Abstract (from CDS):

Observations of the black hole X-ray binary V404 Cyg with the very long baseline interferometer the High Sensitivity Array (HSA) have detected the source at a frequency of 8.4GHz, providing a source position accurate to 0.3mas relative to the calibrator source. The observations put an upper limit of 1.3mas on the source size (5.2au at 4kpc) and a lower limit of 7 x106 K on its brightness temperature during the normal quiescent state, implying that the radio emission must be non-thermal, most probably synchrotron radiation, possibly from a jet. The radio light curves show a short flare, with a rise time of ∼30min, confirming that the source remains active in the quiescent state.
