Statement on the situation in Ukraine
Our COST Action participants are deeply concerned and saddened by the ongoing invasion of Ukraine and the suffering of Ukrainian people. We are also very concerned about the persecution of Russian citizens who voice their opposition to the invasion.
Several action participants are actively seeking, each in their own independent way, funding opportunities that might be appealing for Ukrainian researchers, from senior levels to PhD students, and information on such funding opportunities, as well as contact data of Ukrainian researchers, will be included incrementally [*] on this document. We note that similar initiatives can be found at the sites https://www.scholarsatrisk.org/, https://scienceforukraine.eu/, https://euraxess.ec.europa.eu/ukraine and also at this site for CERN offers and here for positions at Perimeter Institute. INFN has announced some positions reserved for Ukrainian physicists, see this document.
Within our COST action the core group and the management committee are presently in an “alert mode” which should allow very expeditious evaluation of applications to join any of our work groups, and we encourage in particular applications from Ukraine and other countries at war.
Members of our work groups, if they are from a COST-funding eligible country (in particular Ukraine is COST-funding eligible), can apply for COST funding of short research visits (our “STSM” program). A call for proposals of short visits is presently open and we encourage in particular applications from Ukraine and other COST-funding-eligible countries at war.
QUANTUM GRAVITY PHENOMENOLOGY IN THE MULTI-MESSENGER APPROACH
The exploration of the Universe has recently entered a new era thanks to the multi-messenger paradigm. The detection of cosmic particles (photons, neutrinos, cosmic rays), now joined by the birth of gravitational wave astronomy, gives us information about the different sources in the Universe and the properties of the intergalactic medium
The most energetic events allow us to test our physical theories at energy regimes which are not directly accessible in accelerators. This is in fact the target of quantum gravity phenomenology, a quite recent field of physics that tries to set phenomenological models that may incorporate some of the effects of the Planck scale, thus providing a bottom-up approach to the largely studied quantum gravity problem.
The main objective of the proposed COST Action is to gather theoretical and experimental working groups from the relevant communities (with proper geographical, age and gender balance) to work in the prediction and possibility of detection of physical phenomena characteristic from quantum gravity theories. This cooperation is necessary to address this challenge properly, which may result in extraordinary advancements in fundamental physics. A second objective will be the formation of a generation of scientists that will be competent in the interdisciplinary expertise that is needed in the effective search of quantum gravity footprints in the production, propagation and detection of these cosmic messengers. Whatever the outcomes of this search may be, it will certainly have an important impact on science through a better understanding of the Universe and its fundamental laws.
