4 天之前 · O5 is currently planned to start in late 2027. The April/May break in observing is prompted by the importance of repairing a faulty beam tube gate valve at LIGO Livingston site before this year’s hurricane season and other work on the other detectors of the network that will reduce risk related to the O4-O5 transition.

2024年10月14日 · Here, we study the detectability of the prompt emission and afterglows produced by the relativistic jets launched by BNS mergers that will be detected by LIGO-Virgo-KAGRA (LVK) during their fifth observing run (O5), and by next generation (XG) GW detectors (Einstein Telescope and Cosmic Explorer).

2023年10月23日 · We simulate the current LIGO-Virgo-KAGRA (LVK) observing run (O4) using up-to-date sensitivity and up-time values as well as the next observing run (O5) using predicted sensitivities.

2013年4月2日 · We estimate the sensitivity of the network to transient gravitational-wave signals for the third (O3), fourth (O4) and fifth observing (O5) runs, including the planned upgrades of the Advanced LIGO and Advanced Virgo detectors.

Current (as of January 2023) projected timeline of observing runs 4 (O4) and 5 (O5), and expected binary neutron star (BNS) detection range for LIGO, Virgo, and KAGRA detectors. By Kimberly Burtnyk. UPDATE: This story was originally published in June, 2022. For the latest estimates of the O4 observing run timeline, visit Observing Plans.

2023年5月24日 · The O5 start dates, duration, and sensitivities are current best guesses, and will likely be adjusted as we approach that run for all the detectors. graphic: LVK Past and planned observing runs of the LIGO, Virgo, and KAGRA gravitational-wave detectors.

2022年2月26日 · As of 2021, the LIGO-Virgo-KAGRA (LVK) Collaboration is working to establish the International Gravitational Wave Network (IGWN) which is conceived as an organization to facilitate coordination among ground-based, gravitational-wave-detector projects across the globe.

2023年12月1日 · As evident from Fig. 10 and Table 4, an updated LVK network during O5 with significantly improved sensitivities may present the first opportunity to discover a small sample of kilonovae, which would enable exciting new population studies …

我们使用当前灵敏度和正常运行时间值以及使用下一次观测运行 (O5) 的预测灵敏度来模拟当前的 LIGO-Virgo-KAGRA (LVK) 观测运行 (O4)。 我们发现 LVK O4 期间可发现的千新星数量为 ${ 1}_{- 1}^{+ 4}$ 或 ${ 2 }_{- 2 }^{+ 3 }$（置信度为 90%）取决于合并双星中 NS 质量的分布，其 ...

Virgo-KAGRA combination as ‘LVK’. This LSC-Virgo-KAGRA Observational Science White Paper, which is updated yearly (and was formerly called the LSC-Virgo White Paper on Gravitational Wave Data Analysis and Astrophysics), describes the planned activities of the members of the four astrophysical search working groups, including science goals
