Welcome Quantum gravity phenomenology in the multi-messenger approach wiki page


The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experimental data, that is obtained by the detection of the cosmic messengers (photons, neutrinos, cosmic rays, and gravitational waves) from numerous origins. They give us information about their sources in the universe and the properties of the intergalactic medium. Moreover, multi-messenger astronomy opens up the possibility to search for phenomenological signatures of quantum gravity. On the one hand, the most energetic events allow us to test our physical theories at energy regimes that are not directly accessible in accelerators; on the other hand, tiny effects in the propagation of very high energy particles could be amplified by cosmological distances. After decades of merely theoretical investigations, the possibility of obtaining phenomenological indications of Planck-scale effects is a revolutionary step in the quest for a quantum theory of gravity, but it requires cooperation between different communities of physicists (both theoretical and experimental). This review is aimed at promoting this cooperation by giving a state-of-the art account of the interdisciplinary expertise that is needed in the effective search of quantum gravity footprints in the production, propagation and detection of cosmic messengers.


In a reference table you can find experimental bounds on quantum gravity searches. The reference table contains results from all four cosmic messengers. Links to the used articles are listed below the table.

On this wiki page, you can also find the description of the effects used in quantum gravity searches and analysis methods used to obtain the bounds.

Some experimental results could not be fitted in one combined table. For that reason, each messenger has its own subpage which you can find under the Cosmic messengers tab. Under the same tab, you can find descriptions of astrophisical sources used in experimental searches.

The goal of this project is to create a knowledge hub for everyone who is interested in this subject to participate and collaborate together. If you register (click on Log in in right upper corner of the page and then select Register) you will be able to visit the Homepage for Registered users, where you will be able to test some of the features which will allow you to work collaboratively with others.
