Observational Relativity and Cosmology

Observational Relativity and Cosmology

This department focuses on direct observational consequences of General Relativity, including the search/analysis of gravitational wave (GW) data, and operation of the Einstein@Home project, looking for weak radio, gamma-ray and GW signals from spinning neutron stars.

The most important research area of our department is the development and implementation of data analysis algorithms to search for the different expected types of gravitational wave sources. This includes burst, stochastic, continuous wave, and inspiral signals in data from ground-based gravitational wave detectors.

Searches for weak gravitational wave signals are very compute-intensive. In some cases, the lack of computing resources makes the searches substantially less sensitive than would be possible using the same experimental data, but with infinite computing power. For this reason, one of the central activities of the group is to maintain and increase the computing resources available to us. The group operates the ATLAS computing cluster, which is the world's largest and most powerful resource dedicated to gravitational wave searches and data analysis. It also plays a leading role in the Einstein@Home project, which uses computing power donated by the general public to search for gravitational waves and electromagnetic emission from neutron stars.

Research topics

The high-throughput computing cluster Atlas is the world's largest and most powerful resource dedicated to gravitational-wave searches and gravitational-wave data analysis. It offers a unique environment for scientists to solve computational problems too large for a single or a few PCs. [more]
Einstein@Home is one of the largest distributed volunteer computing projects in the world and has almost 480,000 participants. Their computers provide a sustained computing power of roughly 9.3 PetaFlop/s. If the project were listed on the Top-500, Einstein@Home would be one of the 25 most powerful computers in the world (in the June 2020 list). [more]
The research of the compact binary coalescence (CBC) group is concerned with gravitational waves from binary systems consisting of compact objects (black holes and/or neutron stars) in a compact orbit around each other. [more]
Gravitational-wave bursts searches are generic “all-purpose” searches targeting all kinds of fast GW transients, i.e., up to a few seconds duration. Burst searches are complementary to matched filter searches and allow for an “eyes-wide-open” approach towards a wide variety of potential sources. [more]
This group's main research aspects are computing-intense searches for and studies of pulsars - rapidly spinning neutron stars - through gamma-rays in previously unaccessible parameter spaces using efficient data analysis and powerful computing resources.
