“…One example of such an avenue is gravitationally lensed GWs, the first of which may be possible to observe in the next few years (Ng et al 2018;Li et al 2018;Oguri 2018).

Advanced LIGO and Advanced Virgo might be able to observe the first lensed gravitational waves in the coming years. With the addition of the KAGRA and LIGO India detectors to the detector network and with the future construction of the Einstein Telescope we might be able to observe hundreds of lensed events. Ground-based gravitational-wave detectors can resolve arrival-time differences on the order of the inverse of the observed frequencies. The LIGO and Virgo frequency band spans from a few Hz to a few kHz, therefore the typical time resolution of current interferometers is on the order of milliseconds. When microlenses are embedded in galaxies or galaxy clusters, lensing can become more prominent and result in observable time delays at LIGO and Virgo frequencies. Therefore, gravitational waves might offer an exciting alternative probe of microlensing. However, only a few lensing configurations have currently been worked out in the context of gravitational-wave lensing. In this paper, we present LENSINGGW, a PYTHON package designed to handle both strong lensing and microlensing of compact binaries and the related gravitational-wave signals in the geometrical optics limit. This synergy paves the way for systematic parameter space investigations and for the detection of arbitrary lens configurations and compact sources. Here we focus on the LIGO and Virgo frequencies. We demonstrate the working mechanism of LENSINGGW and its use in studying microlenses that are embedded in galaxies.

“…omitting higher order contributions. This would definitely affect the phase evolution of the GW emitted simultaneously [25,44]. However, in the following discussion, one assumes ḟγ due to the DP radiation is much smaller than that due to the GW given by, ḟgw = 48 5π…”

In this work, we consider the burst signal of the dark photon, the hypothetical vector boson of the U (1)B or U (1)B−L gauge group, generated by a compact binary star system. The absence of the signal in the laser interferometer puts bounds on the coupling constant to the ordinary matter. It turns out that if the dark photon is massless, 2 is on the order of 10 −37 − 10 −33 at most; in the massive case, the upper bound of 2 is about 10 −38 − 10 −31 in the mass range from 10 −19 eV to 10 −11 eV. These are the first bounds derived from the interferometer observations independent of the assumption of dark photons being dark matter.

“…It is also interesting to know that it may not be necessary to rely on the electromagnetic counterpart to determine the redshift of the source as discussed in Refs. [5][6][7][8]. The GW can also serve as a probe into fundamental physics [9], such as the nature of gravity [10] and spacetime [11].…”

The coherent nature of gravitational wave emanating from a compact binary system makes it possible to detect some interference patterns in two (or more) signals registered simultaneously by the detector. Gravitational lensing effect can be used to bend trajectories of gravitational waves, which might reach the detector at the same time. Once this happens, a beat pattern may form, and can be used to obtain the luminosity distance of the source, the lens mass, and cosmological parameters such as the Hubble constant. Crucial question is how many such kind of events could be detected. In this work, we study this issue for the future space-borne detectors: DECIGO and its downscale version, B-DECIGO. It is found out that there can be a few tens to a few hundreds of lensed gravitational wave events with the beat pattern observed by DECIGO and B-DECIGO per year , depending on the evolution scenario leading to the formation of double compact objects. In particular, black hole-black hole binaries are dominating population of lensed sources in which beat patterns may reveal. However, DECIGO could also register a considerable amount of lensed signals from binary neutron stars, which might be accompanied by electromagnetic counterparts. Our results suggest that, in the future, lensed gravitational wave signal with the beat pattern could play an important role in cosmology and astrophysics.
