Abstract (from CDS):

Using the photometric data from the Next Generation Fornax Survey, we find a significant radial alignment signal among the Fornax dwarf galaxies. For the first time, we report that the radial alignment signal of nucleated dwarfs is stronger than that of non-nucleated ones at the 2.4σ confidence level, and the dwarfs located in the outer region (R > Rvir/3; Rvir is the Fornax virial radius) show a slightly stronger radial alignment signal than those in the inner region (R < Rvir/3) at the 1.5σ level. We also find that the significance of the radial alignment signal is independent of the luminosities or sizes of the dwarfs.
