Our results extend the parameter space of gravity measurements to small, single source masses and low gravitational field strengths. Further improvements to our methodology will enable the isolation of gravity as a coupling force for objects below the Planck mass. This work opens the way to the ...
to make our model parameter-free, we need to fix the value of the constant mean appearing in Eq. (9). The original finding in the context of string theory concerning the magnitude ofβbeing of order unity has since been confirmed by a large body of works starting from different frameworks...
Given that the Hubble parameter H2α Gρα GT4, the creation of light elements at early times (and high temperatures T) depends on Newton's constant. The comparison between theoretical predictions and observations of the abundance of light elements typically constrains the value of G at the ...
Each parameter is perturbed with a random value within the tolerance range for each variable. The distribution of the 1000 simulation results is shown in Figure 15. Within the science FOV, most of the perturbation results are less than λ/30. Statistical analysis of the simulation data shows ...

A2parameterThe Yarkovsky effect is one of the noticeable factors in the orbital evolution of near-Earth asteroids (NEAs). The A 2 non-gravitational parameter describes the corresponding acceleration in the NEA motion model. This parameter can be derived from astrometric observations of the NEA. We...
It reaches a peak and then goes down to the value <1<1. The bias caused by gravitational lensing on the luminous distance can be seen from the bottom figure. The picture is from ref. [75].3.2 波动光学效应在上一节, 我们在引力透镜计算过程中采用几何光学近似. 事实上, 几何光学近似在大...
When we analyse gravitational-wave data to infer the source properties (location, masses, etc.), wemap out parameter spacewith a set of samples: a list of points in the parameter space, with there being more around more probable locations and fewer in less probable locations. These samples en...
We propose measurements within an orbiting satellite which would improve the accuracy of $G$ by two orders of magnitude and also place new upper limits on the field-strength parameter $\\ensuremath{\\alpha}$ of any Yukawa-type force, assuming a null result. Preliminary analysis indicates that...
In Fig. 1a, the chirality control parameter is set to be zero (no gyroscopic coupling), and the wave of the same polarisation, characterised by the deflection in the (x, z)-plane moves along the z-axis. In part (b) of the same figure, where \(\beta =2\), the gyroscopic chirality...
