Maps of continuum emission of the VY CMa dusty envelope. Left: maps of emission imaged with ALMA Bands 6 (top) and 7 (bottom) at Briggs weighting (robust 0.5). Middle: corresponding data imaged with a UV taper, which reduced the resolution to a FWHM of 450 mas. Top right: HST image at 1 μm smoothed to the angular resolution of ALMA Band 7 observations. Bottom right: map generated from combined visibilities of ALMA and SMA. The corresponding spatial resolution (FWHM) of each map is shown with a green ellipse in the lower left corners. Left panels: we additionally show the size of the largest angular scales. White contours are drawn at the respective 5σ levels. Black contours are shown at 3 levels spaced linearly from the peak to zero intensity (excluding zero).
