Galaxy Zoo: the dependence of morphology and colour on environment (2008)

Bamford, Steven P., Nichol, Robert C., Baldry, Ivan K., Land, Kate, Lintott, Chris J., Schawinski, Kevin, ...

We analyse the relationships between galaxy morphology, colour, environment and stellar mass using data for over 100,000 objects from Galaxy Zoo, the largest sample of visually classified...

Galaxy Zoo : Morphologies derived from visual inspection of galaxies from the Sloan Digital Sky Survey (2008)

Lintott, Chris J., Schawinski, Kevin, Slosar, Anze, Land, Kate, Bamford, Steven, Thomas, Daniel, ...

In order to understand the formation and subsequent evolution of galaxies one must first distinguish between the two main morphological classes of massive systems: spirals and early-type systems....

Galaxy Zoo: The large-scale spin statistics of spiral galaxies in the Sloan Digital Sky Survey (2008)

Land, Kate, Slosar, Anze, Lintott, Chris, Andreescu, Dan, Bamford, Steven, Murray, Phil, ...

We re-examine the evidence for a violation of large-scale statistical isotropy in the distribution of projected spin vectors of spiral galaxies. We have a sample of $\sim 37,000$ spiral galaxies from...
