Effect of Scalar Mass in the Absorption and Emission Spectra of Schwarzschild Black Hole

, 2004
Following Sanchez's approach we investigate the effect of scalar mass in the absorption and emission problems of 4d Schwarzschild black hole. The absorption cross sections for arbitrary angular momentum of the scalar field are computed numerically in the

Absorption cross section in Lifshitz black hole

, 2012
We derive the absorption cross section of a minimally coupled scalar in the Lifshitz black hole obtained from the new massive gravity. The absorption cross section reduces to the horizon area in the low energy and massless limit of s-wave mode ...

Absorption by Extremal D3-branes [PDF]

, 2000
The absorption in the extremal D3-brane background is studied for a class of massless fields whose linear perturbations leave the ten-dimensional background metric unperturbed, as well as the minimally-coupled massive scalar.
