Fig. 10.


Comparison of the location of the known LAEs within the galaxy overdensity BOSS1441 and the SCUBA-2 submillimeter detections in our field of view (red; as in Fig. 1). We indicate the position of the LAEs (black circles), QSOs in the redshift range 2.30 ≤ z <  2.34 (brown crosses), detections at 850 μm (blue circles; the number indicates the observed flux in unit of mJy; the size of circles equals the FWHM), and detection at 450 μm (yellow squares; the size of symbol equals the FWHM). As in Fig. 1 we show the density contours (green) for LAEs in steps of 0.1 galaxies per arcmin2, with the inner density peak of 1.0 per arcmin2. We also highlight the position of the ELAN MAMMOTH-1 (dotted crosshair), and the field of view of our SCUBA-2 observations for 3× the central noise (red dashed contour). Overall, the LAEs and submillimeter sources are not associated. Only the ELAN MAMMOTH-1 and an additional LAE can be considered as counterparts of a submillimeter detection, MAM-850.14 and MAM-850.16 respectively (highlighted as orange diamonds). Intriguingly the brightest submillimeter detections coincide with the peak of the BOSS1441 overdensity.
