“…38) shows that roughly (14±8)% of DSFGs with S 250 > 30 mJy appear as satellites in more massive halos than ∼ 10 12 M . We note that slightly different results related to galaxy clustering at Spire wavelengths is reported in Maddox et al (2010). At low-redshifts with z < 0.5, the clustering of DSFGs are similar to blue, star-forming galaxies with a correlation length ∼ 4.6 ± 0.5 Mpc Guo et al, 2011) and are less-clustered than the dark matter distribution with a linear bias factor less than one (b = 0.7 ± 0.1).…”

Dusty star-forming galaxies at high redshift

Far-infrared and submillimeter wavelength surveys have now established the important role of dusty, star-forming galaxies (DSFGs) in the assembly of stellar mass and the evolution of massive galaxies in the Universe. The brightest of these galaxies have infrared luminosities in excess of 10 13 L with implied star-formation rates of thousands of solar masses per year. They represent the most intense starbursts in the Universe, yet many are completely optically obscured. Their easy detection at submm wavelengths is due to dust heated by ultraviolet radiation of newly forming stars. When summed up, all of the dusty, star-forming galaxies in the Universe produce an infrared radiation field that has an equal energy density as the direct starlight emission from all galaxies visible at ultraviolet and optical wavelengths. The bulk of this infrared extragalactic background light emanates from galaxies as diverse as gas-rich disks to mergers of intense starbursting galaxies. Major advances in far-infrared instrumentation in recent years, both spacebased and ground-based, has led to the detection of nearly a million DSFGs, yet our understanding of the underlying astrophysics that govern the start and end of the dusty starburst phase is still in nascent stage. This review is aimed at summarizing the current status of DSFG studies, focusing especially on the detailed characterization of the bestunderstood subset (submillimeter galaxies, who were summarized in the last review of this field over a decade ago, Blain et al. 2002), but also the selection and characterization of more recently discovered DSFG populations. We review DSFG population statistics, their physical properties including dust, gas and stellar contents, their environments, and current theoretical models related to the formation and evolution of these galaxies.

“…For the 250 μm channel on Herschel, for example, this means that no matter how deeply you observe a field, without some sort of spatial deconvolution at best only ∼15% of the flux density will be resolved into individually detected galaxies (Oliver et al 2010b). Adding to that the fact that the redshift distribution of DSFGs is relatively broad (e.g., Casey et al 2012;Chapman et al 2005;Béthermin et al 2012c), clustering measurements of resolved sources have consequently had limited success (e.g., Blain et al 2004;Scott et al 2006;Weiß et al 2009) and somewhat contradictory results (e.g., Cooray et al 2010;Maddox et al 2010).…”

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.

“…Gilli et al (2007) showed a correlation function of Spitzer MIPS 24-μm-selected galaxies at z ∼ 1, whose power-law slope is ∼1.5. Maddox et al (2010) analyzed the clustering of submillimeter galaxies detected by Herschel in the H-ATLAS survey. They have found a very steep slope of γ ∼ 2.0.…”

“…More recently, the angu-lar clustering analysis of Spitzer surveys (e.g., Oliver et al, 2004;de la Torre et al, 2007;Gilli et al, 2007;Magliocchetti et al, 2008), based mainly on mid-infrared (MIR) data, has been performed. Now, thanks to large space facilities, such as Herschel and Planck, results from longer wavelengths start to appear (e.g., Maddox et al, 2010;Cooray et al, 2010;Amblard et al, 2011;Magliocchetti et al, 2011;Planck Collaboration et al, 2011). With the data from the WISE satellite (Wright et al, 2010) we may soon hope for the all-sky measurement of MIR galaxies.…”

Clustering of far-infrared galaxies in the AKARI All-Sky Survey North

We present the measurements of the angular two-point correlation function for AKARI 90-μm point sources, detected outside the Milky Way plane and other regions characterized by high Galactic extinction in the northern Galactic hemisphere, and categorized as extragalactic sources according to our far-infrared-color based criterion. Together with our previous work this is the first measurement of the large-scale angular clustering of galaxies selected in the far-infrared after IRAS. We present the first attempt to estimate the spatial clustering properties of AKARI All-Sky galaxies and we conclude that they are mostly a very nearby (z ≤ 0.1) population of moderately clustered galaxies. We measure their correlation length r 0 ∼ 4.5 h −1 Mpc, which is consistent with the assumption that the FIS AKARI All-Sky surveys observes mostly a nearby star-forming population of galaxies.
