Objectives (shared with WG3, WG5 and WG6)

To analyze the current state of the art of the experimental astronomy of each type of cosmic messenger with respect to the Action’s challenge and identify opportunities for improving the analysis strategies which are currently being followed, in the light of the theoretical frameworks and considerations of WG1 and WG2. To provide WG1 and WG2 with the technical details related to the detection of each type of astrophysical messenger, which need to be considered for a correct phenomenological and theoretical interpretation of the experimental results. To develop new analysis strategies that combine the observations of gamma rays, cosmic rays, neutrinos and gravitational waves for the search of quantum gravity signatures in the framework of multi-messenger astronomy. These new strategies should be developed in close cooperation with WG1 and specially with WG2. Finally, these WGs will transfer the Action’s motivations, progress and results, to their respective communities of experimentalists to promote their interest on the Action’s challenge.


Work on the update of phenomenological models used in previous works concerning the use of astrophysical neutrinos to search for quantum gravity signatures; clarify the situation with respect to the cosmic neutrino spectrum in terms of its apparent ending at energies higher than ~PeV and of the presence of different components; clarify the   situation with respect to the flux of GZK neutrinos; evaluate how neutrinos could be included in other searches for quantum gravity effects through the use of other cosmic messengers; develop new strategies for the search of quantum gravity effects by combining the observations of multiple messengers.


  • Year 1: Review, improve and update the already existing searches for quantum gravity signatures through cosmic neutrinos.
  • Year 2: Refine constraints in LIV phenomenology taking into account the theoretical predictions and observed properties for high-energy neutrinos from astrophysical sources and other components in the neutrino spectrum, such as GZK neutrinos.
  • Year 3: Study with the other messenger working groups how to include neutrinos in their searches.
  • Year 4: Development of multi-messenger search strategies based on the phenomenological models developed by WG1 and WG2.

Joint WG3-WG4-WG5-WG6 deliverables and activities

  • Publicly available web page with results of LIV studies based on each cosmic messenger.
  • Optimal strategy and method for performing LIV studies (including future experiments and a multi-messenger approach).
  • Publications, and contributions to conferences.
  • Contributions to the communication and outreach activities.
  • Organization of regular video conferences
  • Organization of workshops for specific topics involving also WG1-2
