PAFT26 – Quantum Frontiers in Gravity, March 29 – April 1 2026 in Vietri Sul Mare The main objective of the conference „PAFT26 – Quantum Frontiers in Gravity“ is to bring together theoretical physicists and phenomenologists who are experts in the complementary fields of classical and quantum gravity, modified gravity, and experimental aspects of gravity in quantum systems. The conference will give space to a constructive exchange of ideas and encourage new collaborations. Conference Website

IberiCos 2026, April 22-24 2026 at University of Granada The spirit of the meetings is to provide an open and inclusive forum for sharing ongoing research. Accordingly, IberiCOS 2026 will cover a wide range of topics, including primordial black holes, dark energy and dark matter, theoretical and observational cosmology, and gravitational waves. A key goal of the meeting is to foster dynamic interactions between theorists and observers. Conference Website

Black Holes & Cosmology, June 15-19 2026, Granada The purpose of the international conference series Black Holes & Cosmology is to bring together world-renowned experts as well as junior researchers working on theoretical and observational aspects of black holes, particularly (but not limited to) their role in cosmology.

CosmoVerse@Bilbao 2026, September 15-19 Our understanding of the Universe is at a turning point with the predictions of the standard cosmological model and the observations from different surveys are showing tensions in several key areas. The disagreement is expressed in the value of cosmic expansion as well as in the growth of large-scale structure in the Universe. New cosmological surveys, many of which are European, may expose tension in additional areas of the concordance model. Conference Website
