The first detection of gravitational waves (GWs) produced by the binary neutron star (BNS) merger in August 17, 2017[1] is fairly meaningful because it initiated the new era of multi-messenger astronomy. In this BNS merger event, we not only detected the gravitational waves.Xin Zhang中国科学...
We develop a new method, based on a Fourier decomposition of the time-dependent, LISA-modulated gravitational-wave signal, to study this intricate problem. The method is faster than standard Monte Carlo simulations by orders of magnitude. By surveying the parameter space of potential LISA sources,...
And the best fitted values of EM compilation, which correspond to the minimum of sum of \chi ^{2}_{PantheonPlus}, \chi ^{2}_{CC} and \chi ^{2}_{DESI}, is used as fiducial parameter values in standard siren simulations. Meanwhile, the strain h(t) in the gravitational wave ...
The fitted SN model parameters arex1 = 1.083 ± 0.094 andc = −0.007 ± 0.007. The lack of colour excess confirms that differential extinction is negligible. Since the lightcurve parameter errors do not include the model covariance, we conservatively add the SALT2 model...
At the same time, as shown here, this setup predicts a typical expected value of the strong-CP parameter in QCD of theta approximately 10(-9). This strongly motivates a more sensitive measurement of the neutron electric dipole moment.
(2.15). Thus, it can be explicitly broken by the gravitational effect. 2.2 The symmetry breaking pattern It was first pointed out in ref. [29] that the Higgs representations are responsible for the gauge symmetry breaking patterns, as well as the proper choices of the Higgs self couplings. ...
In the second scenario, we consider the Randall-Sundrum type II model. We show that the lower bound of the five-dimensional Planck scale in this model, which is determined from the validity of Newtonian gravitational potential at small distance, turns out to be crucial in eliminating this ...
[281,282]. Inflation, see Sect.3.3, can not offer a solution if the distribution of high-entropy gravitational remnants from big-bang is scale-invariant as one could expect [281]. This leads to the question of whether ‘the initial conditions of the universe could have originated from a ...
compact binary system encodes the information ofdL, providing an access to the direct measurement ofdL, the crucial parameter we use in this paper. We sense the possibility and potential from detecting gravitational wave. The detection of GW not only conforms to the general relativity, but also ...
