TLDR
In this paper, a gradient index lens was used to mimic the Schwarzschild precession in the orbit of the star S2 near the Galactic Center massive black hole, which was recently first detected by European Southern Observatory.Abstract:
General relativity establishes the equality between matter-energy density and the Riemann curvature of spacetime. Therefore, light or matter will be bent or trapped when passing near the massive celestial objects, and Newton’s second law fails to explain it. The gravitational effect is not only extensively studied in astronomy but also attracts a great deal of interest in the field of optics. People have mimicked black holes, Einstein’s ring, and other fascinating effects in diverse optical systems. Here, with a gradient index lens, in the geometrical optics regime, we mimic the Schwarzschild precession in the orbit of the star S2 near the Galactic Center massive black hole, which was recently first detected by European Southern Observatory. We also find other series of gradient index lenses that can be used to mimic the possible Reissner–Nordstrom metric of Einstein’s field equation and dark matter particle motion. Light rays in such gradient lenses will be closed in some cases, while in other cases it would be trapped by the center or keep dancing around the center. Our work presents an efficient toy model to help investigate some complex celestial behaviors, which may require long period detection by using high-precision astronomical tools. The induced gradient lenses enlightened by the gravitational effect also enrich the family of absolute optical instruments for their selective closed trajectories.read more

The Observation of Gravitational Waves from a Binary Black Hole Merger
TL;DR: The first direct detection of gravitational waves and the first observation of a binary black hole merger were reported in this paper, with a false alarm rate estimated to be less than 1 event per 203,000 years, equivalent to a significance greater than 5.1σ.

Conformal optical black hole for cavity
TL;DR: In this paper , an optical black hole (OBH) cavity based on transformation optics is proposed and demonstrated, where the radiation loss of all WGMs in OBH cavity is completely inhibited by an infinite wide potential barrier, and the WGM field outside the cavity is revealed to follow $1/r^\alpha$ decay rule based on conformal mapping.

Theory of light propagation in arbitrary two-dimensional curved space
Chenni Xu,Li-Gang Wang +1 more
TL;DR: In this article, the Huygens-Fresnel principle was used to study light propagation along arbitrary geodesics on any 2D curved surfaces, such as a typical surface of revolution, Flamm's paraboloid, from which one can understand the behavior of light in the curved geometry of Schwarzschild black holes.
