The optical calibration system for the CTAO North Large Sized Telescope
In 2018, the first prototype of the optical calibration system was installed in the Large Sized Telescopes, LST-1 at the Observatorio del Roque de los Muchachos, ORM, in La Palma, Canary Islands. We have almost completed the construction of the three remaining ones that will be mounted by 2026 on LST-2-3-4. The main feature of this system is to ensure a stable and constant photon flux over time with the characteristics of a signal produced by Cherenkov light when a high-energy gamma ray crosses…

Dark matter and fundamental physics with the Cherenkov Telescope Array Observatory
The Cherenkov Telescope Array Observatory (CTAO) will be the next-generation major ground-based gamma-ray observatory. It will be made up of two large arrays of imaging atmospheric Cherenkov telescopes (IACTs), with one site in the Northern hemisphere (La Palma, Canary Islands) and one in the Southern (Paranal, Chile). CTAO aims to offer great improvement in energetic and angular resolution with respect to current IACT systems, spanning a photon energy range from 20 GeV to 300 TeV, as well as a…

Dynamical Systems Perspective for a Real-Time Response to a Marine Oil Spill
This paper discusses the combined use of tools from dynamical systems theory and remote sensing techniques and shows how they are effective instruments which may greatly contribute to the decision making protocols of the emergency services for the real-time management of oil spills. This work presents the successful interplay of these techniques for a recent situation, the sinking of the Oleg Naydenov fishing ship that took place in Spain, close to the Canary Islands, in April 2015.
