DESCRIPTION: ABSTRACT: Polarimetry of the light provides unique insights i
 nto multiple astrophysical processes in the Universe that cannot be inferr
 ed from usual intensity observations. In this talk we review the importanc
 e of optical polarimetry in three different astrophysical systems: i) acti
 ve galactic nuclei: supermassive black holes surrounded by accretion disks
  at the center of major galaxies\, ii) kilonovae: the optical emission of 
 compact neutron star mergers that are preceded by gravitational wave emiss
 ion\, and iii) supernovae: the explosive end of massive stars or of white 
 dwarfs in binary systems. We discuss how different theoretical models of t
 he progenitor and physical processes of these systems shape the predicted 
 optical linear polarimetry and compare them to current observations. We pa
 y particular attention to the systematic bias of interstellar polarization
  from dust in the line of sight.
