COST Action CA18108 (https://qg-mm.unizar.es/) is an initiative funded by the COST Association (https://www.cost.eu/). It is aimed at enabling researchers from different communities of quantum gravity, theoreticians, phenomenologists and gamma-ray, neutrino, cosmic-ray and gravitational-wave experimentalists, to learn about each other's work and cooperate on the goal of developing new strategies for testing candidate quantum gravity theories using multi-messenger high-energy astrophysical observations.  

This is the fourth Annual Conference and the final event of the CA18108.
Attendance will be preferably in person in Rijeka.

Important dates:

April 30 May 14: Early Registration deadline / Deadline for abstract submission

May 26: Confirmation of financial support / Confirmation of talk selection

May 31: Late Registration deadline (financial support might not be available at this point, depending on the number of early registrants)

July 10: Arrival day

July 12: Conference Dinner

July 13: Outreach event

July 15: Departure day

Financial support:

Participation for COST Action participants can be funded by COST. A first round of COST invitations will be sent in late May.
