标题： Radio pulsar populations

摘要： 本文旨在概述脉冲星统计领域的现状。 简单来说，我们希望通过来自不同望远镜的多种巡天观测到的对象样本，推断潜在样本的性质，并将其与其他天体物理种群（例如超新星遗迹或X射线双星）联系起来。 我们需要解决的主要问题是，像许多科学领域一样，观测到的种群往往受到多种选择效应的严重影响。 在回顾了与射电脉冲星相关的主效应之后，我讨论了校正这些效应的技术，并总结了一些最新的结果。 或许我想在这篇文章中强调的主要观点是，目前用来描述种群的模型还远远不够完善，常常受到输入参数之间强烈的协方差影响。 尽管如此，基于现有数据，我们可以得出一些关于中子星演化的非常有趣的结果。 虽然这篇综述的重点将是孤立银河系脉冲星的种群，但我也会简要评论毫秒脉冲星和双星脉冲星，以及球状星团和麦哲伦云中的脉冲星内容。 显示英文摘要

摘要： The goal of this article is to summarize the current state of play in the field of radio pulsar statistics. Simply put, from the observed sample of objects from a variety of surveys with different telescopes, we wish to infer the properties of the underlying sample and to connect these with other astrophysical populations (for example supernova remnants or X-ray binaries). The main problem we need to tackle is the fact that, like many areas of science, the observed populations are often heavily biased by a variety of selection effects. After a review of the main effects relevant to radio pulsars, I discuss techniques to correct for them and summarize some of the most recent results. Perhaps the main point I would like to make in this article is that current models to describe the population are far from complete and often suffer from strong covariances between input parameters. That said, there are a number of very interesting conclusions that can be made concerning the evolution of neutron stars based on current data. While the focus of this review will be on the population of isolated Galactic pulsars, I will also briefly comment on millisecond and binary pulsars as well as the pulsar content of globular clusters and the Magellanic Clouds.
