TL;DR
This paper evaluates how the Vera C. Rubin Observatory's LSST can identify host galaxies of fast radio bursts (FRBs) and aid in cosmological measurements, showing high potential even with photometric redshift uncertainties.
Contribution
It introduces a predictive model for FRB host galaxy brightness and redshift distributions, assessing LSST's effectiveness in FRB host identification and cosmology.
Findings
Rubin LSST can identify 65-81% of FRB host galaxies.
Photometric redshifts cause only a 7% decrease in $H_0$ measurement precision.
Dimmer, higher-redshift hosts could significantly impact cosmological sensitivity.
Abstract
Identifying the host galaxies of fast radio bursts (FRBs), and comparing their redshifts and dispersion measures, has unlocked a new probe of the cosmological distribution of ionised gas. However the necessary optical observations to identify FRB hosts, and measure their redshifts, are becoming increasingly onerous as the detection rate of precisely localised FRBs increases. Here we analyse the ability of the Legacy Survey of Space and Time (LSST), being conducted by the Vera C. Rubin Observatory, to identify FRB host galaxies, and the utility of LSST photometric redshifts for FRB cosmology. By combining a model of FRB host galaxy r-band magnitudes, , with predictions for the FRB z-DM distribution, we create a method to predict the distribution for the host galaxies of FRBs detected by radio surveys. We then predict these distributions for the coherent modes of the…
