    • Galaxy Zoo : the dependence of the star formation-stellar mass relation on spiral disk morphology 

      Willett, Kyle W.; Schawinski, Kevin; Simmons, Brooke D.; Masters, Karen L.; Skibba, Ramin A.; Kaviraj, Sugata; Melvin, Thomas; Wong, O. Ivy; Nichol, Robert C.; Cheung, Edmond; Lintott, Chris J.; Fortson, Lucy (2015-03-19)
      We measure the stellar mass-star formation rate relation in star-forming disk galaxies at z1. Of the galaxies lying significantly above the M-SFR relation in the local Universe, more than 50% are mergers. We interpret this ...

    • The green valley is a red herring : Galaxy Zoo reveals two evolutionary pathways towards quenching of star formation in early-and late-type galaxies 

      Schawinski, Kevin; Urry, C. Megan; Simmons, Brooke D.; Fortson, Lucy; Kaviraj, Sugata; Keel, William C.; Lintott, Chris J.; Masters, Karen L.; Nichol, Robert C.; Sarzi, Marc; Skibba, Ramin; Treister, Ezequiel; Willett, Kyle W.; Wong, O. Ivy; Yi, Sukyoung K. (2014-05-01)
      We use SDSS+GALEX+Galaxy Zoo data to study the quenching of star formation in lowredshift galaxies. We show that the green valley between the blue cloud of star-forming galaxies and the red sequence of quiescent galaxies ...

    • Radio galaxy zoo EMU: towards a semantic radio galaxy morphology taxonomy 

      Bowles, Micah; Tang, Hongming; Vardoulaki, Eleni; Alexander, Emma L.; Luo, Yan; Rudnick, Lawrence; Walmsley, Mike; Porter, Fiona; Scaife, Anna M.~M.; Slijepcevic, Inigo Val; Adams, Elizabeth A.~K.; Drabent, Alexander; Dugdale, Thomas; Gürkan, Gülay; Hopkins, Andrew M.; Jimenez-Andrade, Eric F.; Leahy, Denis A.; Norris, Ray P.; Rahman, Syed Faisal ur; Ouyang, Xichang; Segal, Gary; Shabala, Stanislav S.; Wong, O. Ivy (2023-04-11)
      We present a novel natural language processing (NLP) approach to deriving plain English descriptors for science cases otherwise restricted by obfuscating technical terminology. We address the limitations of common radio ...
