Abstract

We employ gravitational-wave radiometry to map the gravitational waves stochastic background expected from a variety of contributing mechanisms and test the assumption of isotropy using data from Advanced LIGO0 - 1726 Hz frequency band. Finding no evidence of gravitational waves from either point sources or a stochastic background, we set limits at 90 we report upper limits on the gravitational wave energy flux per unit frequency in the range f, 0.1 - 56) 0textasciicircum8textbracerighttextdollar erg cmtextdollartextasciicircum2textbracerighttextdollar stextdollartextasciicircum1textbracerighttextdollar Hztextdollartextasciicircum1textbracerightf/25 Hz)textdollartextasciicircumtextbraceleft1textbracerighttextdollar depending on the sky location textdollarThetatextdollar and the spectral power index textdollaralpha we report upper limits on the fractional gravitational wave energy density required to close the Universe of textdollarf, 0.39-7.6) 0textasciicircum8textbracerighttextdollar srtextdollartextasciicircum1textbracerightf/25 Hz)textdollartextasciicircumalphatextdollar depending on textdollarThetatextdollar and textdollaralphaScorpius X-1, Supernova 1987 A, and the Galactic Center) yield median frequency-dependent limits on strain amplitude of textdollarh textless6.7, 5.5, and 7.0) textdollar0textasciicircum25textbraceright at the most sensitive detector frequencies between 130 - 175 Hz.

N2 - We employ gravitational-wave radiometry to map the gravitational waves stochastic background expected from a variety of contributing mechanisms and test the assumption of isotropy using data from Advanced LIGO0 - 1726 Hz frequency band.
