I. Sakalli, O. A. Aslan

摘要:

本文研究了四维黑洞上非渐近平坦(NAF)旋转线性微扰(RLDBH)的标量扰动。我们表明,径向和角波方程可以解决的超几何函数。精确的灰体因子(GF),吸收截面(ACS),和衰减率(DR)的无质量标量波计算这些黑洞(BH)。ACS和DR获得的结果进行了讨论,通过图表。

英文摘要:

We analytically study the scalar perturbation of non-asymptotically flat (NAF) rotating linear dilaton black holes (RLDBHs) in 4-dimensions. We show that both radial and angular wave equations can be solved in terms of the hypergeometric functions. The exact greybody factor (GF), the absorption cross-section (ACS), and the decay rate (DR) for the massless scalar waves are computed for these black holes (BHs). The results obtained for ACS and DR are discussed through graphs.
