Here are a few of mine

ID: AHZ2000ojt

ID: AHZ2001qgm

ID: AHZ20019zd


ID: AHZ40002yu


ID: AHZ10005zt
Not too sure about this one, as there are spiral features, and the blobs could just be star forming regions  ???

More intrested in the bottom galaxy, very blobby, but more likely to be star forming regions.

One of the theories surrounding these objects, as I understand it, is that they are star-forming clumps nucleating out of pre-existing clouds of gas and are the precursors of spirals, and possibly other types. I am never quite sure whether ones like Capella's  AHZ2001po3 are stages along the way, whether they are something different or what. Anybody any thoughts?

Hello  :)

Thought I'd post a link to Alice's Oxford notes here.

...and then you get ones like this....



AHZ2000yje    z= 1.111

is this one object which has fractured? or is it a group independently coalescing in some cloud? or could it be an optical alignment? Any of the above is interesting in its own right. They just fascinate me - sad as I am  ;D

Echo,

Thanks for posting these. I was just taking mental notes!

Wow   :o

I have no idea how I would begin to interpret that!
I don't see a central gavitational source, about which too 'congregate', but... it is fascinating that it is only in one quadrant.

Please include any IrS, XrayS, RadioS or QSOs from
NED's search list with your posts. Also mention the z.
Thank you, Happy hunting.


examples:
http://www.galaxyzoo.org/examine/AHZ2000ezh z1.498 (NED z0.660000  PHOT)
http://cas.sdss.org/dr6/en/tools/explore/obj.asp?ra=149.543730&dec=1.885870
NED has 226 objects out to .997 arcmin.  (no IXRQs)

http://www.galaxyzoo.org/examine/AHZ2000yje z1.11 (NED z1.19-2.49 PHOT)
NED has 189 objects out to .994 with 1 XrayS.

....and then two come along together!



AHZ2001ow1;   z=0.706

COSMOS reports three objects with 0.1 arcsec; no spectrum from closest match (COSMOS 0539084) - no surprise there then

As joinpep was saying spectra of any kind are always worth noting if they are out there.
