TL;DR
This paper reports the discovery and precise localization of three Fast Radio Bursts with MeerTRAP at MeerKAT, analyzes their properties, potential host galaxies, and estimates the all-sky FRB rates, revealing a possible low-fluence deficit.
Contribution
First precise localizations of FRBs with MeerTRAP, including potential host galaxy identification and detailed rate estimates based on a sample of 11 FRBs.
Findings
FRBs localized to ~1 arcmin$^2$ area.
Estimated all-sky FRB rates at 1.28 GHz: ~8.2×10^3 and 2.1×10^3 per day above certain fluences.
Detected a possible low-fluence cutoff in the FRB rate-fluence relation.
Abstract
We present a sample of well-localised Fast Radio Bursts (FRBs) discovered by the MeerTRAP project at the MeerKAT telescope in South Africa. We discovered the three FRBs in single coherent tied-array beams and localised them to an area of ~1 arcmin. We investigate their burst properties, scattering, repetition rates, and localisations in a multi-wavelength context. FRB 20201211A shows hints of scatter broadening but is otherwise consistent with instrumental dispersion smearing. For FRB 20210202D, we discovered a faint post-cursor burst separated by ~200 ms, suggesting a distinct burst component or a repeat pulse. We attempt to associate the FRBs with host galaxy candidates. For FRB 20210408H, we tentatively (0.35 - 0.53 probability) identify a compatible host at a redshift ~0.5. Additionally, we analyse the MeerTRAP survey properties, such as the survey coverage, fluence…
