DESCRIPTION:The moduli space of smooth curves admits a universal Jacobian\
 , which is a smooth and proper group stack. If we want to extend the Jacob
 ian to the boundary of the moduli of stable curves\, these properties cann
 ot simultaneously persist. Many nice models exist\, sacrificing one proper
 ty to obtain the others. We will talk about two natural models\, the Neron
  model and the logarithmic Jacobian\, and explain how they are related.
