Colour asymmetry between galaxies with clockwise and counterclockwise
  handedness
  Recent studies have shown that SDSS galaxies with clockwise patterns are
photometrically different from galaxies with anti-clockwise patterns. The
purpose of this study is to identify possible differences between the colour of
galaxies with clockwise handedness and the colour of galaxies with
anti-clockwise handedness. A dataset of 162,514 SDSS galaxies was separated
into clockwise and counterclockwise galaxies, and the colours of spiral
galaxies with clockwise handedness were compared to the colour of spiral
galaxies with anti-clockwise handedness. The results show that the i-r colour
in clockwise galaxies in SDSS is significantly higher compared to
anti-clockwise SDSS galaxies. The colour difference is strongest between the
right ascension of 30$^o$ and 60$^o$, while the RA range of 180$^o$ to 210$^o$
shows a much smaller difference.
