![]() ![]() ![]() Generally, it is very difficult because that it is not easy to get a solution for the gravitational wave around a black hole since the Einstein equation with perturbation is very complicated. Since both the gravitational waves detection and Event Horizon Telescope observation play a vital role in the study of black holes and verification of various gravity theories, it is very interesting to study the effects of gravitational waves on black hole shadows. These could provide some theoretical templates for the future astronomical observations announced by Event Horizon Telescope and BlackHoleCam. The black hole shadows with other parameters in various theories of gravity have been recently investigated in Refs. These novel structures in shadows are found to be caused by non-integrable photon motions. Especially, the self-similar fractal structures are found in shadow for a rotating black hole with scalar hair, a Majumdar–Papapetrou binary black hole system, Bonnor black diholes with magnetic dipole moment, and a non-Kerr rotating compact object with quadrupole mass moment. In the spacetime of a Kerr black hole with Proca hair and a Konoplya–Zhidenko rotating non-Kerr black hole, the cusp silhouette of black hole shadows emerge in certain range of parameter. But for a Kerr black hole, shadow becomes a D-shaped silhouette gradually with the increase of spin parameter. For example, the shadow of a Schwarzschild black hole is a perfect black disk. The fingerprints of the geometry around the black hole would be reflected in the shape and size of black hole shadow. The dark region in the center of black hole image is black hole shadow, which corresponds to light rays fall into event horizon of black hole. The initial analyses of the first image of black hole have no striking deviations from the predictions of general theory of relativity. Black hole image can be regarded as a potential tool to verify gravity theories and identify black hole parameters. It provides the first direct visual evidence that there exists exactly black hole in our Universe. The detection of gravitational waves could help us to understand black hole further and to verify various gravity theories.Īnother exciting event in astrophysics and black hole physics is the first image of the supermassive black hole in the center of the giant elliptical galaxy M87, which was announced by Event Horizon Telescope (EHT) Collaboration in 2019. By comparing with theoretical templates, gravitational waves could tell us a variety of parameters of astrophysical compact objects such as their masses, spins and so on. Especially, the discovery of the electromagnetic signals in gamma-ray arising from binary neutron star (BNS) merger means the arrival of multi-messengers astronomy. ![]() Subsequently, there are several gravitational waves events have been detected, which are caused by binary black hole merger or by binary neutron star merger. Plants vs.The first direct observation of gravitational waves (GW150914) reported by LIGO and Virgo Scientific not only confirms the success of Einstein’s general relativity, but also opens a new era in the fields of astronomy, astrophysics and cosmology.Pillars of Eternity 2: Deadfire - Ultimate Edition.PAW Patrol The Movie: Adventure City Calls.PAW Patrol Mighty Pups Save Adventure Bay.Ori and the Blind Forest: Definitive Edition.Opus: Echo of Starsong – Full Bloom Edition.Ni no Kuni: Wrath of the White Witch Remastered.JoJo’s Bizarre Adventure All-Star Battle R.Hot Wheels Unleashed – Game of the Year Edition.Five Nights at Freddy's: Original Series.eFootball PES 2012 SEASON UPDATE STANDARD EDITION.Disney Dreamlight Valley: Founder’s Edition.DC League of Super-Pets: The Adventures of Krypto and Ace.Coffee Talk Episode 2: Hibiscus & Butterfly.BlazBlue: Cross Tag Battle Special Edition.ARK: Survival Evolved Explorer's Edition.Xbox Game Pass games list for Xbox consoles Lawn Mowing Simulator (Console, PC and Cloud).Evil Genius 2: World Domination (Console, PC and Cloud).This list will be updated at the beginning and the halfway point of every month, with more titles announced for removal.
