The exploration of the universe has recently entered a new era thanks to multi-messenger paradigm, characterized by continuous increase in quantity and quality experimental data that is obtained detection various cosmic messengers (photons, neutrinos, rays gravitational waves) from numerous origins. They give us information about their sources properties intergalactic medium. Moreover, astronomy opens up possibility search for phenomenological signatures quantum gravity. On one hand, most...

These lecture notes introduce the reader to hot big bang model, cosmological perturbations, gravitational waves, cosmic microwave background, inflation, singularity problem, constant problem and cosmology of quantum gravity.
We discuss the construction of a free scalar quantum field theory on $\ensuremath{\kappa}$-Minkowski noncommutative spacetime. do so in terms $\ensuremath{\kappa}$-Poincar\'e-invariant $N$-point functions, i.e., multilocal functions which respect deformed symmetries As shown previous paper by some us, this is only possible for lightlike version commutation relations, allow covariant algebra $N$ points that generalizes relations. solve main shortcoming our approach, prevented development...

In addition to its implications for astrophysics, the hunt GRB neutrinos could also be significant in quantum-gravity research, since they are excellent probes of microscopic fabric spacetime. Some previous studies based on IceCube had found intriguing preliminary evidence that some them might with travel times affected by quantum properties spacetime, noticeable feature spacetime would slow down while others sped up. Recently collaboration revised significantly estimates direction...
