Abstract

A sustained, neutral wind from the outer accretion disk is observed in the transient black hole V404 Cygni during a violent outburst; this unusual wind, which expands at one per cent of the speed of light and triggers a nebular phase once accretion drops sharply and the ejecta become optically thin, probably regulates the outburst evolution of the black hole.
