Objectives (SHARED WITH WG3, WG4 AND WG5)
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.
Tasks
WG6 will aim to further constrain possible deviations from the post-Newtonian description of binary inspiral, eventually down to the sub-percent level, by combining information from tens to hundreds
of GW sources. Continued GW dispersion measurements will lead to increasingly better bounds on local Lorentz invariance violations and on the mass of the graviton. However, qualitatively new tests of GR
and of the black hole nature of massive compact objects will become possible during the timespan of the Action. Anomalous tidal effects during the late inspiral of presumed binary black holes would be
indicative of “black hole mimickers”. For example, if dark matter consists of fermionic particles then they may form dense stars, which if present in a binary system would betray their nature by the presence of tides. Next, the remnant object resulting from the merger of two compact bodies will undergo “ringdown” as it asymptotes to a quiet state. The associated GW signal involves characteristic frequencies and timescales which for standard black holes should only depend on mass and spin, as a result of the black
hole no-hair theorem. Deviations from this would be tell-tale signs of a horizon modification, or of an entirely different kind of object having formed. Finally, prompted by Hawking’s information paradox, some have proposed macroscopic quantum modifications of black hole structure (“firewalls” and “fuzzballs”), which would lead to GW “echoes” being emitted after the ringdown signal has died down. Though the above is GW-focused, we note the value of a multi-messenger approach: for example,
should an electromagnetic counterpart be seen to a binary merger in the black hole mass range, then this will be a further indication of new physics, and it would help elucidate the nature of black hole mimickers.
Milestones
- Year 1: Computational optimization of analyses of binary merger dynamics, and of searches for anomalous GW propagation.
- Year 2: Development of concrete data analysis tools to search for anomalous tidal effects during inspiral, tests of the no-hair theorem, and GW echoes.
- Year 3: Formulation of a comprehensive multi-messenger framework to search for black hole mimickers.
- Year 4: Application of the resulting analysis tools to detections made with Advanced LIGO and Advanced Virgo at final design sensitivity.
