Location of the Lyα emitting sources detected in the AzTEC-3 environment. The ones with Lyα central wavelength larger (red) and smaller (blue) than that of the AzTEC-3 system are shown as small circles. The AzTEC-3 submillimeter and the LBG-3 galaxies are shown as yellow star and yellow diamond. Sources from the literature with photometric redshifts consistent with z ∼ 5.3 are also shown, five COSMOS2015 sources with 4.9 < z_phot < 5.6 (cyan big circles), Lyman break galaxies listed in Capak et al. (2011), but without Lyα emission in our MUSE datacube (green squares), one CO detection from Pavesi et al. (2018a) at z = 5.3 (gray circle). The black cross is the center of coordinates of all the sources shown in the figure and the gray cross the center obtained without considering AzTEC-3. The blue is the center of coordinates only of the sources with stellar mass larger than 10⁹ M_⊙ and the red cross is the weighted mass barycenter of the Lyα emitting sources detected in the field. The green cross is the weighted mass barycenter of the sources with a stellar mass estimation but without considering AzTEC-3.
