An eye?

  • dcardani by dcardani

    This one is really interesting. It looks like the color of a smooth galaxy, but it looks like there are some features in it. Would this one count as "disturbed" or "irregular?"

    Yes, it does look like an eye. I did a quuck search, and there are more "eyes" that have been posted. eg. http://talk.galaxyzoo.org/#/subjects/AGZ0002884

    This simulated galaxy doesn't look either disturbed, or irregular. I would think it is simulated to be a distant spiral, we can't really see the spiral arms, but we can see the starforming ring around the nucleus.

    Galaxy Zoo scientists are studying galaxy formation. Here is a recent paper.

This implies a lack of significant mergers, ....This paper uses morphological classifications from the Galaxy Zoo1 project (Lintott et al. 2008, 2011) to construct a sample of bulgeless galaxies that host actively growing black holes. Selecting galaxies that lack classical bulges (as opposed to galaxies with a more varied history of both secular and merger-driven evolution) enables the isolated study of black hole growth in the absence of mergers...None of the galaxies in the sample show evidence of tidal features at the SDSS depth,
