Object name: NGC3583
Designation(s): NGC3583, NGC3577,
NGC 3583 is a barred spiral, SB(s)b, in Ursa Major about 110 million light-years from us. It would fit Arp's category for spiral galaxies with a high surface brightness companion on its arm. Sometimes the companion was a true companion but most of the time either we still don't know or it wasn't a true companion. This time however it is a true companion and he didn't include it. Both have about the same redshift indicating they are related. Most sources NED notes call it an E0 galaxy. I find that odd on two counts. First E0 should be spherical and it is distinctly oval. Also, most E0 galaxies are rather red this one is blue though when IR is added to the mix by the Sloan survey it turns white. Still the wrong color. While it doesn't appear to be interacting I can't help but wonder if its shape indicates interaction has occurred, likely in the distant past. Something has to have triggered strong star formation in the last billion years or so for it to have this blue tint. NGC 3583 was discovered by William Herschel on February 5, 1788. It is in the second H400 program.
