Abstract:
We present a preliminary investigation of the potential of third-generation gravitational-wave (GW) detectors for multi-messenger astronomy from the standpoint of sky localization and electromagnetic follow-up. Using simulated and optimized noise-curves for current and next generation detectors, we calculate the statistical uncertainty with which arrival time of signals from neutron star-neutron star mergers can be measured, as well as the maximal horizon distance and corresponding redshifts to the sources. Based on our preliminary findings, Cosmic Explorer, a next generation detector yet to be constructed, will have the capability to detect binary neutron star mergers from as early as the epoch of reionization (z ~ 10). Our project also concerns the configuration and calibration of a next generation detector network. From our construction of a frequency-independent toy model of calibration errors, we find that the overall uncertainty in sky localization parameters exhibits different behavior in the limit of high and low S/N. However, we aim to better understand how a more realistic, frequency dependent calibration uncertainty model affects how well we can localize gravitational wave signals with next generation detectors. Questions we focus on include: at what redshift will sky localization accuracy be limited by detector calibration? Using different combinations of detectors, what sky localization can be achieved? Our research motivates why third generation GW detector networks are crucial in enhancing signals detected and in providing insight into the sources and their physical environments.

Reader profile: The reader is reading my abstract and trying to decide whether or not to attend my talk at a conference (plausible scenario). They are familiar with gravitational wave astronomy and electromagnetic follow up.

Reader response: This abstract is interesting, but reading it gives me very little insight into why this research is relevant to the advancement of astrophysics of binary sources and their environments. It seems very broad. Why is the timing uncertainty relevant to the localization? The open questions do not really convey a good plan of what the authors intend to do, if, as I gather from reading this aspect, the authors have not done a whole lot of solid research…

Revised abstract:

Due to their increased sensitivity, third generation gravitational-wave (GW) detectors will have the capability to identify more distant compact binary with a greater degree of localization than with second-generation detectors. We present a preliminary investigation of the potential of these detectors for electromagnetic follow-up and host galaxy identification. Using simulated and optimized noise-curves for current and next generation detectors, we calculate the statistical arrival time uncertainty (used for triangulation) of signals from binary neutron star mergers, as well as the maximal horizon distance and corresponding redshifts to the sources. Based on our preliminary findings, Cosmic Explorer, a next generation detector yet to be constructed, will have the capability to detect BNS mergers from as early as the epoch of reionization (z ~ 10). Our project also concerns how detector calibration uncertainty affects sky localization. Based on the frequency-independent toy model of calibration errors we developed, our ability to localize signals with next generation detectors will predominantly depend on detector calibration. However, we aim to perform a more thorough analysis using a more realistic, frequency dependent calibration uncertainty model, combined with statistical uncertainties in all sky localization parameters. We focus on the question: at what redshift will sky localization accuracy be limited by detector calibration? Our research will be useful in determining the science requirements for next generation detectors in order to do multi-messenger astrophysics with gravitational waves.

I like your revised abstract and the subtle ways you try to reach this disinterested reader. Yes. You can increase the chances that this scientist will consider reading or attending you talk, in subtle ways. Good job on that.
