Query: Low-Mass X-ray Binaries and Globular Clusters Streamers and Arcs in
  NGC4278   We report significant inhomogeneities in the projected two-dimensional (2D)
spatial distributions of Low-Mass X-ray Binaries (LMXBs) and Globular Clusters
(GCs) of the intermediate mass elliptical galaxy NGC4278. In the inner region
of NGC4278, a significant arc-like excess of LMXBs extending south of the
center at ~50" in the western side of the galaxy can be associated to a similar
over-density of the spatial distribution of red GCs from~Brassington et al.
(2009). Using a recent catalog of GCs produced by Usher et al.(2013) and
covering the whole field of the NGC4278 galaxy, we have discovered two other
significant density structures outside the D25 isophote to the W and E of the
center of NGC4278, associated to an over-density and an under-density
respectively. We discuss the nature of these structures in the context of the
similar spatial inhomogeneities discovered in the LMXBs and GCs populations of
NGC4649 and NGC4261, respectively. These features suggest streamers from
disrupted and accreted dwarf companions.
