epochs of optical spectroscopy taken across the discovery outburst of the black hole candidate MAXI J1803-298 with the GTC and VLT telescopes. The source followed…
Discovery of optical outflows and inflows in the black hole candidate GRS 1716-249
V. A. Cúneo, T. Muñoz-Darias, J. Sánchez-Sierras +12
We present optical spectroscopy obtained with the GTC, VLT and SALT telescopes during the decline of the 2016-2017 outburst of the black hole candidate GRS 1716-249 (Nova Oph 1993)…
The Changing-look Optical Wind of the Flaring X-ray Transient Swift J1858.6-0814
T. Muñoz-Darias, M. Armas Padilla, F. Jiménez-Ibarra +15
We present the discovery of an optical accretion disk wind in the X-ray transient Swift J1858.6-0814. Our 90-spectrum data set, taken with the 10.4m GTC telescope over 8 different…
Hard-state accretion disk winds from black holes: the revealing case of MAXI J1820+070
T. Muñoz-Darias, F. Jiménez-Ibarra, G. Panizo-Espinar +16
We report on a detailed optical spectroscopic follow-up of the black hole transient MAXI J1820+070 (ASASSN-18ey). The observations cover the main part of the X-ray binary outburst,…
Multi-wavelength spectroscopy of the black hole candidate MAXI J1813-095 during its discovery outburst
M. Armas Padilla, T. Muñoz-Darias, J. Sánchez-Sierras +5
MAXI J1813-095 is an X-ray transient discovered during an outburst in 2018. We report on X-ray and optical observations obtained during this event, which indicate that the source i…
