    • The chemical enrichment in the early Universe as probed by JWST via direct metallicity measurements at z~8 

      Curti, M.; D'Eugenio, F.; Carniani, S.; Maiolino, R.; Sandles, L.; Witstok, J.; Baker, W. M.; Bennett, J. S.; Piotrowska, J. M.; Tacchella, S.; Charlot, S.; Nakajima, K.; Maheson, G.; Mannucci, F.; Amiri, A.; Arribas, S.; Belfiore, F.; Bonaventura, N. R.; Bunker, A. J.; Chevallard, J.; Cresci, G.; Curtis-Lake, E.; Hayden-Pawson, C.; Kumari, N.; Laseter, I.; Looser, T. J.; Marconi, A.; Maseda, M. V.; Jones, G. C.; Scholtz, J.; Smit, R.; Ubler, H.; Wallace, I. E. B. (2022-09-27)
      We analyse the chemical properties of three z~8 galaxies behind the galaxy cluster SMACS J0723.3-7327, observed as part of the Early Release Observations programme of the James Webb Space Telescope (JWST). Exploiting [O ...

    • 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 ...

C.; Wang, R.; Wang, Wei-Hao; Yang, Y.; Asquith, R.; Bourne, N.; Coppin, K.; Hine, N. K.; Ho, L. C.; Hwang, H. S.; Kato, Y.; Lacaille, K.; Lewis, A. J. R.; Oteo, I.; Scholtz, J.; Sawicki, M.; Smith, D. (2019-11-20)
      We identify multi-wavelength counterparts to 1,147 submillimeter sources from the S2COSMOS SCUBA-2 survey of the COSMOS field by employing a recently developed radio$+$machine-learning method trained on a large sample of ...
