Long description:

The current cosmological model relies on inflationary theories, which incorporate baryosynthesis, dark matter, and dark energy. Supported by precise cosmological data, it necessitates physics beyond the standard models of fundamental forces, including gravity. This connection between macroscopic gravity on large scales and quantum gravity on the smallest scales is where quantum gravity's nature becomes evident. Quantum gravity effects alter our classical understanding of gravitational phenomena as described by General Relativity, leading to observable deviations from the conventional cosmological model. The field of cosmoparticle physics explores the interplay between the micro and macro worlds, offering insights into the development of quantum gravity and its cosmological implications. In this work we hence wanted to cover all the amazing developments which have happened on the interface of quantum gravity theories and cosmology, making it a valuable resource for any researcher interested in exploring these fields in depth or starting research in them.
