“…The excess of extreme starbursts within protoclusters found in some observational studies (e.g. Blain et al 2004;Capak et al 2011;Ivison et al 2013) is consistent with this idea. Because of the lack of spectroscopic data, we cannot discriminate between star formation and AGN activities.…”

“…maps, and created samples containing 77 and 80 sources, respectively. Spectroscopic and optical follow-up observations were able, so far, to confirm that 20 sources are indeed lensed, one is a proto-cluster (Ivison et al 2013), while the remaining sources in Negrello et al (2017) await more observations to be carried out to confirm their nature.…”

We present the Herschel Bright Sources (HerBS) sample, a sample of bright, high-redshift Herschel sources detected in the 616.4 square degree H-ATLAS survey. The HerBS sample contains 209 galaxies, selected with a 500 µm flux density greater than 80 mJy and an estimated redshift greater than 2. The sample consists of a combination of HyLIRGs and lensed ULIRGs during the epoch of peak cosmic star formation. In this paper, we present SCUBA-2 observations at 850 µm of 189 galaxies of the HerBS sample, 152 of these sources were detected. We fit a spectral template to the Herschel-SPIRE and 850 µm SCUBA-2 flux densities of 22 sources with spectroscopically determined redshifts, using a two-component modified blackbody spectrum as a template. We find a cold-and hot-dust temperature of 21.29 +1.35 −1.66 K and 45.80 +2.88 −3.48 K, a cold-to-hot dust mass ratio of 26.62 +5.61 −6.74 and a β of 1.83 +0.14 −0.28 . The poor quality of the fit suggests that the sample of galaxies is too diverse to be explained by our simple model. Comparison of our sample to a galaxy evolution model indicates that the fraction of lenses is high. Out of the 152 SCUBA-2 detected galaxies, the model predicts 128.4 ± 2.1 of those galaxies to be lensed (84.5%). The SPIRE 500 µm flux suggests that out of all 209 HerBS sources, we expect 158.1 ± 1.7 lensed sources, giving a total lensing fraction of 76 per cent.

“…With more unlensed analogues of groups and recent mergers in the literature (e.g. Frayer et al 1998;Ivison et al 1998Ivison et al , 2010aIvison et al , 2013Borne et al 2000;Tacconi et al 2008) and the ALMA multiplicity results from Hodge et al (2013), it is clear that mergers and interactions play an important role for many SMGs. These distant galaxy groups are akin to nearby compact groups (Hickson 1982), with the z ∼ 2.9 galaxy group presented here reminiscent perhaps to Stephan's Quintet (Stephan 1877), due to the remarkable number of galaxies associated with this submm source.…”

MS 0451.6−0305 is a rich galaxy cluster whose strong lensing is particularly prominent at submm wavelengths. We combine new SCUBA-2 data with imaging from Herschel SPIRE and PACS and HST in order to try to understand the nature of the sources being lensed. In the region of the "giant submm arc," we uncover seven multiply imaged galaxies (up from the previously known three), of which six are found to be at a redshift of z ∼ 2.9, and possibly constitute an interacting system. Using a novel forward-modelling approach, we are able to simultaneously deblend and fit SEDs to the individual galaxies that contribute to the giant submm arc, constraining their dust temperatures, far infrared luminosities and star formation rates. The submm arc first identified by SCUBA can now be seen to be composed of at least five distinct sources, four of these within the galaxy group at z ∼ 2.9. The total unlensed luminosity for this galaxy group is (3.1 ± 0.3) × 10 12 L , which gives an unlensed star formation rate of (450 ± 50) M yr −1 . From the properties of this system, we see no evidence of evolution towards lower temperatures in the dust temperature versus far-infrared luminosity relation for high redshift galaxies.
