Update regarding local discovery of Voorwerp
Dear all, here is a scientific update regarding the "Voorwerp" associated with IC 223, which I discovered recently.
(see also, the Deep Space imaging forum)
Dr William Keel, an AGN specialist and a member of the Galaxyzoo professional scientists' team, recently wrote this to me regarding the Voorwerp that I discovered:
"
I'm writing something up on this to pass around for the next Galaxy Zoo team telecon tomorrow. Will forward PDF with pictures on IC 223 when I paste it together.
Quick summary - the blob near IC 223 is not a strong emission line object in the optical, not appearing in either [O III] or H-alpha images. I do see it in a broadband V image (but not R), quite faintly, which would make sense for a young stellar population - but one somehow without much ionized gas, which is a curious state. I haven't yet worked out just how blue it has to be from V to FUV bands. "
Sincerely,
Robert Lang
