ALMA uncovers the [C II] emission and warm dust continuum in a z = 8.31 Lyman break galaxy
2020: Monthly Notices of the Royal Astronomical Society, Volume 493, Issue 3, p.4294-4307
In this paper [pdf], we report on the emission of Carbon at redshift z = 8.3, and the non-detection of dust emission. To date, this is the most distant detection of Carbon, and together with the previously-observed Oxygen, we expect this galaxy to have an extremely hard radiation field, unlike galaxies at lower redshifts. The non-detection of dust suggests an unusually-warm dust component, perhaps due to the source's high redshift.
IRAM 30m-EMIR Redshift Search of z = 3-4 Lensed Dusty Starbursts selected from the HerBS sample
ArXiV preprint
In this paper [pdf], we discuss the measurements of 4 spectroscopic redshifts, as part of a larger attempt to gather spectroscopic redshifts for all HerBS sources. They appear lensed by their velocity profile. Most importantly, perhaps, we present a new method for deriving spectroscopic redshifts -- away from tedious comparisons of tables -- with a graphical method.
  • Abstract
  • A search for the lenses in the Herschel Bright Sources (HerBS) sample
    2020: Monthly Notices of the Royal Astronomical Society, Volume 493, Issue 3, p.4276-4293
    In this paper [pdf], we perform a statistical method onto Herschel sources, comparing them to both optical and near-infrared galaxies. While the Herschel-objects themselves will most likely remain invisible in these optical and near-infrared observations, we attempt to find the foreground galaxies, that are the cause of the gravitational lensing inside many of these Herschel Bright Sources. We find that the optical observations do not have the depth to even find most foreground sources, but the near-infrared survey appears much more succesful. Finally, we measured for the first time the relationship between the flux of a source and it's probability to be gravitationally lensed; something that was suggested by models, but only now has been measured.
    Herschel Bright Sources (HerBS): Sample definition and SCUBA-2 observations
    2018: Monthly Notices of the Royal Astronomical Society, Volume 473, Issue 2, p.1751-1773
    In this paper [pdf], we explore the brightest, distant galaxies found in the H-ATLAS survey. We define a sample, and provide its catalogue, together with observations from the James Clerk Maxwell Telescope.

    First light demonstration of the integrated superconducting spectrometer
    Endo et al. 2019: Nature Astronomy, Volume 3, p. 989-996
    In this paper [pdf], Endo et al. report on the first astronomical observations using the revolutionary M-KID spectrometer on the ASTE telescope. In the precursor campaign, mapping on Orion, and targetted observations on a z = 0.05 Quasar showed DESHIMA's power as a redshift machine and in understanding ISM conditions.

    NOEMA redshift measurements of bright Herschel galaxies
    Neri et al. 2020: Astronomy & Astrophysics, Volume 635, id.A7, 17 pp.
    In this paper [pdf], Neri et al. report on the successful pilot project for finding spectroscopic redshifts using NOEMA. The large bandwidth, combined with the ability to adapt tunings between observations, enabled efficient observations at high resolution, showing a large fraction of intrinsically-luminous SMGs.

    Large Population of ALMA Galaxies at z>6 with Very High [OIII]88um to [CII]158um Flux Ratios: Evidence of Extremely High Ionization Parameter or PDR Deficit?
    Harikane et al. 2020
    In this paper [pdf], Harikane et al. report on three sources with Carbon, Oxygen and tentative Nitrogen lines. Their modelling using Cloudy to explain the nature of high-redshift sources is extensive, and well-written.

    The Herschel-ATLAS: a sample of 500 μm-selected lensed galaxies over 600 deg2
    Negrello et al. 2017: Monthly Notices of the Royal Astronomical Society, Volume 465, Issue 3, p.3558-3580
    In this paper [pdf], Negrello et al. report on the most likely lenses selected from the H-ATLAS survey, using both sub-mm and optical (Hubble) observations. Substantial overlap exists between this sample and HerBS, however this sample only selects > 100 mJy at 500 micron.
