Improving agnostic searches of Gravitational Waves from Neutron Star instabilities using image filtering

Understand

In this paper I present a method to enhance the search sensitivity for long transient Gravitational Waves produced by Neutron Star instabilities.

• This method consists in a selective image filter, called Triangular Filter, to be applied to data spectrograms.
• It is shown that thanks to this implementation a 20% gain in sensitivity is achievable.
