[GA215] Review of optical polarisation measurements of MAGIC blazars
Since 2010, the MAGIC collaboration has been sustaining optical polarisation observational campaigns in support to its blazar observations and studies. Along the years, the correlation between features in the optical polarisation emission and the gamma-ray behaviour of a number of sources at energies above 100 GeV has revealed that the polarised emission is an important diagnostic of the physical state of blazar jets and that extreme variations in the polarisation emission mark correlated signatures of the behaviour of the sources at very-high-energies. In this contribution we will review the different works involving optical polarisation studies conducted by the MAGIC collaboration and discuss the most important, general conclusions taken from them.
