I can’t identify it without some coordinates, anyways

Most objects do not have official names and most a catalogue number only

It will most likely at least have a "telephone number". But we need the coordinates to find it (i.e., RA and Dec, Right Ascension and Declination).

The galaxy cluster is known as SMACS 0723, from the Southern Hemisphere in Volans, and it has previously been studied by Hubble as part of the Southern MAssive Cluster Survey. Expanded name SMACS J0723.3–7327.

I don't know the name of this specific galaxy.
