ALMA observations of the long wavelength dust continuum are used to estimate the interstellar medium (ISM) masses in a sample of 708 galaxies at z=0.3 to 4.5 in the COSMOS field. The galaxy sample has known farinfrared luminosities and, hence, star formation rates (SFRs) and stellar masses ( * M ) from the optical-infrared spectrum fitting. The galaxies sample SFRs from the main sequence (MS) to 50 times above the MS. The derived ISM masses are used to determine the dependence of gas mass on redshift, * M , and specific SFR (sSFR) relative to the MS. The ISM masses increase approximately with the 0.63 power of the rate of increase in SFRs with redshift and the 0.32 power of the sSFR/sSFR MS . The SF efficiencies also increase as the 0.36 power of the SFR redshift evolution and the 0.7 power of the elevation above the MS; thus the increased activities at early epochs are driven by both increased ISM masses and SF efficiency. Using the derived ISM mass function, we estimate the accretion rates of gas required to maintain continuity of the MS evolution (>  M 100 yr −1 at z > 2.5). Simple power-law dependencies are similarly derived for the gas accretion rates. We argue that the overall evolution of galaxies is driven by the rates of gas accretion. The cosmic evolution of total ISM mass is estimated and linked to the evolution of SF and active galactic nucleus activity at early epochs.

“…Note that these are different from the canonical pixel sizes used for maps in the Herschel Science Archive, which use 3.2, 3.2 6, 10, and 14 arcsec, respectively. The maps made with the PACS camera (100 and 160 μm, Poglitsch et al 2010) have units of Jy per pixel. The maps made with the SPIRE camera (250, 350, and 500 μm, Griffin et al 2010) have units of Jy per beam.…”

The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) is a survey of 660 deg 2 with the PACS and SPIRE cameras in five photometric bands: 100, 160, 250, 350, and 500 μm. This is the second of three papers describing the data release for the large fields at the south and north Galactic poles (NGP and SGP). In this paper we describe the catalogs of far-infrared and submillimeter sources for the NGP and SGP, which cover 177.1 deg 2 and 303.4 deg 2 , respectively. The catalogs contain 118,908 sources for the NGP field and 193,527 sources for the SGP field detected at more than 4σ significance in any of the 250, 350, or 500 μmbands. The source detection is based on the 250 μm map, and we present photometry in all five bands for each source, including aperture photometry for sources known to be extended. The rms positional accuracy for the faintest sources is about 2.4 arcsec in both R.A. and decl. We present a statistical analysis of the catalogs and discuss the practical issuescompleteness, reliability, flux boosting, accuracy of positions, accuracy of flux measurements-necessary to use the catalogs for astronomical projects.

“…For the purposes of the current work, the final hub mirror was simply given an over-sized radius of 600 mm to ensure a low level of truncation at all wavelengths. No attention is given here to the specifics of the other internal hub optics, since a number of optical layouts could be chosen for a range of science instruments based on heritage from the Herschel Space Observatory [17,18,19], or indeed the research to date on the planned SPICA mission [20,21]. What is certain though, is that the design of the hub optics for a future mission will require great care if beam truncation is to be minimised.…”

FISICA (Far-Infrared Space Interferometer Critical Assessment) was a three year study aimed at designing a far-infrared spatio-spectral double-Fourier interferometer concept. This paper describes a two-telescope (and hub) baseline optical design, that fulfills the requirements of the FISICA science case. Due the physical size of far-infrared wavelengths with respect to the size of the required optics, a number of different analysis techniques were required for the design work. Approximate simulation tools such as ray tracing and Gaussian beam mode (GBM) methods were employed for initial analysis, with GRASP PO (physical optics) used for final analysis for higher accuracy. The work builds on previous far-infrared double
