| Postdoc position at LERMA-LPENS on the statistical charaterization of the 21-cm signal from the Epoch of Reionization | Closing date: 2022-06-31
Contact: Benoit Semelin |
| The LERMA at Observatoire de Paris and the astrophysics group at LPENS are seeking candidates for a post-doctoral position funded by the ?Initiative Physique des Infinis? at Sorbonne Université on the development of novel statistical characterizations of the 21-cm signal from the Cosmic Dawn (CD) and Epoch of reionization (EoR). | | ▸ more | Context and project:
The LERMA at Observatoire de Paris and the astrophysics group at LPENS are seeking candidates for a post-doctoral position funded by the ?Initiative Physique des Infinis? at Sorbonne Université on the development of novel statistical characterizations of the 21-cm signal from the Cosmic Dawn (CD) and Epoch of reionization (EoR).
The team at LERMA has a strong expertise in the numerical modelling of the 21-cm signal from the CD-EoR while the team at LPENS has been developing novel statistical techniques based on Scattering Transforms for several years and applied them to astrophysical problems. Both teams are members of the Cosmic Dawn Key project on the NenuFAR radio-interferometer (https://nenufar.obs-nancay.fr).
The goal of the project is to explore the uses of the various flavors of scattering transforms to characterize the 21-cm signal, including non-gaussianity. Such novel summary statistics have potential in multiple applications such as in the foregrounds-signal separation or as a metric in the inference of the signal?s underlying model parameters. An application to the CD-EoR data from NenuFAR is intented.
Profile of the candidates:
The candidate will either be a cosmologist with expertise in statistical inference methods and some familiarity with the 21-cm signal science, or a data scientist with preferably previous experience in applying data science methods to astronomical data. He/she will play a federating role between the two teams.
Practical considerations:
The appointment is for 2 years with a possible extension to 3 years. The offer includes French social security benefits and funding for travel.
Applicants should submit a CV (max. 2 pages), a letter in intent, publication list, and two letters of recommendation. Applications should be sent via email to benoit.semelin @ obspm.fr and francois.boulanger @ phys.ens.fr . Applications will be accepted until the position is filled. The contract will have to start no later than 22 Dec 2022.
