JWST Quintet (IMAGE)
Caption
The pseudo-color images of JWST’s Quintet at redshift 6.71. a) The pseudocolor image created from NIRCam F115W (blue), F150W (green), and F200W (red) images. The five emission line galaxies in JWST’s Quintet (JQ) are indicated by large orange circles and labeled (ELG1–ELG5). Small purple labels denote seven foreground galaxies at different redshifts and are unassociated with the JQ. The white bar in the lower right shows a physical scale of 5 pkpc. b) The pseudo-color image created from NIRCam F277W (blue), F356W (green), and F444W (red) images. The F356W (green) filter contains the diffuse emission of redshifted [O III]+Hβ, which is visible in
the pseudo-color image. c) Similar to a, but with the foreground galaxies removed. Red labels (C1 – C16) mark clumps belonging to the JQ galaxies. d) Similar to b, but with the foreground galaxies removed. In panels c and d the diffuse [O III]+Hβ halo is shown by the green contours. We estimate
the stellar continuum of clumps from the SED fitting and subtract their contribution from the F356W image to obtain the [O III]+Hβ contour map of JQ (see Methods). Here, we present the smoothed [O III]+Hβ map using a Gaussian kernel with a width of 1 pixel (0.03 arcsec). In Extended Data
Figure 4, we present the unsmoothed [O III]+Hβ map. We show contour levels 2, 5, 10, and 15 σ, which indicate surface brightnesses of [8.8, 22, 44, 66] ×10−17 erg s−1 cm−2 arcsec−2.
