“…Thus, radio sub-selection has cut off the high-z tail of the 850µm distribution (as indicated by the hashed gray area on Figure 17). This is confirmed by the phenomenological models of Chapman et al (2003b) and Lewis et al (2005) who surmise that there should be a missing population of SMGs at high-z not detected in the radio. Chapman et al also describe how radio sub-selection can also select against very cold-dust SMGs, as they'll have much higher S 850 /S 1.4 ratios than typical SMGs.…”

“…An updated version of the Chapman et al redshift distribution is shown as a dashed-blue line, including DEIMOS-observed radio SMGs from Banerji et al (2011) specifically targeted to fill the redshift desert gap of LRIS, and a handful of high-z 850µm-selected SMGs Daddi et al, 2009;Walter et al, 2012). Also over-plotted is the Lewis et al (2005) and Chapman et al (2003b) phenomenological model 850µm SMG redshift distribution without radio flux selection (dark green dot dashed line). We also over-plot the Wardlow et al (2011) redshift distribution for the LESS 870µm sample in CDFS (red line filled histogram) and the update to that sample−courtesy of ALMA follow-up establishing unambiguous counterparts− from Simpson et al (2013) in orange.…”

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.

“…It should be noticed that the radio preselection biases the sample against very high redshifts (z <3) because the radio flux at 1.4 GHz is below the detection limit of the VLA surveys used for this preselection. A model by Chapman et al (2003b) and by Lewis et al (2005) illustrate this effect very well ( Figure 7). A fraction of the submillimeter-selected sources are missed in such a process at z > 3 (detectability in radio) and around z ∼1.5 (optical redshifts desert).…”

“…Nevertheless the submillimeter-selected sources do not appear qualitatively different from the optically-faint-radio selected ones. Another bias is the effect of the dust effective temperature of the SMGs (Lewis et al 2005). At a given total far-infrared luminosity, hotter sources have lower submillimeter fluxes if the radio/far-infrared correlation continues to hold.…”

The discovery of the Cosmic Infrared Background (CIB) in 1996, together with recent cosmological surveys from the mid-infrared to the millimeter have revolutionized our view of star formation at high redshifts. It has become clear, in the last decade, that a population of galaxies that radiate most of their power in the far-infrared (the so-called "infrared galaxies") contributes an important part of the whole galaxy build-up in the Universe. Since 1996, detailed (and often painful) investigations of the high-redshift infrared galaxies have resulted in the spectacular progress covered in this review. We outline the nature of the sources of the CIB including their star-formation rate, stellar and total mass, morphology, metallicity and clustering properties. We discuss their contribution to the stellar content of the Universe and their origin in the framework of the hierarchical growth of structures. We finally discuss open questions for a scenario of their evolution up to the present-day galaxies.

“…Pioneering works have measured the local luminosity function (Dunne et al 2000) and shown that most milli-Jansky sources lie at redshifts z > 2 Chapman et al 2003aChapman et al , 2005Ivison et al 2005;Pope et al 2005Pope et al , 2006. Other works showed that the galaxies SED selected in the submillimeter range (Benford et al 1999;Chapman et al 2003b;Sajina et al 2003;Lewis et al 2005;Beelen et al 2006;Kovács et al 2006;Sajina et al 2006;Michałowski et al 2010) can have typically warmer temperatures and higher luminosities than galaxies selected at other infrared wavelengths.…”

Context. The instrument BLAST (Balloon-borne Large-Aperture Submillimeter Telescope) performed the first deep and wide extragalactic survey at 250, 350 and 500 μm. The extragalactic number counts at these wavelengths are important constraints for modeling the evolution of infrared galaxies. Aims. We estimate the extragalactic number counts in the BLAST data, which allow a comparison with the results of the P(D) analysis of Patanchon et al. (2009). Methods. We use three methods to identify the submillimeter sources. 1) Blind extraction using an algorithm when the observed field is confusion-limited and another one when the observed field is instrumental-noise-limited. The photometry is computed with a new simple and quick point spread function (PSF) fitting routine (FASTPHOT). We use Monte-Carlo simulations (addition of artificial sources) to characterize the efficiency of this extraction, and correct the flux boosting and the Eddington bias. 2) Extraction using a prior. We use the Spitzer 24 μm galaxies as a prior to probe slightly fainter submillimeter flux densities. 3) A stacking analysis of the Spitzer 24 μm galaxies in the BLAST data to probe the peak of the differential submillimeter counts. Results. With the blind extraction, we reach 97 mJy, 83 mJy and 76 mJy at 250 μm, 350 μm and 500 μm respectively with a 95% completeness. With the prior extraction, we reach 76 mJy, 63 mJy, 49 mJy at 250 μm, 350 μm and 500 μm respectively. With the stacking analysis, we reach 6.2 mJy, 5.2 mJy and 3.5 mJy at 250 μm, 350 μm and 500 μm respectively. The differential submillimeter number counts are derived, and start showing a turnover at flux densities decreasing with increasing wavelength. (2009) models slightly overestimate the observed counts, but the data agree very well near the peak of the differential number counts. Models predict that the galaxy populations probed at the peak are likely z ∼ 1.8 ultra-luminous infrared galaxies.
