标题： Status of the O4 run and latest non-CBC results

摘要： 第四观测运行（O4）于2023年5月开始，计划持续到2025年10月。作为LVK合作组织的一员，我将涵盖两个主题：O4运行的状态和最新的非CBC结果。 O4运行的状态。 重点将放在探测器的性能和在线搜索/警报上，并引用由该合作组织提供的公开资源。此外，我还将概述去噪技术，包括有助于以低成本提高灵敏度的人工智能方法。 最新的非CBC结果。 紧凑双星并合（CBC）只是潜在的引力波源之一：连续波、爆发和随机引力波仍在被寻找。这里将展示O4公开搜索结果，或者如果前者尚未可用，则讨论最新的O3结果。 迄今为止，在所有进行的搜索中，尚未有任何引力波检测与这些非CBC源相关联。 显示英文摘要

摘要： The fourth observing run (O4) of Advanced LIGO, Virgo, and KAGRA has started in May 2023 and is planned to continue until October 2025. On behalf of the LVK Collaboration, I will cover two topics: Status of the O4 run and latest non-CBC results. Status of the O4 run. The focus will be on detectors' performance and online searches/alerts, drawing on publicly available sources provided by the collaboration. Additionally, I will give an overview of removing noise techniques, including AI approaches that help gain sensitivity at a small cost. Latest non-CBC results. Compact Binary Coalescence (CBC) is just one of the potential GW sources: Continuous Waves, Bursts, and Stochastic are still being hunted down. Here, O4 public results of searches will be presented, or the latest O3 will be discussed when the former are not yet available. So far, no GW detections have been associated with these non-CBC sources in any of the searches conducted.
