CPT Violations in Astrophysics and Cosmology

G. Auriemma

Abstract

In this paper it is given a brief review of the current limits on the
magnitude of CPT and Lorentz Invariance violations, currently predicted
in connection with quantum gravity and string/M-theory, that can be
derived from astrophysical and cosmological data. Even if not completely
unambiguous, these observational tests of fundamental physics are
complementary to the ones obtained by accelerator experiments and by
ground or space based direct experiments, because potentially can access
very high energies and large distances.
