摘要:

我们研究了IIB型超弦/超引力激发时空中的五维黑洞的阴影行为,考虑了有无旋转的解。几何性质的形状和大小进行了分析的D3-膜数和旋转参数。具体地说,我们发现,形状确实显着扭曲,这些物理参数和阴影的大小与膜或“颜色”的数量和旋转减少。然后,我们研究几何可观量和能量发射率方面。

英文摘要:

We study the shadow behaviors of five dimensional (5D) black holes embedded in type IIB superstring/supergravity inspired spacetimes by considering solutions with and without rotations. Geometrical properties as shapes and sizes are analyzed in terms of the D3-brane number and the rotation parameter. Concretely, we find that the shapes are indeed significantly distorted by such physical parameters and the size of the shadows decreases with the brane or "color" number and the rotation. Then, we investigate geometrical observables and energy emission rate aspects.
