Sengupta, Anand et al.Anand et al.Sengupta2025-08-302025-08-302018-02-1410.1088/1361-6382/aaab762-s2.0-85042488011https://repository.iitgn.ac.in/handle/IITG2025/22910We present the results of a search for long-duration gravitational wave transients in the data of the LIGO Hanford and LIGO Livingston second generation detectors between September 2015 and January 2016, with a total observational time of 49 d. The search targets gravitational wave transients of 10500 s duration in a frequency band of 242048 Hz, with minimal assumptions about the signal waveform, polarization, source direction, time of occurrence. No significant events were observed. As a result we set 90% confidence upper limits on the rate of long-duration gravitational wave transients for different types of gravitational wave signals. We also show that the search is sensitive to sources in the Galaxy emitting at least ∼10^-8 M⊙c² in gravitational waves.falsegravitational waves | LIGO-Virgo | long duration transientArticlehttps://iopscience.iop.org/article/10.1088/1361-6382/aaab76/pdf1361638214 February 20181806500918WOS:000425123900002
