The Physics of the Nebular Phase in Black Hole X-ray Binaries: Modelling V404 Cygni
A. Ambrifi, T. Muñoz-Darias, J. A. Fernández-Ontiveros +3
Some of the most extreme galactic black hole transients exhibit a nebular phase at the end of their outbursts. This stage was first identified in the 2015 outburst of V404 Cygni, w…
Compact jets dominate the continuum emission in low-luminosity active galactic nuclei
J. A. Fernández-Ontiveros, X. López-López, A. Prieto
The disappearance of the accretion disc in low-luminosity active galactic nuclei (LLAGN) leaves behind a faint optical nuclear continuum whose nature has been largely debated, main…
X-ray binary accretion states in Active Galactic Nuclei? Sensing the accretion disc of supermassive black holes with mid-infrared nebular lines
Juan A. Fernández-Ontiveros, Teo Muñoz-Darias
Accretion states, which are universally observed in stellar-mass black holes in X-ray binaries, are also anticipated in active galactic nuclei (AGN). This is the case at low lumino…
Optical spectroscopy of 4U 1812-12: an ultra-compact X-ray binary seen through an H II region
M. Armas Padilla, T. Muñoz-Darias, F. Jiménez-Ibarra +6
The persistent, low-luminosity neutron star X-ray binary 4U 1812-12 is a potential member of the scarce family of ultra-compact systems. We performed deep photometric and spectrosc…
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)…
A connection between plasma conditions near black hole event horizons and outflow properties
K. I. I. Koljonen, D. M. Russell, J. A. Fernández Ontiveros +9
Accreting black holes are responsible for producing the fastest, most powerful outflows of matter in the Universe. The formation process of powerful jets close to black holes is po…
