This project focus on the study of extra-galactic transient sources with CTA. Beyond their interest as astrophysics sources, flaring active galaxy nuclei or gamma-ray burst are very promising probes for fundamental physics (Lorentz Invariance Violation, extragalactic background light…). The observation and study of GRBs is now of prime importance in the domain. The recent detection of several GRBs by H.E.S.S. and MAGIC opened a new window in VHE gamma-ray astronomy. Same applies for Virgo/LIGO whose detectors is now sending regular GW alerts from various kind of binary systems.
The first CTA large telescope is operational since the beginning of 2020 and will bring additional detection capabilities in the VHE gamma-ray domain. The project consists in participating in the commissioning and early science of the first LST, in the first CTA alert follow-up.


1) The first observations and alert follow-up with the first LST started mid of 2020. The candidate will take part of the commissioning of the telescope and assume a leading role in the analysis of the first data and the very first alert follow-up.

2) The CTA group at LAPP is deeply involved in the development of data analysis tools. The candidate can contribute to the test and optimisation of these tools in the frame of LST1 data.

3) CTA will re-act to alert sent by different instruments: X-ray and Gamma-ray telescopes, Neutrino telescopes and also Gravitational waves (GW) alerts from Virgo/Ligo. In particular, the candidate will integrate the CTA/Virgo working group at LAPP. The candidate can take the responsibility to maintain and upgrade the transient handler system of the LST.

4) A special attention will be brought to make sure that the work done can be integrated inside the open science frame.


Due to the multiple and ambitious aspects of this project, the successful applicant should already count on a solid background in high-energy astroparticle physics. An experience in VHE gamma-ray astronomy will be a plus. A solid experience in the operation of Cerenkov telescope is expected.

Attachment: CTA experiment
Experience: less than 2 years after the PhD

Work Context

LAPP is a combined CNRS and Université de Savoie Mont-Blanc unit. Close to 150 people are working at LAPP: researchers, professors, engineers and support staff, students and visiting scientists. The laboratory is very actively involved in several large international collaborations working on accelerators, neutrino detector and astroparticle experiments (Virgo, H.E.S.S. CTA and LSST). Involved in many R&D and construction programs for large research infrastructures, the laboratory's skills cover a large scope of domains involving innovative technologies in micro-electronics, complex mechanical structure design and optimization, grid computing and scientific software developments. The location of LAPP, 50 km from CERN, and the presence of the theory laboratory LAPTh in the same premises, make the LAPP campus a very attractive research place for scientists contributing to particle and astroparticle physics. LAPP hosts the MUST mid-range data storage and computing centre - widely open to distributed computing infrastructure supporting research and academic projects.
