What were you talking about ? Do you have an image of these blue caterpillars ?  :)

There are lots and lots of these "Blue Blobby Objects" (BBOs ??)  around. I thought at first that they were poor images, but realise now that they aren't. Anyone have any thoughts?

It's not entirely clear what they are but with the help of your Hubble Zoo classifications we will be able to study them better. The leading idea is that they are very gas-rich disk galaxies in the process of fragmenting. The gas turns to stars, so the individual clumps you see are clumps of intense star formation.

More disk, less clump, but might be relevant. I don't see it as an edge-on.

So OK, here are some of mine:



AHZ 2001h82  z = 2.09




AHZ 40001a8  z=0.225



AHZ 400002c9  z = 1.08



AHZ 400076m  z= 0.517



AHZ 40005fm  z = 0.69


Some of these, particularly AHZ 40002c9, are very like what Kevin was showing the other day, some less like. They seem to around at most z.

The more the better.
