How Our Largest Dwarf Galaxy Keeps the Others In Line

The LMC is a massive dwarf companion to our Milky Way, with at least a tenth the mass of the Milky Way. It’s swinging around our galaxy for the first time on a trajectory that aligns with the Milky Way's plane of satellites. It seems unlikely that this alignment is a coincidence. New research led by Nico Garavito Camargo (Arizona Ph.D., 2021), Ekta Patel (Arizona Ph.D., 2019) and Associate Professor Gurtina Besla, have suggested that the LMC has inspired the observationally rare and seemingly mysterious properties of this polar structure.
