    • 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 ...

    • Low-mass bursty galaxies in JADES efficiently produce ionizing photons and could represent the main drivers of reionization 

      Simmonds, C.; Tacchella, S.; Hainline, K.; Johnson, B. D.; McClymont, W.; Robertson, B.; Saxena, Aayush; Sun, Fengwu; Witten, C.; Baker, William M.; Bhatawdekar, R.; Boyett, K.; Bunker, A. J.; Charlot, S.; Curtis-Lake, E.; Egami, E.; Eisenstein, D. J.; Hausen, R.; Maiolino, R.; Maseda, M. V.; Scholtz, J.; Williams, C. C.; Willot, C.; Witstok, J. (2024-01-01)
      We use deep imaging from the JWST Advanced Deep Extragalactic Survey (JADES) to study the evolution of the ionizing photon production efficiency, ζion. We estimate ζion for a sample of 677 galaxies at z ∼4-9 using NIRCam ...
