This study reports a pulsar-like swing in the polarization position angle of the nearby fast radio burst FRB 20221022A, suggesting magnetospheric origins and ruling out short-period pulsars as progenitors.

The paper reports polarisation position angle (PA) evolution in a single fast radio burst, FRB 20221022A, detected with CHIME and localized to the nearby host galaxy MCG+14-02-011 (~65 Mpc). Over the ~2.5 ms burst, the PA rotates by ~130 degrees in an “S”-shaped pattern, which the authors find can be well-described by the rotating vector model (RVM), favoring magnetospheric emission near the central engine and disfavoring shock-based models far from the source. A key caveat is that the unknown period/duty cycle prevents determining inclination and magnetic obliquity, and the authors therefore cannot uniquely constrain the geometry beyond ruling out extremely short-period pulsars as progenitors. Relevance to endometriosis: the paper’s corpus inclusion is based on a keyword match in the upstream search index, but the provided text does not explicitly discuss endometriosis or adenomyosis.

Abstract

Abstract Fast radio bursts (FRBs) last for milliseconds and arrive at Earth from cosmological distances. While their origin(s) and emission mechanism(s) are presently unknown, their signals bear similarities with the much less luminous radio emission generated by pulsars within our Galaxy and several lines of evidence point toward neutron star origins. For pulsars, the linear polarisation position angle (PA) often exhibits evolution over the pulse phase that is interpreted within a geometric framework known as the rotating vector model (RVM). Here, we report on a fast radio burst, FRB 20221022A, detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) and localized to a nearby host galaxy (∼ 65 Mpc), MCG+14-02-011. This one-off FRB displays a ∼ 130 degree rotation of its PA over its ∼ 2.5 ms burst duration, closely resembling the “S”-shaped PA evolution commonly seen from pulsars and some radio magnetars. The PA evolution disfavours emission models involving shocks far from the source and instead suggests magnetospheric origins for this source which places the emission region close to the FRB central engine, echoing similar conclusions drawn from tempo-polarimetric studies of some repeating sources. This FRB’s PA evolution is remarkably well-described by the RVM and, although we cannot determine the inclination and magnetic obliquity due to the unknown period/duty cycle of the source, we can dismiss extremely short-period pulsars (e.g., recycled millisecond pulsars) as potential progenitors. RVM-fitting appears to favour a source occupying a unique position in the period/duty cycle phase space that implies tight opening angles for the beamed emission, significantly reducing burst energy requirements of the source.

While their origin(s) and emission mechanism(s) are presently unknown, their signals bear similarities with the much less luminous radio emission generated by pulsars within our Galaxy and several lines of evidence point toward neutron star origins. For pulsars, the linear polarisation position angle (PA) often exhibits evolution over the pulse phase that is interpreted within a geometric framework known as the rotating vector model (RVM). Here, we report on a fast radio burst, FRB 20221022A, detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) and localized to a nearby host galaxy (∼ 65 Mpc), MCG+14-02-011. This one-off FRB displays a ∼ 130 degree rotation of its PA over its ∼ 2.5 ms burst duration, closely resembling the “S”-shaped PA evolution commonly seen from pulsars and some radio magnetars. The PA evolution disfavours emission models involving shocks far from the source and instead suggests magnetospheric origins for this source which places the emission region close to the FRB central engine, echoing similar conclusions drawn from tempo-polarimetric studies of some repeating sources. This FRB’s PA evolution is remarkably well-described by the RVM and, although we cannot determine the inclination and magnetic obliquity due to the unknown period/duty cycle of the source, we can dismiss extremely short-period pulsars (e.g., recycled millisecond pulsars) as potential progenitors. RVM-fitting appears to favour a source occupying a unique position in the period/duty cycle phase space that implies tight opening angles for the beamed emission, significantly reducing burst energy requirements of the source.","manuscriptTitle":"A pulsar-like swing in the polarisation position angle of a nearby fast radio burst","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-02-16 06:52:59","doi":"10.21203/rs.3.rs-3940906/v1","editorialEvents":[],"status":"published","journal":{"display":false,"email":"[email protected]","identity":"nature","isNatureJournal":true,"hasQc":false,"allowDirectSubmit":false,"externalIdentity":"nature","sideBox":"Learn more about [Nature](http://www.nature.com/nature/)","snPcode":"","submissionUrl":"","title":"Nature","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"ejp","reportingPortfolio":"Nature","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"f8a04ea7-1d8a-4230-afd4-e210262e8da4","owner":[],"postedDate":"February 16th, 2024","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[{"id":28677490,"name":"Physical sciences/Astronomy and planetary science/Astronomy and astrophysics/Transient astrophysical phenomena"},{"id":28677491,"name":"Physical sciences/Astronomy and planetary science/Astronomy and astrophysics/High-energy astrophysics"}],"tags":[],"updatedAt":"2025-01-02T08:05:47+00:00","versionOfRecord":{"articleIdentity":"rs-3940906","link":"https://doi.org/10.1038/s41586-024-08184-4","journal":{"identity":"nature","isVorOnly":false,"title":"Nature"},"publishedOn":"2025-01-01 05:00:00","publishedOnDateReadable":"January 1st, 2025"},"versionCreatedAt":"2024-02-16 06:52:59","video":"","vorDoi":"10.1038/s41586-024-08184-4","vorDoiUrl":"https://doi.org/10.1038/s41586-024-08184-4","workflowStages":[]},"version":"v1","identity":"rs-3940906","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-3940906","identity":"rs-3940906","version":["v1"]},"buildId":"J0_U0BvcaRcwD8yVFaRlm","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
