The absorption cross section for the warped AdS3 black hole background shows that it is larger than the area
even if the s-wave limit is considered. It raises some question whether the deviation from the areal cross
section is due to the warped configuration of the geometry or the rotating co- ordinate system, where these
two effects are mixed up in the warped AdS3 black hole. So, we study the low-frequency scattering dynamics of
propagating scalar fields under the warped AdS3 background at the critical point which reduces to the BTZ black
hole in the rotating frame without the warped factor, which shows that the deformation effect at the critical
point does not appear.
