Tutorial

Welcome to the Cardiff Gravitational Physics tutorial pages. We have put together a few pages describing our research into black holes and gravitational waves. We hope you enjoy them.

Also, why not try searching for gravitational waves with our game Black Hole Hunter.


Two Minute Introduction

Artists impression of a black hole, jets and disk.

A brief introduction to black holes and gravitational waves, with a discussion of the effects of gravitational waves as well as the Hulse-Taylor pulsar - the most famous source of gravitational waves.

1. Black holes and Gravitational Waves
2. The Effect of Gravitational Waves
3. The Hulse-Taylor Binary Pulsar


Gravitational Wave Sources

Two merging black holes and the gravitational radiation emitted.

Very massive and fast moving systems will give off gravitational waves. By observing the gravitational wave signal from these systems we will learn more about the universe around us.

5. Supermassive Black Holes
6. Wobbling Neutron Stars


Gravitational Wave Detectors

Gravitational wave detector.

A network of gravitational wave detectors has been built around the world. The goal is the first direct detection of gravitational waves. There is also a space based decector planned.

7. Advanced LIGO
8. GEO 600: Laser interferometric gravitational wave detector
9. Virgo: ground based interferometer detector
10. Other Detectors
11. Laser Interferometer Space Antenna (LISA)


Detecting Gravitational Waves

Even in the very sensitive gravitational wave detectors, the signal we are looking for is very weak. Many sophisiticated methods have been developed to enable us to differentiate a gravitational wave signal from the background noise.
