Hi Everyone,
My name is Carie and I'm the student Kevin Schawinski found at Yale to look at the peas. I've created this forum thread called, 'Peas Project' to collect these interesting galaxies. I'd greatly appreciate your help in collecting them. Please post to this new thread any objects that you find that meet the following criteria:
We're looking for galaxies that are very
green,
compact and if you look at the spectrum they have an big bright
OIII line. It's this OIII line in the
r-band that makes them look so green, so they should be at a redshift z > 0.15 and z < 0.45.
Here are some images of peas:
Here are some examples of what we're
not looking for:
http://cas.sdss.org/astro/en/tools/explore/obj.asp?id=587739303144325286The bright big QSO, looks like a pea because its green and compact, but if you click on the spectrum, you'll see it has a redshift z=4.2 and you'll see a large Ly_alpha line and not a large OIII line in the center.
Another example of something we're not looking for is a star like
http://cas.sdss.org/astro/en/tools/explore/obj.asp?id=587738409784311877. Its small and green, but there is no large OIII line in its spectrum.
We're not looking for all OIII objects, some like this one show OIII lines in their spectrum but are not compact and green.
Thank you so much for your help!
If there are any questions, go ahead and post them here
We'll be sure to let you know how the project progresses.
