Radio Galaxy Zoo and SDSS

    Radio Galaxy Zoo reveals the relativisitic jets of an elliptical galaxy. It all looks so exciting over there in Radio Zoo.

    Here is the radio and infrared data from Radio Zoo.

    Thanks Budgieye.

    There is, indeed, a lot of very exciting stuff over in RGZ.

    Recently super-zooite Dolorous Edd wrote about his discovery of (yet another) giant (2MASX J09470799-1338276 - A triple with rather impressive LAS); these are double (radio) lobe structures which are larger than ~1 megaparsec from end to end. While the host (the galaxy from which the double lobes were emitted) doesn't have a known redshift - and as it's outside the SDSS footprint, we don't even have a photometric redshift estimate - this particular giant is bigger than the Moon, in angular size! 😮

    Here's his overlay image:

    The host itself seems strange; hosts of giants are invariable (giant) elliptical galaxies, yet this one has DSS2 and WISE colors that seem quite atypical. And its morphology, in the DSS2 B band, is quite unlike that of any elliptical any GZ zooite has likely seen.

    I hope to soon post an overlay image or two of my own creation.

    If you're tired of classifying SDSS galaxies, why not head on over to RGZ and try your hand at classifying enigmatic radio structures? Who knows, you may find something that's even more stunning than Green Peas! 😃

    Thank you JeanTate for linking to this incredible sight of these huge black hole jets.
