GCRT J1745—3009: a precessing radio pulsar?

Abstract: A unique transient bursting radio source, GCRT J1745−3009, has been discovered near the direction of the Galactic Centre. The explanation of this phenomenon is still an open question, although some efforts to understand its nature have been made. This Letter shows that most of the observed features can be reproduced by our proposed precessing pulsar model. It is found that the precession angle of the pulsar should be larger (≳15°) than that of previously known precessing pulsars, which have a precession angle … Show more

“…SSs can explain many observational phenomena in astrophysics, including pulsar glitches, sub-pulse drifts, the presence of extremely strong magnetic fields, and the transient bursts of GCRT J1745−3009 [10,23,[68][69][70][71], even for fast radio bursts related to galactic magnetars [72,73]. The tidal deformability of merging binary SSs, along with the analysis of ejecta and light curves, has been investigated in previous works [74][75][76].…”

“…This led its discoverers to conclude that it was beaming coherent emission to us. Second, as a transient source, it was very unusual since no other transient radio source has been observed to produce pulses with such regularity, unless one wishes to interpret it as an extreme nulling pulsar as have Zhu and Xu [33]. A third unusual feature is its unusually long period of 77 minutes.…”

“…We simply don't know what it is. Many reasonable natural explanations have been proposed and are currently undergoing peer review [12,9], but the question remains as to how does one definitively say that a seemingly coherent, narrow band radio transient is natural or not. Given the possible kilo-parsec distances from which this signal may emanate and the natural forces that distort it along a path to us, the answer is not certain and demands that we apply a genuine conservatism when building a probabilistic case for extraterrestrial intelligence based upon the collection of large numbers of provocative radio transients.…”
