Analysis of the first data of CTA telescopes

Ambito della ricerca

Astronomia e Astrofisica


CTA (Cherenkov Telescope Array) is a worldwide project to construct the next generation ground based very high energy gamma ray instrument [1]-[2]. CTA will use more than hundred Imaging Air Cherenkov Telescopes of three different sizes (mirror diameter of 4 m, 12 m and 23 m) deployed on two sites, one on each hemisphere (La Palma on the Canary Islands and Paranal in Chile). The CTA unconventional capabilities will address some of the most intriguing questions of astrophysics such as the origin of very high energy galactic cosmic rays. The observatory construction is foreseen in 2021-2025 but the first large size telescope (LST1) is already installed and in preproduction phase in La Palma. The first medium size telescope (MST1) is foreseen to be installed in La Palma at the beginning of 2021.

The CPPM-Marseille group is actively participating to the commissioning of the LST1 and to the preparation of the camera of MST1 (NectarCAM). The internship will concern the preparation of the commissioning phase for MST1 including data-monte carlo comparison of calibration data of NectarCAM taken in the laboratory and the analysis of the first data on sky. The student will also have the possibility to analyse the first data of LST1 including science verification data (i.e. observation of known gamma sources such as the Crab Nebula).
