摘要

快速射电暴（FRBs）是一种神秘的、从宇宙距离发出的短时间无线电波爆发。本文探讨了快速射电暴的各种特性，如色散测量（DM）、旋转测量（RM）、脉冲宽度、持续时间、红移分布和光谱指数。本文还介绍了我们最近对FRB宿主星系和事件率密度的研究，重点是利用CHIME/FRB发现的源重新计算事件率密度。这篇综述强调了继续研究以解开快速射电暴之谜及其不同性质的重要性。

The Properties of Fast Radio Bursts: A Short Review

Fast Radio Bursts (FRBs) are mysterious, short-duration bursts of radio waves originating from cosmological distance. This paper explores various properties of FRBs, such as Dispersion Measure (DM), Rotation Measure (RM), pulse width, duration, redshift distribution, and spectral index. The paper also introduces our recent research on FRB host galaxies and event rate density, focusing on recalculating event rate densities using sources discovered by CHIME/FRB. This review underscores the importance of continued research to unravel the mysteries of FRBs and their diverse properties.

期刊介绍： Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
