3 Sep 2019 | | Abstract: | In this work we study black hole area quantization in the context of
gravitational wave physics. It was recently argued that black hole area
quantization could be a mechanism to produce so-called echoes as well as
characteristic absorption lines in gravitational wave observations of merging
black holes. One can match the spontaneous decay of these quantum black holes
to Hawking radiation calculations. Using some assumptions one can then estimate
the natural widths of these states. As can be seen from a classical paper by
Bekenstein and Mukhanov the ratio between width and spacing of non-spinning
black hole states approaches a small constant, which seems to confirm the
claim. However, we find that including the effect of black hole spin, the
natural widths increase. To properly address any claim about astrophysical
black holes one should examine the spinning case, as real black holes spin.
Thus the word "spinning" is key to the question of whether or not black holes
should have an observable spectrum in nature. Our results suggest that it
should be possible to distinguish between any scenarios for which the answer to
this question is yes. However, for all of the commonly discussed scenarios, our
answer is emph{almost certainly no}. | | Source: | arXiv, 1909.1254 | | Services: | Forum | Review | PDF | Favorites | |
