Description
We present UBVRI imaging polarimetry of NGC 2100 and its surrounding
environment, which comprise a part of the LMC 2 supershell. The
morphology of the observed position angle distribution provides a tracer
of the projected magnetic field in this environment. Our polarization
maps detail regions exhibiting similarly aligned polarization position
angles, as well as more complex position angle patterns. We observe
regions of coherent fields on spatial scales of 42×24 to
104×83 pc, and infer projected field strengths of ~14-30 μG. We
propose that the superposition of global outflows from the LMC 2
environment, as well as outflows created within NGC 2100, produce the
unique field geometry in the region.
