Quantum gravity phenomenology at the dawn of the multi-messenger era—A review

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 various 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 which 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, prepared within the COST Action CA18108 “Quantum gravity phenomenology in the multi-messenger approach”, 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.publishedVersio

Groundwater Transport of Sulphates in the Estonian Oil Shale Mining Area

The development of Estonian power engineering onthe basis of oil shale has caused several changes in theenvironment. One phenomena which accompanies oil shalemining is heightened content of sulphates in groundwater andsurface water.The aim of this research is to give an overview of groundwaterand surface water transport of sulphates in the Estonian oil shale mining area and find out the regularity of its distribution during the time. As is known the aquifer containing the exploitable oil shale seam is influenced by mining activities the most, but also the quality of upper and lower aquifers can change. It is very important to clear up the vertical distribution of sulphates indifferent water-bearing horizons.The phosphorite mining area which finished its activity in 1991is also included in the research. The aim is to clear up to whatextent environmental conditions have become better and draw conclusions on the ground of old closed mines for working mines for getting to know how much time it will take for self-cleaning of the environment
