"The CFHTLS Deep Catalog of Interacting Galaxies I. Merger Rate Evolution to z=1.2"
Authors: Carrie R. Bridge, Raymond G. Carlberg, Mark Sullivan
(Submitted on 15 Jan 2010)
Quote
We developed a new classification scheme to identify major galaxy-galaxy mergers based on the presence of tidal tails and bridges. These morphological features are signposts of recent and ongoing merger activity. Through the visual classification of all galaxies, down to i_vega<22.2 (~27,000 galaxies) over 2 square degrees, we have compiled the CFHTLS Deep Catalog of Interacting Galaxies, with ~1600 merging galaxies.
Quote
TABLE 2
Classification Scheme for Interacting Galaxies

“Long Tidal Tails”: Tail Length > Diameter of Host
Galaxies with a long tidal tail:    1 tail   157
Galaxies with a long tidal tail:    2 tails 183
Galaxies with a long tidal tail: > 2 tails   36

Close Pair with bridge + long tail(s)       50

Galaxies w/ a DN + long tail(s)              62

Not sure where this fits into your above criteria Zutopian.  This is UGC 7064, a triple merger.  Previously posted in biggest cosmic trainwrecks.

remarkable, all we need now is a couple of spectra even if, visually, it is a tidal interaction.. 8)
