Titre |
An adapted coordinate system for light-signal-based cosmology |
|
Résumé |
The "geodetic light-cone gauge" is a convenient coordinate system for the observation of light-like signals by a geodetic observer.
After introducing it I will give two examples on how it can be applied to physically interesting problems: i) the precision determination of dark-energy parameters; ii) the description of strong gravitational lensing. If time allows I will also mention some very recent work on gravitational bremsstrahlung from massless particle collisions.
