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

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 \newcommand{\OOneStart}{12 ~September ~2015} \newcommand{\OOneStartShort}{September ~2015} \OOneStartShort and \newcommand{\OOneStop}{19~ January ~2016} \newcommand{\OOneStopShort}{January~ 2016} \OOneStopShort , with a total observational time of \newcommand{\OOneLivetime}{49~d} \OOneLivetime . The search targets gravitational wave transients of 10-500 s duration in a frequency band of 24-2048 Hz, with minimal assumptions about the signal waveform, polarization, source direction, or 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<SUP>-8</SUP> \newcommand{\msuncd}{M<SUB>☉ c^2</SUB>} \newcommand{\msun}{M<SUB>☉</SUB>} {\msuncd} in gravitational waves.
