The First Volunteer-inspired Galaxy Zoo Paper is Submitted!



 At long last the ‘Peas’ have been submitted to MNRAS (The Monthly  Notices of the  Royal Astronomical Society,).  The ‘Peas’ were  discovered by users right here in  Galaxy Zoo who noticed a strange  class of small green galaxies at redshifts near z=0.2. A dedicated  group of volunteered collected a sample of these galaxies.  Then Kevin Schawinski found an astronomer (Carie [me :)]) to pull them together  and look at them in detail.


We finally met at AAS (the American Astronomical Society) meeting this  January at the Long Beach California convention center.  Chris  Lintott, Jordan Raddick, and Daniel Thomas and I sat down and  discussed the paper draft.  In the ensuing 3 months, I’ve been working  hard at writing up all of our results with the help of all of the co-authors.  The peer review process can take a while, but as the publication process goes forward we’ll  keep you up to date.

Coming Soon: a new blog-post where will lay out the details of what  makes the Peas so exciting.

    Wonderful news!

  2. Pat says :

    Thanks Carie. 🙂 Well done again to all the Zooites that have contributed to this paper and project. 🙂 And Carie for all your hard work too. 🙂

  3. rick says :

    Very good news indeed! Thanks Carrie for your work.

  4. hjMizzou62 says :

    Very interesting, I didn’t have any of these “Peas” in the galaxies I classified.

    Thanks for sharing!

  5. Rod Guice says :

    Oustanding news! Congratulations to all on efforts to date and good luck on the peer review process! I saw the “Green Peas” string in the Forum, and will spend some time going through it.

  6. Hanny says :

    Yay! 😀 Thanks Carie! 😉

    Hey, this looks awesome. Will there be a submission to arXiv any time soon? I’d love to see your conclusions. Great stuff!

    Cheers, Ian

  11. Thomas J says :

    Great work Carie and the team 🙂

    Hi Carie
    Good news!
    Hope the peas (I mean peer) review process goes well.
    I can’t wait to read a summery.
    It was nice to put a face to the name.

  13. Kevin says :

    We generally don’t post papers to astro-ph (arxiv) before they have been accepted, or at least have gone through the initial review.

  14. Jordan says :

    Hearty congratulations to all of you that worked on the peas project. The way in which everyone has worked together on the peas research is one of the very coolest things about Galaxy Zoo.

  15. Stan Barraclough says :

    Proves to me what can be achieved when even novices work together and the results are co-ordinated by a profesional. Facinating.

  16. Sérgio says :

    Great news! Good job for everyone!

  17. Mariod505 says :

    So all the GalaxyZoo users who were critical in the research for this paper get buried under the “et al” in Land et al. (2008)?? GalaxyZoo’s biggest problem is that it dumbs down the research aspect of what individual contributors do, that even they lose respect for the monkey work they are doing. People are more intelligent than this website gives them credit for… If you build an interface where people can do more intelligent research collaboratively, I think you’ll be blown away with the discoveries they make. A dozen astronomers can’t possibly coordinate the collective intelligence of the online community. Let go of the reins, and this community will learn to fly.

  18. Arthur says :

    Congrats to all of you! Well deserved for your initiatives and combined efforts. An inspiration to keep working in the Zoo.

  19. Mukund says :

    Great job. Thanks to the whole team!!

  20. Kevin says :


    The title page of every Galaxy Zoo paper includes a link to the poster where everyone participating in GZ1 who allowed their name to be published is listed. In the peas paper specifically, we do acknowledge the peas corps individually.

  21. Cliff Boer says :

    Well done to all of the team!

    I recommend that the interface allow for more detailed observations to be recorded:

    Would the data not serve you better if we were able to select from more specific alternatives when observing something unusual?

    Additionally please consider the options of ‘equal’, ‘can’t decide’, or ‘none of the above’ in some of the places where we are asked to make a choice.

  22. trees says :

    Yep, I agree. We should have a better chance in sending descriptions of ‘stuff’ which is often much more intriguing than the galaxy we evaluate.

    In fact, I’m pretty sure that I did see one or more of those ‘peas’ but there was no way I could determine that they were special.

  23. Dee says :

    Hey this is great news. I wish I knew what the interesting part about the Peas is…can’t wait for your next blog about it.

    I didn’t see this one in your pictures

    although you may not have put all of them in your blog.

  24. trees says :

    And, certainly a lot of blue peas.

  25. Anonymous says :

    Amazing stuff. Looking forward to learning more from you about these peas

    By the way,
    how do I point at (RA:DEC) GalZooimg_q4_a2_n7.jpg
