Paolo D’Avanzo is senior researcher at INAF-Brera Astronomical Observatory. His research activity focuses on the study of transient X-ray binary systems, gamma-ray bursts and their connection with gravitational wave (GW) events. He is a member of the Italian team of the Neil Gehrels Swift Observatory (Swift) and of the GRAWITA (Gravitational Wave Inaf Team) and ENGRAVE (Electromagnetic counterparts of gravitational wave sources at the Very Large Telescope) collaborations for electromagnetic follow-up of GW events.

Julie Epas is a research engineer at the French Laboratory APC: Astroparticle and Cosmology. After a Master’s degree at Université d’Auvergne, she worked in the private sector before joining the CNRS in 2021. She is in charge of the activities at APC laboratory which is a functional centre of the AstroParticle Physics European Consortium (APPEC), currently as General Secretary of APPEC. She contributed to organizing and managing the preparation of the proposal for the ACME project, of which she is project manager.

Damien Dornic is a research director CNRS working at CPPM (Marseille, France). He has a long experience in the high-energy neutrino astronomy with ANTARES and KM3NeT and on multi-messenger analyses involving neutrinos and gravitational waves. He is currently the deputy spokesperson of the KM3NeT Collaboration, a co-I of the SVOM mission and co-I of the COLIBRI and GRANDMA consortium and member of the SNEWS2.0 consortium.

Prof. Rob Beswick is an active researcher in extragalactic astrophysics at the University of Manchester. He is the Joint-Director of the UK’s SKA Regional Centre (UKSRC), a project spanning institutes across the UK as part of an exascale partnership delivering data and compute resources needed for the SKAO. He is also the Head of Science Operations for the UK’s e-MERLIN/VLBI National facility, based at JBO, and is responsible for the Science delivery of the UK’s National Radio Astronomy facility.

Zsolt Paragi is a radio astronomer working in the field of very long baseline interferometry (VLBI). He is the head of User Support group at the Joint Institute for VLBI ERIC (JIVE). His scientific interests range from multi-band/messenger studies of stellar transient sources to high-redshift active galactic nuclei. He pioneered using novel techniques like real-time correlation electronic VLBI (e-VLBI); detecting and localize fast radio bursts with VLBI, as well as imaging electromagnetic counterparts to sources of gravitational waves with the European VLBI Network (EVN). In recent years he has been the Chair of the EVN Program Committee. He is the vice-president of the IAU Commission B4 (Radio Astronomy).

Łukasz Wyrzykowski (pron. Woo-cash Vi-zhi-kov-ski) is a professor of astronomy at the University of Warsaw and NCBJ. He earned his PhD in 2005 and was a postdoc at Cambridge (2006–2015), where he contributed to the Gaia Photometric Science Alerts system. Since 2013, he has led BHTOM.space, a global telescope network for time-domain follow-up. He studies optical transients and black holes. Member of the OGLE, ePESSTO, and ENGRAVE projects.

Dr. Fabian Schüssler is a senior researcher at IRFU / CEA Paris-Saclay, specializing in high-energy astrophysics and multi-messenger astronomy. His work spans from cosmic rays to gamma-ray, neutrino and X-ray astronomy, with key contributions to major collaborations like the Pierre Auger Observatory, ANTARES, H.E.S.S., CTA, and SVOM. He leads the development of platforms like Astro-COLIBRI and Tilepy, enabling and facilitating real-time multi-messenger observations.

Natalie Webb works on multi-wavelength and multi-messenger observations of compact objects to understand their nature and the role they play in their environment. She leads the XMM-Newton SSC which provides the XMM-Newton X-ray catalogues and contributes to the software and pipeline used for reducing and analysing XMM-Newton data. She also leads the ground segment for Athena/X-IFU. She is the president of the Astronomy Working Group at the French Space Agency and president of the ESA astronomy archives users group.

Gwenhaël Wilberts Dewasseige is an astroparticle physicist, member of the IceCube and the KM3NeT collaborations. She is mainly focused on MeV-GeV neutrinos coming from transient events, such as solar flares, core-collapse supernovae, and compact binary mergers. Her work has three different directions: pushing the capabilty of instrument to lower the energy threshold to sub-GeV; carrying out searches for low-energy neutrinos with new strategies to cope with the significant background; converting obtained limits into constraints on physical parameters of the studied sources.
