Job description:
PostDoc position for the development of the analysis pipeline for the CTA Observatory
The CPPM (Centre de Physique des Particules de Marseille) is a laboratory of the IN2P3 (Institut
National de Physique Nucléaire et de Physique des Particules) of the CNRS (Centre National de la
Recherche Scientifique), located on the campus of Luminy in Marseille (France). The activities of
CPPM are centered on particle physics, astroparticle physics and cosmology. CPPM offers a strong
environment in the field of astroparticle physics, being involved both in current (H.E.S.S., ANTARES) and
upcoming (CTA, KM3NeT) projects.
The gamma-ray astrophysics group of CPPM participates since several years to the Cherenkov Tele-
scope Array (CTA), a project to build the next generation ground-based very high energy gamma-ray
observatory. The group is responsible in CTA for the data acquisition software (Event Builder) of the
NectarCAM and LST-CAM cameras for the medium-sized and for the large-sized telescope, respectively.
It is also coordinating the offline camera calibration for the first LST telescope, presently in commission-
ing at the La Palma site, and Monte Carlo simulation activity in NectarCAM. Furthermore, the group
works in the preparatory studies for the research of galactic PeVatrons with CTA and is leading the ob-
servational proposal with the first LST telescope of the measurement of a promising PeVatron candi-
date.
The successful applicant will work on the reconstruction pipeline (dataPipe) of the Data Processing and
Preservation System (DPPS) of the CTA observatory. In particular, the work will be inscribed in the de-
velopment of the data workflow that spans from the reconstructed-air-shower data level (DL2) to the
science-ready data level (DL3). The focus will be first on the classification of the events into different
“event types” as a function of reconstruction quality and background rejection capability, then on the
development of all tools necessary for the production of “event type” dependent Instrument Response
Functions. She/he will also participate to the integration and testing activities of the pipeline, applied to
simulated data and commissioning real data. This activity will be performed in strong synergy with all
other dataPipe developments and in close collaboration with the other teams working in DPPS.
The development will be made in the context of the early science phase of CTA, giving the opportunity
to cover science subjects to be discussed with the candidate.
The candidates should hold a PhD in astroparticle or astrophysics with a strong motivation in algorithm
and software development. She/he should have knowledge in formal code release and documentation
and a good understanding of experimental data analysis. The software will be written in Python.
The position is available from mid 2024 for a period of 2 years + 1 year of renewal. The position will
remain open until filled. The candidate selection will start on April 1st 2024.
The application should be sent to Heide Costantini ([email protected]) and Franca Cassol (cas-
[email protected]) and should include:
• A letter of motivation;
• A curriculum vitae, a list of relevant publications;
• The names of at least two references and at least two letters of recommendation.
