Probing the effect of the protocluster environment on galaxy morphology at z = 2.23

Fig. 3.

Image cutouts of a selection of HST WFC3 F160W detected multi-peak galaxies identified in BOSS1244 (top row) and BOSS1542 (bottom row). Each cutout is 2 $\overset{″}{.}$ ${{\overset{\prime\prime}{.}}}$ 88 × 2 $\overset{″}{.}$ ${{\overset{\prime\prime}{.}}}$ 88. The size of the FWHM of the HST WFC3 F160W PSF is shown as the black circle in the bottom of each cutout. These galaxies were detected as a singular galaxy with SOURCE EXTRACTOR/GALAPAGOS, but show multiple bright peaks, potentially indicative of a merging and/or clumpy galaxy.
