ATCA 20 cm, Spitzer MIPS 24 μm, and Herschel  PACS and SPIRE data for the four Lyα  blobs (LABs) in J2143-4423. a) Contours and gray scale maps of ATCA radio emission. The contours are −2, 2, 3, 4, 5, and 6 × 15μJy (1σ), with a synthesized beam of 7.8″ × 4.8″, which is shown in the lower left corner of each panel. b) Gray maps of Spitzer MIPS 24 μm emission (Colbert et al. 2006). c)–g) Contours and gray scale maps of Herschel  FIR emission. The contours are −2σ, 2σ, 3σ, 4σ, 5σ, and 6σ (see Sect. 2.2 for the noise level of each band). A circle with a diameter of 40″ is shown in each panel. The circles in B7  are in an off-center position (5″, 0″) to cover the most FIR emission. All sources are centered on the positions of the four LABs (see Colbert et al. 2006) as shown with plus signs in each panel. All offsets are relative to the positions of the LABs.
