The magnetic field in the Small Magellanic Cloud and in the Magellanic Bridge

doi: 10.6062/jcis.2012.03.03.0062


A. Lobo Gomes et. al.


The Small Magellanic Cloud (SMC) and the Large Magellanic Cloud (LMC) are irregular galaxies orbiting the Milky Way. It is be lieved that the Magellanic Bridge, a structure linking SMC and LMC, was formed due to the interaction between the Clouds. The aim of this work is to study the magnetic field structure at the Northeast and the Wing sections of the SMC and at the Magellanic Bridge. For this purpose we have used optical polarimetric data and constructed a polarization map in order to trace the sky-projected magnetic field component. Furthermore, we are using MHD simulations to investigate the role of the magnetic field on the interaction of these galaxies and how it may have influenced the formation of the Magellanic Bridge and preliminary results of these numerical studies are also shown.
