A first-of-its-kind joint magnetic noise injection between LIGO Hanford and LIGO Livingston confirms that correlated magnetic noise couples into the strain channels and can be suppressed with Wiener filtering, though with residual side effects in a gravitational-wave background search.

Coherent injection of magnetic noise and its impact on gravitational-wave searches
A first-of-its-kind joint magnetic noise injection between LIGO Hanford and LIGO Livingston confirms that correlated magnetic noise couples into the strain channels and can be suppressed with Wiener filtering, though with residual side effects in a gravitational-wave background search.
