Galaxy clustering in the VVV Near-IR Galaxy Catalogue
  Mapping galaxies at low Galactic latitudes and determining their clustering
status are fundamental steps in defining the large-scale structure in the
nearby Universe. The VVV Near-IR Galaxy Catalogue (VVV NIRGC) allows us to
explore this region in great detail. Our goal is to identify galaxy
overdensities and characterize galaxy clustering in the Zone of Avoidance. We
use different clustering algorithms to identify galaxy overdensities: the
Voronoi tessellations, the Minimum Spanning Tree and the Ordering Points To
Identify the Clustering Structure. We studied the membership, isolation,
compactness, and flux limits to identify compact groups of galaxies. Each
method identified a variety of galaxy systems across the Galactic Plane that
are publicly available.We also explore the probability that these systems are
formed by concordant galaxies using mock catalogues. Nineteen galaxy systems
were identified in all of the four methods. They have the highest probability
to be real overdensities. We stress the need for spectroscopic follow-up
observations to confirm and characterize these new structures.
