PublicaciónUnveiling optical signatures of outflows in accreting white dwarfs
Accreting white dwarfs are known to show signatures of wind-type outflows in the ultraviolet. However, at optical wavelengths, wind detections have only been...

PublicaciónUnveiling recurrent jets of the ULX Holmberg II X-1: evidence for a massive stellar-mass black hole?
We report on the discovery of an apparent triple radio structure hidden inside the radio bubble of the ultraluminous X-ray source Holmberg II X-1. The...

PublicaciónV533 Herculis: the second SW Sex old nova displaying emission-line flaring
We present high-time-resolution spectroscopy of the non-eclipsing old nova V533 Herculis (N Her 1963). It is the second nova remnant affected by the `SW Sex...
