Data analysis

Data analysis

The development and implementation of data analysis algorithms is essential for the searches 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.

The permanent independent research group “Searching for Continuous Gravitational Waves” at the AEI aims to detect gravitational waves from spinning neutron stars, and thus to observe these stars via a completely different physical mechanism, which would carry important new information about their internal structure and composition.

The Einstein@Home project comes with a screensaver that displays information about the processing on the volunteer's computer. The screensaver shows the rotating celestial sphere with the brightest stars and their constellations. Magenta and red points are known pulsars and supernova remnants, respectively, which are concentrated along the plane of the Milky Way. The orange crosshair shows the sky position currently being analysed. Additional processing information and computation details are shown in the corners of the screen.
