SCoRe: A New Framework to Study Unmodeled Physics from Gravitational Wave Data

Understand

A confident discovery of physics beyond what has been consistently modeled from gravitational wave (GW) data requires a technique that can distinguish between noise artifacts and unmodeled signatures while also shedding light on the underlying physics.

• We propose a new data analysis method, \texttt{SCoRe} (Structured Correlated Residual), to search for unmodeled physics in the GW data which can cover both of these aspects.
• The method searches for structure in the cross-correlation power spectrum of the residual strain between pairs of GW detectors.
• It does so by projecting this power spectrum onto a frequency-dependent template.
