Quantum Gravity Effects in Black Holes and Gravitational Waves
Abstract: Quantum-gravity effects as noise for gravity-wave detectorsI discuss a mechanism that can allow Planck scale effects to manifest themselves as a source of lof-frequency noise for interferometers.  The mechanism requires a discrete formulation of dynamics at the Planck scale._______________... read more

Photons and Quantum Gravity in Astrophysics
Abstract: Asymptotically safe inflation and CMB polarizationThe presence of complex critical exponents in the scaling behavior of the Newton constant and Cosmological  constant has dramatic consequences at the inflation scale. In particular an infinite number of unstable de-Sitter vacua emerges from ... read more

Gravity in (and with) Quantum Spacetime
Abstract: Over the last decade there has been strong interest in the theory and phenomenology of particle propagation in quantum spacetime. The main results concern possible Planck-scale modifications of the "dispersion" relation between energy and momentum of a particle. I review results es... read more

Fermi's lazy photon, the GEO600 anomaly, and the no-Riemann-no-pie theorem
Abstract: I comment on rather significant recent developments that are relevant for proposals I had presented in previous PI seminars. The Fermi/GLAST space telescope has reported observations that would naturally fit previous formalizations of Planck-scale-induced in-vacuo dispersion (but also quite a few ot... read more

A perspective on Quantum Gravity Phenomenology
Abstract: I discuss the status of Quantum Gravity Phenomenology, focusing separately on the 3 key areas: ability to discover, ability to constrain, and ability to falsify. And I stress the importance of adopting carefully taylored test theories as a remedy to difficulties encountered when comparing experiment... read more
