Appendix A: Candidate Hα emitting galaxies around TXS 2353-003

thumbnail Fig. A.1

Hα emitters around TXS 2353-003 selected by the Bunker plot and confirmed when subtracting the continuum from the NB image. Left column: H-band images of the candidates. Middle column: NB1.64 images of the candidates. Right columns: continuum-subtracted NB images of the candidates, the last column showing them smoothed with a Gaussian kernel of σ = 1 pixel. The color palette spans − 3σ to + 5σ in each case in order to highlight the faint features of these HAE candidates. The contours give the morphology of the sources at larger surface brightnesses: white contours are at levels 3; 5; 10; 15; 20 σ and the black contours are at levels − 10; − 5; − 3σ. The HzRG is labeled “a”.
