Summary
The goal of the internship is to develop the pipeline to produce the weak lensing selected cluster catalogue from the Euclid data with minimal contamination. The pipeline will rely on the algorithms that have been preselected by Euclid Science Working Groups.
Full description
Clusters of galaxies are the largest and most massive collapsed structures in the Universe.
Upcoming full-sky weak lensing surveys such as Euclid will offer for the first time the possibility to detect galaxy clusters based on their lensing signal i.e. directly on their total mass.
The goal of the project is to develop the pipeline to build a sample of galaxy clusters detected by weak lensing from Euclid data with minimal contamination. This catalogue will be used to derive new constraints on galaxy cluster abundances.
The objectives of the intership are the following:
1- Implement the cluster detection algorithms preselected by science working groups into an environment such as gitlab.
2- Combines the methods to maximise the purity and completeness of the sample
The candidate should be a Master/Engineer student in informatics. Experience with python/C++ coding would be advantageous.
The intership will take place in the DEDIP department of CEA Saclay. Supervision will be jointly conducted by Sandrine Pires and Nicolas Dagoneau.
