  Prompted by the many controversial claims involving the NGC 1052 group,
including that it hosts two dark matter-free galaxies with overluminous and
monochromatic globular cluster (GC) systems, here we map out the large-scale
structure (LSS) of GCs over the entire group. To recover the LSS, we use
archival optical CFHT imaging data. We recover two GC density maps, one based
on universal photometric properties of GCs from simple stellar population
models, and one based on the properties of spectroscopically confirmed GCs in
DF2 and DF4 (the two dwarf galaxies with overluminous GC populations). Both
selection methods reveal overdensities around the massive galaxies in the
group, as well as around NGC 1052 itself, that are coincident with the
positions of previously identified stellar streams and tidal features. No
intragroup GCs are found connecting these structures to any of the dwarf
galaxies. We find, however, two other dwarfs in the group hosting GC systems.
These include RCP32 with 2 GCs with ages equivalent to the GCs around NGC 1052,
and DF9 with 3 GCs with ages similar to the GCs around DF2 and DF4. We conclude
that the GC distribution in the group does not strongly support any formation
scenario in particular. It favours, nonetheless, scenarios relying on
galaxy-galaxy interactions and on the coeval formation of GCs around the
DM-free dwarf galaxies. These may include the recently proposed bullet-dwarf
formation, as well as high-redshift tidal dwarf galaxy models.
