Objectives (shared with WG4, 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.
Set-up, maintain and regularly update a database of all existing results on LIV based on time of flight studies with gamma-rays; compare the methods and results of different studies; establish a common strategy and optimal method for analyzing data from different source classes [GRB, active galactic nuclei (AGN), pulsars] and different instruments (ground-based Cherenkov telescopes, satellite detectors), using the triggers from observations in other wavelengths and messengers, and taking into account both the status of already published proto-population studies (mostly with GRBs), and future population studies that will consider data from tens of objects and different experiments (IACTs, satellites) combined together; work on our understanding of the sources themselves in order to isolate source-intrinsic temporal effects, which will allow to put more stringent constraints on LIV; develop a standard to characterize atmospheric aerosols based on LIDAR (Light Detection and Ranging) and stellar extinction measurements, and provide the corresponding corrections to IACT data, based on tailored Monte Carlo simulations; devise strategy for observing more astrophysical phenomena suitable for LIV studies with pointing instruments (e.g. AGN flares observed with IACT); in cooperation with WG1-2, identify possible signatures in gamma-ray signals of other hypothetical phenomena (e.g. axion-like particles).
- Year 1: Set-up a database of all existing results on LIV based on gamma-rays and publish it on web page. Compare the results and methods used.
- Year 2: Optimization of strategies and methods for performing LIV studies based on gamma-rays, benefitting at best from AGN flare observation strategies conceived for astrophysical studies.
- Year 3: List of possible signatures in gamma-ray signals of other hypothetical phenomena and possible methods for detecting signatures.
- Year 4: Development of multi-messenger search strategies based on the phenomenological models developed by WG1 and WG2.
