Reply to the comment on ''Quantum sensor networks as exotic field telescopes for multi-messenger astronomy''

TL;DR

This paper refutes a claim that exotic low-mass fields hinder multi-messenger astronomy, showing that under certain conditions, their interaction can actually enhance detection capabilities.

Contribution

It demonstrates that the impact of ELF-matter interactions on multi-messenger astronomy is not universally negative and can improve detection prospects in specific coupling regimes.

Findings

Screening effects are negligible in certain coupling ranges.

ELF-matter interaction can reduce the delay between signals.

The proposed method enhances multi-messenger detection sensitivity.

Abstract

The comment by Stadnik [arXiv:2111.14351v1] claims that "back-action", i.e. interaction of exotic low-mass fields (ELF) with ordinary matter, "prevents the multi-messenger astronomy on human timescales." We strongly disagree with this blanket claim. This is {\em not a general conclusion}, as Stadnik's statement entirely relies on a specific sign of the ELF-matter interaction. As we demonstrate, there are coupling constant ranges when, in fact, the screening effects are irrelevant. In addition, the delay between the arrival of the ELF and gravitational wave bursts is reduced by the ELF-ordinary matter interaction, improving the discovery reach of our proposed novel, exotic physics, modality in multi-messenger astronomy.
