"Multiwavelength Observations of A0620-00 in Quiescence." The Astrophysical Journal, 743, (1). https://doi.org/10.1088/0004-637X/743/1/26.
We present contemporaneous X-ray, ultraviolet, optical, near-infrared, and radio observations of the black hole binary system, A0620-00, acquired in 2010 March. Using the Cosmic Origins Spectrograph on the Hubble Space Telescope, we have obtained the first FUV spectrum of A0620-00 as well as NUV observations with the Space Telescope Imaging Spectrograph. The observed spectrum is flat in the FUV and very faint (with continuum fluxes sime 1e – 17 erg cm–2 s–1 Å–1). The UV spectra also show strong, broad (FWHM ~ 2000 km s–1) emission lines
