Multi-wavelength observations of NGC 4593. Left: Background merged image from Hubble Space Telescope (HST) observations, combining data from the Wide Field Planetary Camera 2 (WFPC2) using the F606W filter and the F547M filter. The squared zoomed region highlights the inner galaxy, showing the AGN at its centre. Middle: Zoomed region of the HST image with contours from the ALMA CO (J = 2 − 1) emission line moment-0 map, illustrating the distribution and intensity of CO emission with contour levels of Contours = [0.25, 0.35, 0.4, 0.5, 1, 2, 4, 6]. Right: Digitized Sky Survey (DSS) image of the galaxy (Image credit: DSS, STScI).
