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.

Readership: The target readership is a wide academic audience, professional or interested in modern cosmology, astrophysics and particle physics and their fundamental relationship. It can be used as a text book for courses in theoretical physics, cosmology, high energy physics and astrophysics, astroparticle physics at the undergraduate, graduate and postgraduate levels. The book may be useful for specialists in various particular fields of astronomy and particle physics to find possible application of their experience in the studies at the frontiers of fundamental knowledge. In particular, it would be very beneficial for Master's or PhD students in cosmology and particle physics, and also for postdocs and even for professors and other senior researchers in this field. Even though our book is primarily a monograph, it can be used for advanced PhD courses on cosmology and particle physics as well. The current ideas on the Dark Universe, Black holes, as well as on the fundamental structure of micro- and macro worlds are of interest for the general audience and the presentation of these ideas, avoiding technical details, but giving their qualitative intuitive understanding can attract a much wider audience. The book can also be of interest to applied mathematicians, who are working on various aspects of quantum gravity. The field of quantum gravity has surprisingly used various avenues of mathematics which are not much talked about in contemporary theoretical physics and this has led to an increased attention of mathematicians in this field, and this book can allow mathematicians, right from advanced PhD students to Professors, to perhaps identify new areas where novel mathematics could be applied in physical systems.
Maxim Yu. Khlopov is a distinguished physicist with a robust educational background, holding an MSc (honours) from the Moscow Physical Technical Institute (1974), a PhD from the Institute of High Energy Physics (1977), and a DSc from the Moscow Engineering Physics Institute (1986). His professional journey began as a Research Scientist at the Keldysh Institute of Applied Mathematics (1977–1989), followed by a role as Main Research Scientist at the Special Astrophysical Observatory (1987–1989) and returning to the Keldysh Institute (1989–2004). Since 1991, he has served as a Full Professor of Physics at the National Research Nuclear University "MEPhI" and, since 1992, as President of the Centre for Cosmoparticle Physics "Cosmion." He also held a position as Full Professor at University La Sapienza in Rome (2002–2004) and has been the Director of the Virtual Institute of Astroparticle Physics in Paris since 2007. His expertise encompasses cosmology and particle physics, particularly beyond the Standard Model, the physics of the very early Universe, primordial black holes, and dark matter. He has authored 470 scientific articles and 25 books and monographs, including notable works such as Cosmoparticle Physics and Basics of Cosmoparticle Physics. An accomplished speaker, he has been invited to present at 112 international conferences. Maxim is also an editorial board member of the International Journal of Modern Physics D.
Oem Trivedi is a research associate student at the International Centre for Space and Cosmology at Ahmedabad, India. His research interests cover a wide range on the intersection of cosmology and particle physics, spanning from cosmic inflation and the early universe to dark energy, black holes, space-time singularities and the death of the universe. His work seeks out the implications of quantum gravity on all these aspects of cosmology as well. He has done significant recent work especially on various aspects of holographic dark energy, cosmological singularities and the far future of the universe. He is a fellow of the Royal Astronomical Society, has authored more than 25 papers on cosmology and has also referred for more than 10 journals. He is also a member of the LSST Dark Energy Science Collaboration, the WST collaboration, the Cosmic Explorer consortium, the EU Cosmoverse working group, alongside being a member of the American Physical Society. He has active collaborations with physicists across every inhabited continent and is also the co-founder and general director of the CYW Fair. He also holds the record for the highest number of conference talks as an undergrad. He is the recipient of several governmental and non-governmental awards for his work in physics. He is also a guest editor of a special issue in the Symmetry Journal on Quantum Gravitational Aspects of Cosmology.
