Quantum Gravitational Imprints on Cosmology

Quantum Gravitational Imprints on Cosmology surveys the remarkable advancements in our understanding of the interface between quantum gravity theories and cosmology that have been achieved over the past four decades. 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.These fascinating developments are explained at a level accessible to advanced PhD students, making the book a valuable resource for early-career researchers approaching these fields for the first time or interested in exploring them in greater depth.
