    • Beware the recent past: a bias in spectral energy distribution modelling due to bursty star formation 

      Haskell, P.; Das, S.; Smith, D. J. B.; Cochrane, R. K.; Hayward, Christopher C.; Anglés-Alcázar, Daniel (2024-03-19)
      We investigate how the recovery of galaxy star formation rates (SFRs) using energy-balance spectral energy distribution (SED) fitting codes depends on their recent star formation histories (SFHs). We use the Magphys and ...

    • The case for a 'sub-millimeter SDSS' : a 3D map of galaxy evolution to z~10 

      Geach, James E.; Banerji, Manda; Bertoldi, Frank; Bethermin, Matthieu; Casey, Caitlin M.; Chen, Chian-Chou; Clements, David L.; Cicone, Claudia; Combes, Francoise; Conselice, Christopher; Cooray, Asantha; Coppin, Kristen; Daddi, Emanuele; Dannerbauer, Helmut; Dave, Romeel; Doherty, Matthew; Dunlop, James S.; Edge, Alastair; Farrah, Duncan; Franco, Maximilien; Fuller, Gary; Garratt, Tracy; Gear, Walter; Greve, Thomas R.; Hatziminaoglou, Evanthia; Hayward, Christopher C.; Ivison, Rob J.; Kawabe, Ryohei; Klaassen, Pamela; Knudsen, Kirsten K.; Kohno, Kotaro; Koprowski, Maciej; Lagos, Claudia D. P.; Magdis, Georgios E.; Magnelli, Benjamin; McGee, Sean L.; Michalowski, Michal; Mroczkowski, Tony; Noroozian, Omid; Oliver, Seb; Riechers, Dominik; Rujopakarn, Wiphu; Scott, Douglas; Serjeant, Stephen; Smith, Matthew W. L.; Swinbank, Mark; Tamura, Yoichi; Werf, Paul van der; Kampen, Eelco van; Verma, Aprajita; Vieira, Joaquin; Wagg, Jeff; Walter, Fabian; Wang, Lingyu; Wootten, Al; Yun, Min S. (2019-05-31)
      The Sloan Digital Sky Survey (SDSS) was revolutionary because of the extraordinary breadth and ambition of its optical imaging and spectroscopy. We argue that a 'sub-millimeter SDSS' - a sensitive large-area imaging+spectroscopic ...

    • Chaotic and Clumpy Galaxy Formation in an Extremely Massive Reionization-era Halo 

      Spilker, Justin S.; Hayward, Christopher C.; Marrone, Daniel P.; Aravena, Manuel; Béthermin, Matthieu; Burgoyne, James; Chapman, Scott C.; Greve, Thomas R.; Gururajan, Gayathri; Hezaveh, Yashar D.; Hill, Ryley; Litke, Katrina C.; Lovell, Christopher C.; Malkan, Matthew A.; Murphy, Eric J.; Narayanan, Desika; Phadke, Kedar A.; Reuter, Cassie; Stark, Antony A.; Sulzenauer, Nikolaus; Vieira, Joaquin D.; Vizgan, David; Weiß, Axel (2022-04-08)
      Abstract: The SPT 0311–58 system at z = 6.900 is an extremely massive structure within the reionization epoch and offers a chance to understand the formation of galaxies at an extreme peak in the primordial density field. ...

    • Deriving star formation histories from photometry using energy balance spectral energy distribution modelling 

      Smith, Daniel; Hayward, Christopher C. (2015-10-21)
      Panchromatic spectral energy distribution (SED) fitting is a critical tool for determining the physical properties of distant galaxies, such as their stellar mass and star formation rate. One widely used method is the ...

    • Observational constraints on the physical nature of submillimetre source multiplicity : chance projections are common 

      Hayward, Christopher C.; Chapman, Scott C.; Steidel, Charles C.; Golob, Anneya; Casey, Caitlin M.; Smith, Daniel J. B.; Zitrin, Adi; Blain, Andrew W.; Bremer, Malcolm N.; Chen, Chian-Chou; Coppin, Kristen E. K.; Farrah, Duncan; Ibar, Eduardo; Michałowski, Michał J.; Sawicki, Marcin; Scott, Douglas; Werf, Paul van der; Fazio, Giovanni G.; Geach, James E.; Gurwell, Mark; Petitpas, Glen; Wilner, David J. (2018-05-11)
      Interferometric observations have demonstrated that a significant fraction of single-dish submillimetre (submm) sources are blends of multiple submm galaxies (SMGs), but the nature of this multiplicity, i.e. whether the ...

    • Panchromatic SED modelling of spatially-resolved galaxies 

      Smith, Daniel J. B.; Hayward, Christopher C. (2018-05-11)
      We test the efficacy of the energy-balance spectral energy distribution (SED) fitting code MAGPHYS for recovering the spatially resolved properties of a simulated isolated disc galaxy, for which it was not designed. We ...
