Abstract

A microshot from FRB 20220912A (Hewitt et al. 2023) satisfies the uncertainty relation ΔωΔt ≥ 1 by a factor of only ⪅3. A Crab pulsar nanoshot (Hankins & Eilek 2007) exceeds this bound by a similar factor. The number of orthogonal plasma modes contributing to the coherent radiation is also ≈ΔωΔt, placing constraints on their excitation and growth.

FRB 20220912A 微射影和蟹状 PSR 纳米射影中的辐射模式

来自 FRB 20220912A 的一个微射影（Hewitt 等人，2023 年）满足不确定性关系 ΔωΔt ≥ 1，系数仅为 ⪅3。蟹状脉冲星纳光子（Hankins & Eilek，2007 年）也以类似的系数超过了这一界限。对相干辐射有贡献的正交等离子体模式的数量也是≈ΔωΔt，这就对它们的激发和增长施加了限制。

期刊介绍： For papers that merit urgent publication, MNRAS Letters, the online section of Monthly Notices of the Royal Astronomical Society, publishes short, topical and significant research in all fields of astronomy. Letters should be self-contained and describe the results of an original study whose rapid publication might be expected to have a significant influence on the subsequent development of research in the associated subject area. The 5-page limit must be respected. Authors are required to state their reasons for seeking publication in the form of a Letter when submitting their manuscript.
