    • Evidence for cosmic acceleration with next-generation surveys: A model-independent approach 

      Bengaly, Carlos A. P. (Oxford University Press, 2020)
      We quantify the evidence for cosmic acceleration using simulations of H(z) measurements from SKA- and Euclid-like surveys. We perform a non-parametric reconstruction of the Hubble parameters and its derivative to obtain ...

      Jiang, Linhua; Egami, Eiichi; Fan, Xiaohui; Dave, Romeel (IOP Science, 2013)
      We present a detailed structural and morphological study of a large sample of spectroscopicallyconfirmed galaxies at z ≥ 6, using deep HST near-IR broad-band images and Subaru optical narrowband images. The galaxy sample ...

      Akrami, Yashar; Arroja, Frederico; Ashdown, Mark A.J. (EDP Sciences, 2020)
      This paper presents the High Frequency Instrument (HFI) data processing procedures for the Planck 2018 release. Major improvements in mapmaking have been achieved since the previous Planck 2015 release, many of which were ...
    • Planck 2018 results: VI. Cosmological parameters 

      Aghanim, Nabila; Akrami, Yashar; Ashdown, Mark A.J. (EDP Sciences, 2020)

    • Properties of submillimeter galaxies in the CANDELS GOODS-south field 

      Wilklind, Tommy; Conselice, Christopher J.; Dave, Romeel (American Physical Society, 2014)
      We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field. The galaxies were first identified as submillimeter sources with the LABOCA bolometer and subsequently targeted ...
