Perimeter Institute Profile

About

Luis Lehner is a physicist who focuses on understanding strongly gravitating systems, both in standard four-dimensional spacetimes and in higher-dimensional ones.

In four dimensions, systems containing black holes and neutron stars play a central role as drivers of spectacular phenomena such as AGN and gamma-ray bursters, and the generation of gravitational waves strong enough to be detected by Earth- and space-based facilities. The detection of these gravitational waves will enable scientists to infer important properties of their sources, by comparing the measured signals with those predicted by theoretical models.
Obtaining these models is a formidable challenge, and in many situations can only be done via numerical simulations. In higher-dimensional scenarios, understanding gravitational effects may shed light on the classical limit of prospective theories of gravity. Again, in many scenarios this requires numerical simulations.

Lehner’s work concentrates on obtaining these simulations, which requires work at the analytical and computational levels, and on extracting sought-after information from them. Research in this area is referred to as numerical relativity (NR), and is currently pushing the boundaries of analytical and numerical capabilities, and those of the largest available computational resources.
