Now Published in PRD: Dual Cutler–Vallisneri Corrections

My first solo-author paper, introducing the Dual Cutler–Vallisneri corrections for PSD drift in zero-latency gravitational-wave searches, has been published in Physical Review D.

I’m delighted to share that Dual Cutler–Vallisneri Corrections: Mitigating PSD Drift in Zero-Latency Gravitational-Wave Searches has been published in Physical Review D  [1]. This is my first solo-author paper, and it marks the first entry in the Gauge Theoretic Signal Processing (GTSP) program to complete peer review.

The paper develops an analytic, causal framework for correcting the timing, phase, and SNR biases that spectral drift induces in real-time early-warning pipelines, systematics that would otherwise broaden sky maps and erode detection volume for multi-messenger follow-up. For the full technical walkthrough, see the original announcement:

My thanks to the reviewers and editors at PRD, and to everyone in the LIGO Scientific Collaboration who offered feedback along the way.
