“…Dust temperature vs. FIR luminosity. For comparison, other lensed and non-lensed galaxies are plotted, including the other Plank/Herscheldetected lensed galaxies (Canameras et al 2015), Herschel lensed galaxies (Bussmann et al 2013), as well as other lensed/unlensed SMGs and ULIRGs (Amblard et al 2010;Greve et al 2012). To make the comparison more instructive the lensed galaxies have had L FIR demagnified by a factor of five.…”

We present a source-plane reconstruction of a Herschel and Planck-detected gravitationally lensed dusty starforming galaxy (DSFG) at z=1.68 using Hubble, Submillimeter Array (SMA), and Keck observations. The background submillimeter galaxy (SMG) is strongly lensed by a foreground galaxy cluster at z=0.997 and appears as an arc with alength of ∼15″ in the optical images. The continuum dust emission, as seen by SMA, is limited to a single knot within this arc. We present a lens model with source-plane reconstructions at several wavelengths to show the difference in magnification between the stars and dust, and highlight the importance ofmulti-wavelength lens models for studies involving lensed DSFGs. We estimate the physical properties of the galaxy by fitting the flux densities to model spectral energy distributions leading to a magnification-corrected starformation rate (SFR) of 390±60 M  yr −1 and a stellar mass of 1.1 0.4 10 11  M . These values are consistent with high-redshift massive galaxies that have formed most of their stars already. The estimated gas-to-baryon fraction, molecular gas surface density, and SFR surface density have values of 0.43±0.13, 350±200  M pc −2 , and~ 12 7 M  yr −1 kpc −2 , respectively. The ratio of SFR surface density to molecular gas surface density puts this among the most star-forming systems, similar to other measured SMGs and local ULIRGs.

“…We refer to this as Model 1. Next, in attempting to address the growing observational evidence for evolving temperature with redshift (e.g., Pascale et al 2009;Amblard et al 2010;Viero et al 2013), we introduce an additional parameter, T z , such that T dust ∝ (1 + z) T z . Note that the β parameter remains a free variable without redshift evolution in this model, which we refer to as Model 2.…”

We present measurements of the auto-and cross-frequency power spectra of the cosmic infrared background (CIB) at 250, 350, and 500 μm (1200, 860, and 600 GHz) from observations totaling ∼70 deg 2 made with the SPIRE instrument aboard the Herschel Space Observatory. We measure a fractional anisotropy δI /I = 14% ± 4%, detecting signatures arising from the clustering of dusty star-forming galaxies in both the linear (2-halo) and nonlinear (1-halo) regimes; and that the transition from the 2-to 1-halo terms, below which power originates predominantly from multiple galaxies within dark matter halos, occurs at k θ ∼ 0.10-0.12 arcmin −1 ( ∼ 2160-2380), from 250 to 500 μm. New to this paper is clear evidence of a dependence of the Poisson and 1-halo power on the flux-cut level of masked sources-suggesting that some fraction of the more luminous sources occupy more massive halos as satellites, or are possibly close pairs. We measure the cross-correlation power spectra between bands, finding that bands which are farthest apart are the least correlated, as well as hints of a reduction in the correlation between bands when resolved sources are more aggressively masked. In the second part of the paper, we attempt to interpret the measurements in the framework of the halo model. With the aim of fitting simultaneously with one model the power spectra, number counts, and absolute CIB level in all bands, we find that this is achievable by invoking a luminosity-mass relationship, such that the luminosity-to-mass ratio peaks at a particular halo mass scale and declines toward lower and higher mass halos. Our best-fit model finds that the halo mass which is most efficient at hosting star formation in the redshift range of peak star-forming activity, z ∼ 1-3, is log(M peak /M ) ∼ 12.1 ± 0.5, and that the minimum halo mass to host infrared galaxies is log(M min /M ) ∼ 10.1 ± 0.6.

“…It is a maximum likelihood estimate and follows the approach used in Thacker et al (2013). We do not use the map-maker that was developed for anisotropy power spectrum measurement in (Amblard et al 2010) due to improvements that have been made to the HIPE and its bulitin map-makers since the Amblard et al study in 2010.…”

We present the cross-correlation between the far-infrared (far-IR) background fluctuations as measured with the Herschel Space Observatoryat 250, 350, and 500 μm and the near-infrared (near-IR) background fluctuations with the Spitzer Space Telescope at 3.6 and 4.5 μm. The cross-correlation between the FIR and NIR background anisotropies is detected such that the correlation coefficient at a few to 10 arcminute angular scale decreases from 0.3 to 0.1 when the FIR wavelength increases from 250 to 500 μm. We model the cross-correlation using a halo model with three components: (a) FIR bright or dusty star-forming galaxies below the masking depth in Herschel maps, (b) NIR faint galaxies below the masking depth, and (c) intra-halo light (IHL), or diffuse stars in dark matter halos, that is likely dominating the large-scale NIR fluctuations. The model is able to reasonably reproduce the auto-correlations at each of the FIR wavelengths and at 3.6 μm and their corresponding cross-correlations. While the FIR and NIR auto-correlations are dominated by faint, dusty, star-forming galaxies and IHL, respectively, we find that roughly half of the cross-correlation between the NIR and FIR backgrounds is due to the same dusty galaxies that remain unmasked at 3.6 μm. The remaining signal in the cross-correlation is due to IHL present in the same dark matter halos as those hosting the same faint and unmasked galaxies.
