All-sky search for long-duration gravitational wave transients in the first Advanced LIGO observing run

Understand

We 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 days.

• The search targets gravitational wave transients of \unit[10 -- 500]{s} duration in a frequency band of \unit[24 -- 2048]{Hz}, with minimal assumptions about the signal waveform, polarization, source direction, or time of occurrence.
• No significant events were observed.
• %All candidate triggers were consistent with the expected background, 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.
