Possible Voorwerps

Hi, I found multiple voorwerp candidates, here are some of them:

I don’t see voorwerpjes in any of these images

No #voorwerp in these images.

The third one looks like a tidal debris trail. The blob above the galaxy looks like it is part of the same arc that continues down below the galaxy.

thanks for the replies, what about this:

the blue object looks like a voorwerp to me.

Looks like a starforming region. There is LOTS of blue out there in the universe. You need to be looking for more vibrant shades.

How about these mergers at 234.7718, 42.9378?:

Still just star formation

Hi Ernest

A voorwerp shines with very narrow emission lines, so is essentially monochromatic. It will be detected with just one of the three filters they use on the telescope to produce the final colour images. So as Tom has said, you need to look for a very vivid colour. Since the light is only in a very narrow band of the spectrum unlike starlight, a voorwerp will probably be quite dim by comparison with the starlight from the galaxy that creates it. The very bright blue areas in the images from the galaxies you have posted here are star-forming regions where the new stars shine brighter than the older yellowish stars in the rest of the galaxy. The more you look around the more of those areas you will find, as they are very common, unlike voorwerps!

I appreciate your explanation, thanks!

Hi,
RA,Dec = 317.8816, -9.5382

ra=18.3070&dec=-15.4845

RA,Dec = 208.6618, 20.7178

(all the host galaxies are agn/seyfert)
Thoughts?

First one could be, but without higher resolution, it’s not really possible to tell.

Second one I suspect is starforming.

Third one looks like a separate starforming galaxy.

Hi @tombickle what do you think about this blue object at ra=167.6988&dec=28.2783?

Looks like an unrelated spiral galaxy in same line of sight as the bright eliptical
