    • ALMA Observations of Ly-alpha Blob 1: Halo Substructure Illuminated from Within 

      Geach, J.~E.; Narayanan, D.; Matsuda, Y.; Hayes, M.; Mas-Ribas, L.; Dijkstra, M.; Steidel, C.~C.; Chapman, S.~C.; Feldmann, R.; Avison, A.; Agertz, O.; Ao, Y.; Birkinshaw, M.; Bremer, M.~N.; Clements, D.~L.; Dannerbauer, H.; Farrah, D.; Harrison, C.~M.; Kubo, M.; Michalowski, M.~J.; Scott, D.; Spaans, M.; Simpson, J.~M.; Swinbank, A.~M.; Taniguchi, Y.; van der Werf, P.; Verma, A.; Yamada, T. (2016-11-14)
      We present new Atacama Large Millimeter/Submillimeter Array (ALMA) 850 μm continuum observations of the original Lyα Blob (LAB) in the SSA22 field at z = 3.1 (SSA22-LAB01). The ALMA map resolves the previously identified ...

    • The cosmic build-up of dust and metals : Accurate abundances from GRB-selected star-forming galaxies at 1.7 < z < 6.3 

      Heintz, K. E.; Cia, A. De; Thöne, C. C.; Krogager, J. -K.; Yates, R. M.; Vejlgaard, S.; Konstantopoulou, C.; Fynbo, J. P. U.; Watson, D.; Narayanan, D.; Wilson, S. N.; Arabsalmani, M.; Campana, S.; D'Elia, V.; Pasquale, M. De; Hartmann, D. H.; Izzo, L.; Jakobsson, P.; Kouveliotou, C.; Levan, A.; Li, Q.; Malesani, D. B.; Melandri, A.; Milvang-Jensen, B.; Møller, P.; Palazzi, E.; Palmerio, J.; Petitjean, P.; Pugliese, G.; Rossi, A.; Saccardi, A.; Salvaterra, R.; Savaglio, S.; Schady, P.; Stratta, G.; Tanvir, N. R.; Postigo, A. de Ugarte; Vergani, S. D.; Wiersema, K.; Wijers, R. A. M. J.; Zafar, T. (2023-11-15)
      The chemical enrichment of dust and metals in the interstellar medium of galaxies throughout cosmic time is one of the key driving processes of galaxy evolution. Here we study the evolution of the gas-phase metallicities, ...

    • A deep ALMA image of the Hubble Ultra Deep Field 

      Dunlop, J. S.; McLure, R. J.; Biggs, A. D.; Geach, J. E.; Michalowski, M. J.; Ivison, R. J.; Rujopakarn, W.; Kampen, E. van; Kirkpatrick, A.; Pope, A.; Scott, D.; Swinbank, A. M.; Targett, T. A.; Aretxaga, I.; Austermann, J. E.; Best, P. N.; Bruce, V. A.; Chapin, E. L.; Charlot, S.; Cirasuolo, M.; Coppin, K. E. K.; Ellis, R. S.; Finkelstein, S. L.; Hayward, C. C.; Hughes, D. H.; Ibar, E.; Khochfar, S.; Koprowski, M. P.; Narayanan, D.; Papovich, C.; Peacock, J. A.; Robertson, B.; Vernstrom, T.; Werf, P. P. van der; Wilson, G. W.; Yun, M. (2017-04-01)
      We present the results of the first, deep ALMA imaging covering the full 4.5 sq arcmin of the Hubble Ultra Deep Field (HUDF) as previously imaged with WFC3/IR on HST. Using a mosaic of 45 pointings, we have obtained a ...

    • An orientation bias in observations of submillimetre galaxies 

      Lovell, C. C.; Geach, J. E.; Davé, R.; Narayanan, D.; Coppin, K. E. K.; Li, Q.; Franco, M.; Privon, G. C. (2022-07-28)
      Recent high-resolution interferometric images of submillimetre galaxies (SMGs) reveal fascinatingly complex morphologies. This raises a number of questions: how does the relative orientation of a galaxy affect its observed ...

    • VLA and ALMA IMAGING of INTENSE GALAXY-WIDE STAR FORMATION in z ∼ 2 GALAXIES 

      Rujopakarn, W.; Dunlop, J. S.; Rieke, G. H.; Ivison, R. J.; Cibinel, A.; Nyland, K.; Jagannathan, P.; Silverman, J. D.; Alexander, D. M.; Biggs, A. D.; Bhatnagar, S.; Ballantyne, D. R.; Dickinson, M.; Elbaz, D.; Geach, J. E.; Hayward, C. C.; Kirkpatrick, A.; McLure, R. J.; Michałowski, M. J.; Miller, N. A.; Narayanan, D.; Owen, F. N.; Pannella, M.; Papovich, C.; Pope, A.; Rau, U.; Robertson, B. E.; Scott, D.; Swinbank, A. M.; Werf, P. Van Der; Kampen, E. Van; Weiner, B. J.; Windhorst, R. A. (2016-12-01)
      We present ≃0.″4 resolution extinction-independent distributions of star formation and dust in 11 star-forming galaxies (SFGs) at z = 1.3-3.0. These galaxies are selected from sensitive blank-field surveys of the 2′ ×2′ ...
