NGC 55 Group - The Missing 12

Post #1by Gurren Lagann » 19.11.2020, 23:57

A generally neglected galaxy group with 18 member galaxies (half of which clash with the Local Group), this seems like a great, chill place (for worldbuilders) - not too far, not too close. Surely this place should be concretely known, right? Hahaha, not at all!
After 5 days of researching on 4 different places (SIMBAD, NED, VizieR, and HyperLEDA), some Excel shenanigans and GeoGebra 3D plotting, a Perl script, and even Mamajek's stellar relations table (don't ask), I present to you:

The NGC 55 Group
Where membership is hard to determine

Minor galaxies

Here is a rough 3D plot of the cluster in GeoGebra 5 (open to view the animation):

Galaxies are represented by points, while the possible subgroups are represented by red spheres.


Special thanks to LukeCEL and Fridger, for making the Perl script that converted HyperLEDA data to AxisAngle values whenever possible
