“…Advanced LIGO (Aasi et al 2015;Abbott et al 2016) and Virgo (Acernese et al 2015) have detected gravitational wave signals from ten binary black hole merger events during their first two observation runs, O1 and O2 (Abbott et al 2018a). Upcoming observing runs will see further sensitivity upgrades to both LIGO and Virgo, as well as the prospects of a fourth detector, KAGRA (Somiya 2012;Aso et al 2013;Akutsu et al 2018), joining the network. A fifth detector is being built in India (Iyer et al 2011).…”

We search for signatures of gravitational lensing in the binary black hole events detected by Advanced LIGO and Virgo during their first two observational runs. In particular, we look for three effects: 1) evidence of lensing magnification in the individual signals due to galaxy lenses, 2) evidence of multiple images due to strong lensing by galaxies, 3) evidence of wave optics effects due to point-mass lenses. We find no compelling evidence of any of these signatures in the observed gravitational wave signals. However, as the sensitivities of gravitational wave detectors improve in the future, detecting lensed events may become quite likely.

Microlenses with typical stellar masses (a few M ) have traditionally been disregarded as potential sources of gravitational lensing effects at LIGO/Virgo frequencies, since the time delays are often much smaller than the inverse of the frequencies probed by LIGO/Virgo, resulting in negligible interference effects at LIGO/Virgo frequencies. While this is true for isolated microlenses in this mass regime, we show how, under certain circumstances and for realistic scenarios, a population of microlenses (for instance stars and remnants from a galaxy halo or from the intracluster medium) embedded in a macromodel potential (galaxy or cluster) can conspire together to produce time delays of order one millisecond which would produce significant interference distortions in the observed strains. At sufficiently large magnification factors (of several hundred), microlensing effects should be common in gravitationally lensed gravitational waves. We explore the regime where the predicted signal falls in the frequency range probed by LIGO/Virgo. We find that stellar mass microlenses, permeating the lens plane, and near critical curves, can introduce interference distortions in strongly lensed gravitational waves. For those lensed events with negative parity, (or saddle points, never studied before in the context of gravitational waves), and that take place near caustics of macromodels, they are more likely to produce measurable interference effects at LIGO/Virgo frequencies. This is the first study that explores the effect of a realistic population of microlenses, plus a macromodel, on strongly lensed gravitational waves.

“…LIGO and Virgo started the third observing run (O3) in April 2019. KAGRA, the first cryogenic underground GW observatory, is now under construction in Japan [8][9][10][11], and it is planned to join the O3. In addition, the third generation GW detectors such as Einstein Telescope (ET) [12] and Cosmic Explorer [13] are being proposed.…”

Dark matter signals on a laser interferometer

et al. 2020

WIMPs are promising dark matter candidates. A WIMP occasionally collides with a mirror equipped with interferometric gravitational wave detectors such as LIGO, Virgo, KAGRA and Einstein Telescope (ET). When WIMPs collide with a mirror of an interferometer, we expect that characteristic motions of the pendulum and mirror are excited, and those signals could be extracted by highly sophisticated sensors developed for gravitational wave detection. We analyze the motions of the pendulum and mirror, and estimate the detectability of these motions. For the "Thin-ET" detector, the signal to noise ratio may be 1.7 m DM 100 GeV , where mDM is the mass of a WIMP. We may set a more strict upper limit on the cross section between a WIMP and a nucleon than the limits obtained by other experiments so far when mDM is approximately lower than 0.2 GeV. We find an order of magnitude improvement in the upper limit around mDM = 0.2 GeV.
