Fast infrared winds during the radio-loud and X-ray obscured stages of the black hole transient GRS 1915+105
J. Sánchez-Sierras, T. Muñoz-Darias, S. E. Motta +10
The black hole transient GRS 1915+105 entered a new phase of activity in 2018, generally characterised by low X-ray and radio fluxes. This phase has been only interrupted by episod…
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…
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…
Dynamical mass of the white dwarf in XY Ari: a test for intermediate polar X-ray spectral models
A. Álvarez-Hernández, M. A. P. Torres, P. Rodríguez-Gil +7
We present a dynamical study of the eclipsing intermediate polar XY Ari based on time-resolved near-infrared spectroscopy obtained with the EMIR spectrograph on the 10.4-m Gran Tel…
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…
Discovery of optical and infrared accretion disc wind signatures in the black hole candidate MAXI J1348-630
G. Panizo-Espinar, M. Armas Padilla, T. Muñoz-Darias +11
MAXI J1348-630 is a low mass X-ray binary discovered in 2019 during a bright outburst. During this event, the system sampled both hard and soft states following the standard evolut…
Near-infrared emission lines trace the state-independent accretion disc wind of the black hole transient MAXI J1820+070
Javier Sánchez-Sierras, Teo Muñoz-Darias
The black hole transient MAXI J1820+070 displayed optical P-Cyg profiles and other wind-related emission line features during the hard state of its discovery outburst. We present n…
