Hot on the heels of the acceptance of our initial paper looking at the environmental dependence of morphology and colour, here’s another one considering similar questions, but using a very different approach.

The first author is Ramin Skibba, a friend of the Galaxy Zoo team, who is an expert in a mysterious analysis tool called ‘mark correlation functions’. He’s calculated these using the Galaxy Zoo data and interpreted the results to help us understand how the morphology and colour of galaxies depend on their environment. This has confirmed many of the findings in our previous paper, and given us new insight into the processes responsible for transforming galaxies from blue to red and spiral to elliptical. Ramin will write a blog post, explaining his paper in more detail, soon.

The paper has just been submitted to our usual journal of choice, Monthly Notices of the Royal Astronomical Society. The submitted version will be available later in the week; we’ll post more then.

(For those counting, this is the 7th Galaxy Zoo paper to be submitted. So far, four have been accepted and we’re still working on the other two).
