The hidden giant: discovery of an enormous Galactic dwarf satellite in Gaia DR2
We
report the discovery of a Milky-Way satellite in the constellation of
Antlia. The Antlia 2 dwarf galaxy is located behind the Galactic disc at
a latitude of $b\sim 11^{\circ}$ and spans 1.26 degrees, which
corresponds to $\sim2.9$ kpc at its distance of 130 kpc.
