euraxess logohr logoApplications are invited for a 2 year Postdoctoral position to work with Dr. Astrid Lamberts and her group on gravitational wave astrophysics (French ANR Research grant COSMERGE) at- the Observatoire de la Côte d'Azur in Nice, France. The project will specifically focus on the origin (formation channels, host galaxies, epoch of star formation) of binary black hole

The project includes any of the following aspects :

  • massive binary evolution, including binary population synthesis methods and/or star cluster dynamics
  • cosmological star formation and cosmological simulations
  • GW signal modeling and Bayesian analysis

The successful candidate should have a Ph.D. in Astrophysics or GW physics. Proficiency in one of the topics above is recommended but experience in GW astrophysics is not required. Candidates with experience in Bayesian analysis are strongly encouraged to apply.

By Nov, 4th, enthusiastic candidates should send :

  1. a CV including a publication list (4p max),
  2. a statement of research interests (2p max),
  3. arrange for three letters of reference to be provided separately

Send all materials to using “COSMERGE postdoc” in the email header.

The preferred start date is March-April 2023 (negotiable).


The postdoctoral researcher will be working at the Observatoire de la Cote d'Azur, which hosts the Laboratoire Lagrange (astrophysics) and the Laboratoire Artémis (experimental physics for GW detection ). The primary affiliation of the postdoctoral researcher will depend on his/her research interests. The postdoctoral
researcher will be a member of the Virgo collaboration.

Nice is a beautiful city along the Mediterranean Sea (French Riviera) at the foot of the Alps. The Observatory is located on a hilltop above the city with impressive views on all sides.

Included Benefits :

The salary is set by national guidelines and is commensurate with experience. Included: National medical insurance, maternity/paternity leaves, family supplement for
children, participation to public transport fees, pension contributions. School is free in France for children above 3.

euraxess logohr logoThe Laboratoire Lagrange invites applications for a short-term postdoctoral fellowship in plasma physics, to work in the group "Turbulence fluide et plasma", under the supervision of Thierry Passot and Emanuele Tassi. The appointment is for four and a half months.

The successful applicant is expected to carry out original research in the area of theory and numerical simulations of gyrofluid models in the context of magnetic reconnection in collisionless space plasmas. In particular, a gyrofluid model is expected to be applied in order to investigate the destabilization of current sheets in collisionless plasmas, at scales much shorter than the ion scales. A 3D fully parallelized spectral code will be provided, in which it will be easy to implement the model equations.


Experience in numerical simulations of magnetic reconnection by means of gyrofluid models

Knowledge of the theory of magnetic reconnection in collisionless plasmas

Required experience

1 to 4 years

Applicants should have, or expect to obtain in the next months, a PhD in Physics or related discipline.

Knowledge of English and/or French is essential.


The gross monthly salary, fixed by the CNRS standards, is about 2833 €.


Applicants should send their curriculum vitae and a statement of research interests to the attention of Emanuele Tassi at or Thierry Passot at They should also arrange for one letter of recommendation to be sent to the same address.

Starting date

The starting date for the appointment is flexible but preferably corresponding to February 1st 2023. The closing date for applications is 21st October 2022.

Included Benefits

The fellowship includes health insurance and retirement plan.

The successful applicant will have access to the SIGGAM cluster, hosted at the Nice Observatory and to the French supercomputers of GENCI.
