GWFish

GWFish is a Fisher matrix code geared towards future gravitational-wave detectors.

It is able to provide estimates of the signal-to-noise ratio and of the errors on our estimates of the parameters, for a signal as it would be seen by one or more future detectors, among:

• LIGO / Virgo in their fifth observing run;

• Kagra;

• Einstein Telescope;

• Lunar Gravitational Wave Antenna;

• Cosmic Explorer;

• LISA;

• Voyager.

It is able to account for a time-varying antenna pattern, since we expect these detectors to be sensitive in the low-frequency regime, for which the motion of the Earth / Moon / satellites is significant across the signal duration.

For more information about the theory than what is discussed here, refer to the GWFish paper.

This software is developed by the gravitation group at the Gran Sasso Science Institute.
