“…This impact will increase as detector sensitivity improves and new facilities are invented to detect more different types of events. Soon, when people master the technology of gravitational waves, they can observe the entire universe at once, watching a merger or explosion happen in real-time eagerly listening [9,10]. Moreover, humans will also find much new matter, as well as dark matter and dark energy, which have been bothering people for a long time.…”

In the present day, black holes have recently attracted a variety of attention. Black holes and gravitational waves were studied more than 100 years ago. From theoretical reasoning and formula derivation to detector observation, people never stop to explore these curious things. This paper mainly describes the essential information and principle of black holes, and gravitational waves, as well as the basic operation principle of LIGO detectors. The basic definition of gravitational wave and several sources of the gravitational wave is discussed in this paper. According to the analysis, the properties of waves can be used in detecting gravitational waves, as well as more hidden matter. In 1915, Einstein proposed the general theory of relativity, which foresaw the existence of black holes but did not believe that black holes were real. In the 1960s, American scientist John Wheeler first named this incredible celestial body black hole. The search for gravitational waves has had a profound impact on people. With gravitational waves, people can discover an unknown matter which can be studied and benefit humankind. These results shed light on guiding further exploration of dark energy, matters, and more black hole observations.

“…A uniform likelihood for the peak of the power spectrum in the restricted range P R (k) ≥ 10 −3 , namely the threshold to form PBHs, and zero likelihood for the peak falling below this. For comparison, we also plot the power-law integrated sensitivity curves for LIGO A+ [129], LISA [128], ET [53], and DECIGO [55,130].…”

We perform a Markov Chain Monte Carlo (MCMC) analysis of a simple yet generic multifield inflation model characterized by two scalar fields coupled to each other and nonminimally coupled to gravity, fit to Planck 2018 cosmic microwave background (CMB) data. In particular, model parameters are constrained by data on the amplitude of the primordial power spectrum of scalar curvature perturbations on CMB scales As, the spectral index ns, and the ratio of power in tensor to scalar modes r, with a prior that the primordial power spectrum should also lead to primordial black hole (PBH) production sufficient to account for the observed dark matter (DM) abundance. We find that ns in particular controls the constraints on our model. Whereas previous studies of PBH formation from an ultra-slow-roll phase of inflation have highlighted the need for at least one model parameter to be highly fine-tuned, we identify a degeneracy direction in parameter space such that shifts by ∼ 10% of one parameter can be compensated by comparable shifts in other parameters while preserving a close fit between model predictions and observations. Furthermore, we find this allowed parameter region produces observable gravitational wave (GW) signals in the frequency ranges to which upcoming experiments are projected to be sensitive, including Advanced LIGO and Virgo, the Einstein Telescope (ET), DECIGO, and LISA.

“…Despite these differences, none of the detectors can be built without proper technology, location, and enough fund supported, in fact, several detectors who are competent in such large-scale observations includes LIGO, LISA, Virgo, KAGRA, Cosmic Explorer (CE), Einstein Telescope (ET), Tianqin, dark matter detectors DARWIN, ARGO, and DAMPE, neutrino detectors Hyper-Kamiokande, JUNO and DUNE, and also Chandra X-ray Observatory CXO. What's more, different network is also applied of certain detector, e.g., LIGO-Hanford (H), LIGO-Livingston (L), Hanford-Livingston-Virgo (HLV), Hanford-Livingston (HL), Hanford-Virgo (HV) and Livingston-Virgo (LV) [15]. With tench, as well as academic advancing, researchers have been trying to improve the instruments to allow for further observations, increasing in configurations, distances and precision than previously allowed.…”

Black hole is a kind of special celestial subject whose density is so great that even the light cannot escape, which has always been a popular topic. This study will present the recent progress of observation related to three quantities of black holes. As a leading-in, we first introduced some of the most commonly discussed black holes by demonstrating their field equations, metric, and some other representative quantities. On this basis, the formation process of a black hole will be described. In addition, a picture of the detectors used in cosmology observation is discussed before getting any further into the methods applied in observation. Subsequently, we summarized observations regarding the three elements of a black hole (mass, charge and spin). For these three different characters of black hole, different methods and theories were put into use, including gravitational retro-lensing, twin-peak QPOs, accretion disks, continuum fitting method, and black body radiation. Eventually, possible limitations are evaluated and possible improving approaches on current observations are proposed. Overall, these results shed light on guiding further researches focusing on exploring the black holes.
