Polar ring galaxies thread

That first one is not a polar-ring but actually a voorwerp. You can see these blue features are not the rings of the polar-ring galaxy. Voorwerps are a different name for an extended emission-line region. It’s a Dutch translation of “object”

I knew the translation, was sure the first galaxy was a p-r though ~ cheers👍

A quick change to this thread: Please make sure these candidates are on the NPA atlas, based on others’ findings. If you found a polar-ring galaxy, consider checking the New Polar-ring Atlas (NPA) before you post your candidate.

Cheers,
-Chris S.

Found a new polar ring galaxy. I have cross-checked it with NPA; it’s not there. In the R-band image, if you scale it, you can see more clearly an orthogonal structure in the galaxy.

I think that’s a slight p-r look

Found a polar-ring galaxy right next to an already existing NPA galaxy

Okay. I have finally updated the NPA successfully, but the overlay will be delayed until May 10th because of CSV file issues uploading.
@dstn - Please fix the issue so I can upload the May catalog.

cheers

I don’t know what you’re talking about. You’re having trouble uploading your CSV file?

I tried example cat and it works for me?

Thank you William and Dustin for your responses. I am investigating the issue.
