The Doctoral School depends from four University consortia:

• Paris Science et Lettres (PSL - Lead University).
• Sorbonne Université (SU).
• Université Sorbonne Paris-Cité (USPC).
• Université Paris-Saclay (UPS).

We work with most laboratories in Paris or around with astronomy astrophysics research.

The Doctoral School is directed by a board which includes the director, the four representative from the Universities participating in the doctoral school and the person in charge of the doctoral courses (see "Contacts" on the right).

Its political choices are discussed and decided by its council. 5 representatives from the PhDs students are members of the council.

PhD students are registered in one of the following Universities.

• Observatoire de Paris (OP).
• Ecole Normale Supérieure (ENS).
• Sorbonne Université (SU).
• Université Paris-Diderot (UPD).
• Université Paris Sud (UPSud).
• Université Versailles-St-Quentin en Yvelynes (UVSQ).
• Ecole Polytechnique (X).
