Have you all seen the beautiful simulations created by Merger Zoo volunteers?

JeanTate Has just written this great OOTD Wednesday, 4th April, 2012: Wanted! More Volunteers for the Merger Wars featuring  ARP 107

So here is one of the simulations of ARP 107 that was chosen for the gallery 



It would have been lovely to know who’s simulation this was to credit them. Along with all the other beauties in the gallery.

So here’s a big Well Done Everyone who took part. 

It really is worth spending just a little bit of time clicking these galaxy images. Find them here



As Jean says in her OOTD there is still work to be done. Please read the blog The Finale of Merger Zoo

I copied below post from the another thread, because I think, that it should be also here.:

I read today the blog "The Finale of Merger Zoo; 27 March 2012 by John" and I've taken a look at the 54 thumbnails.
I don't understand if it is only a "zooites" sample or the base of more detailed study by the team.

I have some doubts on few pairs which can't be interacting at hundreds of megaparsecs apart, and i suggest to carefully estimate the distance between the two (or three) nuclei of the pair in interaction.
example
Pair
objid_in_pair                ra          dec                  z            neighbor_in _pair          n_ra              n_dec     n_z      sep (arcmin)  dist Mpc
588017604696408195 221.32866 38.805889 0.059753 588017604696408114 221.34691 38.781006 0.032244 1.72 203.2 

(...)

588017604696408195 is NGC 5753 (and the other one is NGC 5755)!
You missed, that in NED there is given a different redshift than in SDSS and an essential note: "SDSS has z = 0.059750 +- 0.000167" !
NED cites z=0.032099.  (It has nearly same redshift as the other galaxy and thus they might interact.)
So the redshift or spectrum in SDSS (DR7/DR8) seems to be wrong! (I have no clue, why the redshift in SDSS is different than in NED!) 
On the other hand, I wonder, if the disturbance of NGC 5755 is really caused by NGC 5753 or if NGC 5755 is actually itsself a GPair (at the spectrum target in SDSS there seems to be another galaxy: 588017604696408114).
Simbad says:
NGC 5753 -- Galaxy in Pair of Galaxies
NGC 5755 -- Interacting Galaxies

I copied my following post from an OOTD about ARP 274.:

Warning: this topic has not been posted in for at least 120 days.
This OOTD is from April 2009!
I noticed, that curiously it had been selected for the Merger Zoo! It was target on August 30, 2010.
I wonder, why it was selected, though it isn't clear, if it is an overlap or a merger!
