“…Our results suggest that this constraining power will improve when numerical models of merger outflows, telescope sensitivity, and GW detectors progress (see, e.g., Chornock et al 2019;Cowperthwaite et al 2019;Palmese et al 2019). Currently, significant effort is underway to add more sophisticated treatments of microphysical processes to numerical models, as well as increase the coverage of the parameter space studied with these models (Baiotti & Rezzolla 2017;Shibata & Hotokezaka 2019;Ciolfi 2020;Dietrich et al 2021;Ruiz et al 2021). The Vera Rubin Observatory, an optical, wide-field telescope expected to begin operations in 2021 (Ivezić et al 2019), will have a large impact on taking high-accuracy EM data and detecting GW events at larger distances, while telescopes such as ZTF (Dekany et al 2020) and (near-future) dedicated GW follow-up telescopes such as BlackGEM (Bloemen et al 2016) and GOTO (Gompertz et al 2020) will increase the number of detected EM counterparts.…”

In recent years, there have been significant advances in multimessenger astronomy due to the discovery of the first, and so far only confirmed, gravitational wave event with a simultaneous electromagnetic (EM) counterpart, as well as improvements in numerical simulations, gravitational wave (GW) detectors, and transient astronomy. This has led to the exciting possibility of performing joint analyses of the GW and EM data, providing additional constraints on fundamental properties of the binary progenitor and merger remnant. Here, we present a new Bayesian framework that allows inference of these properties, while taking into account the systematic modeling uncertainties that arise when mapping from GW binary progenitor properties to photometric light curves. We extend the relative binning method presented in Zackay et al. to include extrinsic GW parameters for fast analysis of the GW signal. The focus of our EM framework is on light curves arising from r-process nucleosynthesis in the ejected material during and after merger, the so-called kilonova, and particularly on black hole−neutron star systems. As a case study, we examine the recent detection of GW190425, where the primary object is consistent with being either a black hole or a neutron star. We show quantitatively how improved mapping between binary progenitor and outflow properties, and/or an increase in EM data quantity and quality are required in order to break degeneracies in the fundamental source parameters.

“…In the case of GW170817, the eventual GW signal of the black hole ring-down was too weak to confirm if or when this collapse had occurred (Abbott et al 2017d). This single event represented a breakthrough in the understanding of merger physics and the study of the origin of heavy elements in the Universe (for a review, see Ciolfi 2020). Also, it allowed the first standard siren measurement of the Hubble constant (Abbott et al 2017a;Hotokezaka et al 2019).…”

The binary neutron star merger gravitational-wave signal GW170817 was followed by three electromagnetic counterparts, including a kilonova arising from the radioactivity of freshly synthesized r-process elements in ejecta from the merger. Finding kilonovae after gravitational-wave triggers is crucial for (i) the search for further counterparts, such as the afterglow, (ii) probing the diversity of kilonovae and their dependence on the system’s inclination angle, and (iii) building a sample for multi-messenger cosmology. During the third observing run of the gravitational-wave interferometer network, no kilonova counterpart was found. We aim to predict the expected population of detectable kilonova signals for the upcoming O4 and O5 observing runs of the LIGO-Virgo-KAGRA instruments. Using a simplified criterion for gravitational-wave detection and a simple GW170817-calibrated model for the kilonova peak magnitude, we determine the rate of kilonovae in reach of follow-up campaigns and their distributions in magnitude for various bands. We briefly consider the case of GW190425, the only binary neutron star merger confirmed since GW170817, and obtain constraints on its inclination angle from the non-detection of its kilonova, assuming the source was below the follow-up thresholds. We also show that non-gravitational-wave-triggered kilonovae can be a numerous class of sources in future surveys and briefly discuss associations with short bright gamma-ray bursts. We finally discuss the detection of the jetted outflow afterglow in addition to the kilonova.

“…From the study of PSR B1913+16, it was found that the loss in energy of BNS system and reduction in orbital distance increases the amplitude and luminosity of GWs (Abbott et al, 2017) [5] , and with that the emission of EM waves increases. By combining the GWs luminosity from the BNS system and EM waves redshift of the host galaxy will make it possible to find the Hubble constant from GW standard siren determination (Ciolfi et al, 2020) [26] .…”

Detection of Gravitational waves opened a new path for cosmological study in a new approach. From the detection of gravitational waves signal by advanced LIGO, its research climbed the peak. After the collaboration of LIGO and Virgo, several observations get collected from different sources of binary systems like black holes, binary neutron stars even both binary black hole and neutron star. The rigorous detection of gravitational signals may provide an additional thrust in the study of complex binary systems, dark matter, dark energy, Hubble constant, etc. In this review paper, we went through multiple research manuscripts to analyze gravitational wave signals. Here we have reviewed the history and current situation of gravitational waves detection, and we explained the concept and process of detection. Also, we go through different parts of a detector and their working. Then multiple gravitational wave signals are focused, originated from various sources and then found correlation between them. From this, the contribution of gravitational waves in different fields like complex binary systems (black holes, neutron stars), dark matter, dark energy and Hubble Constant have been discussed in this manuscript.
