Biography
Mathieu Lamoureux is currently an FNRS postdoctoral researcher at UCLouvain (Belgium). He obtained his PhD at CEA Paris Saclay in 2018 on the search for hypothetical heavy neutrinos with the T2K experiment. In 2019, he was awarded a MSCA-COFUND fellowship at INFN Padova (Italy) and switched his focus towards neutrino astronomy. He also performed during a secondment period at UParis-Cité (France) in 2021. He has been working on the Super-Kamiokande and ANTARES experiments, with a focus on joint sources of neutrinos and gravitational waves and on neutrino emission from the Milky Way. At UCLouvain since 2022, he has been actively involved in the KM3NeT and IceCube Collaborations, pursuing the study of astrophysical neutrinos and their connections in the multimessenger picture.
Research statement
Since 2019, I have been focusing on the search for astrophysical neutrino sources, using different approaches to maximise the opportunities to unveil these sources.
- search for common sources of neutrinos and gravitational waves, e.g., compact binary mergers, exploiting temporal and spatial coincidence of the signal
- real-time strategies, using neutrinos to investigate transient sources reported in GCN, and sharing neutrino alerts with the community within a few minutes
- connections between neutrinos, gamma rays, and cosmic rays, notably to explain galactic emission and ultra-high-energy components
News and responsibilities
- Coordinator of the KM3NeT astronomy working group
- Technical coordinator of ACME (EU INFRA-SERV-01 project)
- Member of the KM3NeT Open Science committee
- Member of the scientific organising committee for the Third KM3NeT Town Hall meeting
- Member of the CP3 seminar organisation team.
- Publication of the "Observation of an ultra-high-energy cosmic neutrino with KM3NeT" in Nature (one of main analysers) + several companion articles (notably "The ultra-high-energy event KM3-230213A within the global neutrino landscape" as corresponding author)
- Organisation and co-organisation of IceCube masterclases (since 2023) and Physics Project Days (few days internship for high school female students to fight gender bias)
- Short stay in Harvard University to work together with Department of Physics colleagues and a seminar

Multi-messenger studies of astrophysical sources
Giacomo Bruno, Eliot Genton, Karlijn Kruiswijk, Mathieu Lamoureux, Jeff Lazar, Jonathan Mauro, Emile Moyaux, Christoph Raab, Leonardo Ricca, Marco Scarnera, Per Arne Sevle Myhr, Matthias Vereecken, Gwenhaël Wilberts Dewasseige

This project aims at studying astrophysical phenomena combining different messengers, mainly neutrinos, electromagnetic and gravitational waves.
Neutrino physics and astrophysics
Neutrinos from astrophysical transient sources
Eliot Genton, Karlijn Kruiswijk, Mathieu Lamoureux, Jeff Lazar, Jonathan Mauro, Emile Moyaux, Christoph Raab, Leonardo Ricca, Marco Scarnera, Per Arne Sevle Myhr, Matthias Vereecken, Gwenhaël Wilberts Dewasseige

This project aims at optimising neutrino telescopes, especially the IceCube Neutrino Observatory and KM3NeT, to detect GeV and sub-GeV astrophysical neutrinos. The instruments are then used to search for low-energy neutrinos from transient sources, such as solar flares, compact binary mergers, or gamma-ray bursts.
