Sengupta, Anand et al.Anand et al.Sengupta2025-08-302025-08-302018-12-0110.1007/s41114-018-0012-92-s2.0-85046034556https://repository.iitgn.ac.in/handle/IITG2025/22706We present possible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next decade, with the intention of providing information to the astronomy community to facilitate planning for multi-messenger astronomy with gravitational waves. We estimate the sensitivity of the network to transient gravitational-wave signals, and study the capability of the network to determine the sky location of the source. We report our findings for gravitational-wave transients, with particular focus on gravitational-wave signals from the inspiral of binary neutron star systems, which are the most promising targets for multi-messenger astronomy. The ability to localize the sources of the detected signals depends on the geographical distribution of the detectors and their relative sensitivity, and 90 % credible regions can be as large as thousands of square degrees when only two sensitive detectors are operational. Determining the sky position of a significant fraction of detected signals to areas of 5–20deg2 requires at least three detectors of sensitivity within a factor of ∼ 2 of each other and with a broad frequency bandwidth. When all detectors, including KAGRA and the third LIGO detector in India, reach design sensitivity, a significant fraction of gravitational-wave signals will be localized to a few square degrees by gravitational-wave observations alone.en-UStrueData analysis | Electromagnetic counterparts | Gravitational waves | Gravitational-wave detectorsArticlehttps://link.springer.com/content/pdf/10.1007/s41114-018-0012-9.pdf143383511 December 20189843931WOS:000431468800001
