From GLC to double-null coordinates and illustration with static black holes
We present a system of coordinates deriving directly from the so-called Geodesic Light-Cone (GLC) coordinates and made of two null scalars intersecting on a 2-dimensional sphere parameterized by two…
Relations between physical observables: what is better?
We investigate some possible relations between physical observables and estimate the "cosmic variance" which affects these measurements. We focus on redshift and angular-distance and we discuss the…
Multimessenger time delays from lensed gravitational waves
We investigate the potential of high-energy astrophysical events, from which both massless and massive signals are detected, to probe fundamental physics. In particular, we consider how strong…

Time of flight of ultra-relativistic particles in a realistic Universe: a viable tool for fundamental physics?
Light-cone averaging in cosmology: formalism and applications
We present a general gauge invariant formalism for defining cosmological averages that are relevant for observations based on light-like signals. Such averages involve either null hypersurfaces…
Geodesic-light-cone coordinates and the Bianchi I spacetime
The geodesic-light-cone (GLC) coordinates are a useful tool to analyse light propagation and observations in cosmological models. In this article, we propose a detailed, pedagogical, and rigorous…
Looking Back with Neutrinos
We briefly discuss the history of suggestions for time- of-flight effects due to non-zero neutrino mass and a recent proposal that such effects can be used to determine the parameters of cosmology.…
Planck 2015 results - XIII. Cosmological parameters
This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. Our results are in…
Measurement of the neutrino velocity with the OPERA detector in the CNGS beam
A bstractThe OPERA neutrino experiment at the underground Gran Sasso Laboratory has measured the velocity of neutrinos from the CERN CNGS beam over a baseline of about 730 km. The measurement is…
A Small, Rapid Optical-IR Response Gamma-Ray Burst Space Observatory Concept: The NGRG
After Swift, there is no sure plan to furnish a replacement for the rapidly disseminated, high-precision GRB positions it provides, nor a new type of observatory to probe new GRB parameter space. We…
