Jahangiri, M. (author), Sberna, P. (author), Sammak, A. (author), Nihtianov, S. (author)A clear understanding of the spectral components of an irradiated beam, or captured optical emission, is essential to optimize an optical system and increase its performance. Logically, for this purpose a grating-based spectrometer could be the first choice. However, in the case of a wide range spectrum, and for radiation with one dominant...article 2023

van Dael, M. (author), Witvoet, G. (author), Swinkels, B. (author), Oomen, T. (author)Gravitational Wave (GW) detectors are state-of-the-art mechatronic systems that can measure spatial distortions in the order of 10"18 meters. Two GW detectors that are currently operational are LIGO and Virgo, both of which have already measured GWs, with the first one being measured in 2015 resulting from the collision of two black holes. These...conference paper 2022

Gozzini, S.R. (author)An anomalous flux of neutrinos produced in hypothetical annihilations or decays of dark matter inside a source would produce a signal observable with neutrino telescopes. As suggested by observations, a conspicuous amount of dark matter is believed to accumulate in the centre of our Galaxy, which is in neat visibility for the Mediterranean...conference paper 2021

le Breton, R. (author), van der Knaap, F.G.P. (author), Buis, E.J. (author)Large research infrastructures have opened new observational windows, allowing us to study the structure of matter up to the entire Universe. However, society hardly observes these developments through education and outreach activities. This induces a gap between frontier science and society that may create misconceptions about the content,...conference paper 2021
