    • Galaxy Zoo Green Peas: discovery of a class of compact extremely star-forming galaxies 

      Cardamone, C.; Schawinski, K.; Sarzi, M.; Bamford, S.; Bennert, N.; Urry, C.M.; Lintott, C.; Keel, W.; Parejko, J.; Nichol, R.C.; Thomas, D.; Andreescu, D.; Murray, P.; Raddick, M.J.; Slosar, A.; Szalay, A.; Vandenberg, J. (2009)
      We investigate a class of rapidly growing emission line galaxies, known as 'Green Peas', first noted by volunteers in the Galaxy Zoo project because of their peculiar bright green colour and small size, unresolved in Sloan ...

    • Galaxy Zoo: Hanny's Voorwerp, a quasar light echo? 

      Lintott, C.; Schawinski, K.; Keel, W.; Van Arkel, H.; Bennert, N.; Edmondson, E.; Thomas, D.; Smith, Daniel; Herbert, P.D.; Jarvis, M.J.; Virani, S.; Andreescu, D.; Bamford, S.; Land, K.; Murray, P.; Nichol, R.C.; Raddick, M.J.; Slosar, A.; Szalay, A.; Vandenberg, J. (2009)
      We report the discovery of an unusual object near the spiral galaxy IC 2497, discovered by visual inspection of the Sloan Digital Sky Survey (SDSS) as part of the Galaxy Zoo project. The object, known as Hanny's Voorwerp, ...

    • Galaxy Zoo: the fundamentally different co-evolution of supermassive black holes and their early- and late-type host galaxies 

      Schawinski, K.; Urry, C.M.; Virani, S.; Coppi, P.; Bamford, S.; Treister, E.; Lintott, C.; Sarzi, M.; Keel, W.; Kaviraj, S.; Cardamone, C.; Masters, K.L.; Ross, N.P.; Andreescu, D.; Murray, P.; Nichol, R.C.; Raddick, M.J.; Slosar, A.; Szalay, A.; Thomas, D.; Vandenberg, J. (2010)
      We use data from the Sloan Digital Sky Survey and visual classifications of morphology from the Galaxy Zoo project to study black hole growth in the nearby universe (z < 0.05) and to break down the active galactic nucleus ...
