Simulated maps of the foreground components and the 21 cm cosmological signal in mK units, as observed in the BINGO frequency band 16 (see Table 1): AME (top left), CMB (top right), free-free (middle left), faint radio point sources (FRPS) (middle right), synchrotron (bottom left), and the 21 cm log-normal cosmological signal (bottom right). All maps are shown in celestial coordinates, have a HEALPix resolution of N_side = 256, and are convolved with a 40′ beam.
