“…A measurement of κ at Herschel wavelengths (but for local normal galaxies) has been attempted by Weibe et al (2009) andEales et al (2010b). Both works, however, suggest a much lower value for κ, which would increase the dust masses estimated here by a factor of ∼3.…”

“…Dust emission is often used as an indicator of the current star formation rate (SFR) in galaxies -although this calibration makes the assumption that young, massive stars are the main source of heating for the dust and that the majority of the UV photons from the young stars are absorbed and re-radiated by dust (Kennicutt 1998;Kennicutt et al 2009;Calzetti et al 2007). Many surveys of dust emission from 24 to 850 μm (Saunders et al 1990;Blain et al 1999;Le Floc'h et al 2005;Dye et al 2010;Eales et al 2010b;Gruppioni et al 2010) have noted the very strong evolution present in these bands and this is usually ascribed to a decrease in the SFR density over the past 8 billion years of cosmic history (z ∼ 1; Madau et al 1995;Hopkins 2004). The interpretation of this evolution is complicated by the fact that the dust luminosity of a galaxy is a function of both the dust content and the temperature of the dust.…”

We present the first direct and unbiased measurement of the evolution of the dust mass function of galaxies over the past 5 billion years of cosmic history using data from the Science Demonstration Phase of the Herschel‐Astrophysical Terahertz Large Area Survey (Herschel‐ATLAS). The sample consists of galaxies selected at 250 m which have reliable counterparts from the Sloan Digital Sky Survey (SDSS) at z < 0.5, and contains 1867 sources. Dust masses are calculated using both a single‐temperature grey‐body model for the spectral energy distribution and also a model with multiple temperature components. The dust temperature for either model shows no trend with redshift. Splitting the sample into bins of redshift reveals a strong evolution in the dust properties of the most massive galaxies. At z= 0.4–0.5, massive galaxies had dust masses about five times larger than in the local Universe. At the same time, the dust‐to‐stellar mass ratio was about three to four times larger, and the optical depth derived from fitting the UV‐sub‐mm data with an energy balance model was also higher. This increase in the dust content of massive galaxies at high redshift is difficult to explain using standard dust evolution models and requires a rapid gas consumption time‐scale together with either a more top‐heavy initial mass function (IMF), efficient mantle growth, less dust destruction or combinations of all three. This evolution in dust mass is likely to be associated with a change in overall interstellar medium mass, and points to an enhanced supply of fuel for star formation at earlier cosmic epochs.

“…The total gas mass (M gas , which incorporates both the molecular and atomic phases) can be inferred from the dust mass through the metallicity dependent gas-to-dust ratio (GDR, e.g. Eales et al 2010;Magdis et al 2012a): M gas = M dust /GDR(Z). For consistency with M gas estimates of SBs in the literature, we adopt GDR ≈ 30, that based on Magdis et al (2012a) corresponds to a CO-to-M gas α co conversion factor of 0.8 M / (K km s −1 pc 2 ), typically used for strong starbursts.…”

We investigate a sample of 152 dusty sources at 1.5 < z < 2.5 to understand the connection of enhanced Star-Formation-Rate (SFR) and Black-Hole-Accretion-Rate (BHAR). The sources are Herschel-selected, having stellar masses M * > 10 10 M and SFR (∼ 100 − 1000M /yr) elevated (> 4×) above the star-forming "main sequence", classifying them as Starbursts (SB). Through a multiwavelength fitting approach (including a dusty torus component), we divided the sample into active SBs (dominated by an AGN emission, SBs-AGN, ∼ 23% of the sample) and purely star-forming SBs (SBs-SFR). We visually inspected their HST/UV-restframe maps: SBs-SFR are generally irregular and composite systems; ∼ 50% of SBs-AGN are instead dominated by regular compact morphologies.

“…Luminosity functions based on observations at 250, 350 and 500 μm from the recent Balloon-borne Large Aperture Submillimeter Telescope (BLAST) survey centred on the GOODS-South field have shown a strong increase in the number density of the most luminous galaxies from the present out to z = 1 (Eales et al 2009). Two recent papers have presented luminosity functions using observations at 250 μm from the science demonstration phase of the Herschel Space Telescope: Dye et al (2010) used data from a 14 deg 2 field out to z = 0.5, showing steady evolution out to this redshift and Eales et al (2010) in two smaller but deeper fields to z = 2.0 found strong evolution out to z ∼ 1 but at most weak evolution beyond this redshift.…”

We present a far‐infrared galaxy luminosity function for the local universe. We have obtained 389 spectroscopic redshifts for galaxies observed at 90 μm in the AKARI Deep Field‐South, using the AAOmega fibre spectrograph via optical identifications in the digitized sky survey and 4‐m class optical imaging. For the luminosity function presented in this paper, we have used those galaxies which have redshifts 0 < z < 0.25, have optical magnitudes and are not part of a newly discovered cluster of galaxies (giving a total of 130 sources). Infrared and optical completeness functions were estimated using earlier Spitzer data and automated plate measurement (APM) B‐band optical data, respectively, and the luminosity function has been prepared using the 1/Vmax method. We also separate the luminosity function between galaxies which show evidence of predominantly star‐forming activity and predominantly active galactic nucleus (AGN) activity in their optical spectra. Our luminosity function is in good agreement with the previous 90‐μm luminosity function from the European Large Area Infrared Space Observatory (ISO) Survey, and we also present a luminosity function with combined AKARI and ISO data. The result is in reasonable agreement with predictions based on the earlier Infrared Astronomical Satellite (IRAS) m PSCz catalogue, and with a recent backward evolution model.
