Full title:
Formulation of an extended null channel formalism for a triangular gravitational wave interferometer configuration in the case of non-identical and correlated noise
Several proposed gravitational wave interferometers have a triangular configuration, such as the Einstein Telescope (ET) and the Laser Interferometer Space Antenna (LISA). For such a configuration one can construct a sky location independent or unique null channel insensitive to gravitational waves from all directions. We expand on earlier work and describe an extended null channel formalism applicable to interferometric data with non-identical as well as correlated noise sources between the different interferometers. Two examples are shown to illustrate the formalism in the context of the Einstein Telescope. Finally we highlight future research needed to transition from the mathematical formalism described here to a framework in which the formalism can be used to estimate the noise power spectral densities of the observing gravitational-wave interferometers.
