Abstract :
In this talk we will try to introduce
the analysis of cosmological observables
as a suitable arena for Relative
Locality phenomenology. One of the
fundamental aspects of General
Relativity is that two different
observers on two different hypersurfaces
describe spacetime with two distinct
sets of coordinates, and, thus, they
give different coordinatizations of the
same spacetime. Relative Locality is a
relativistic theory that implements
systematic nonlocalities that can emerge
in many different approaches to the
problem of Quantum Gravity. In this
theory, locality is no longer absolute,
as codified in a novel way to
mathematically express translations
between the two hypersurfaces. We will
give an explicit example of signal
analysis and related phenomenology on
cosmological observables, with relative
locality spacetime metric,
mathematically modelized on
kappa-Minkowski deformed spacetime
transformations.
