论文摘要
最近，Vagnozzi和Visinelli的作品[Phys。 Rev. D 100，024020（2020）]表明，M87*的阴影建立了$ L \ Lessim 170 $ au的上限，其中$ l $是ADS $ _5 $ curvature Radius，1 Au是一个天文学单位。另一方面，事件地平线望远镜捕获了射手座A*（sgra*）阴影的第一张图像，这是与超质量黑洞相关的银河中心源。在本文中，我们有动力全面探索$ l $的新上限，并带有Sgra*的阴影，发现$ l \ lyssim 0.097 $ au。我们的结果提高了三个数量级的精度。这也是对sgra*阴影显着的第一张图像的外来物理学的第一个可量化限制之一。
Recently, Vagnozzi and Visinelli's work [Phys. Rev. D 100, 024020 (2020)] reveals that M87*'s shadow establishes an upper limit of $l \lesssim 170$ AU, where $l$ is the AdS$_5$ curvature radius and 1 AU is one astronomical unit. The Event Horizon Telescope, on the other hand, just captured the first image of the shadow of Sagittarius A* (SgrA*), the Galactic center source associated with a supermassive black hole. In this paper, we are motivated to comprehensively explore a new upper limit of $l$ with the shadow of SgrA*, and the findings suggest that $l \lesssim 0.097$ AU. Our results improve accuracy by three orders of magnitude. This is also one of the first quantifiable limitations on exotic physics derived from the remarkable first image of the shadow of SgrA*.
