“…The two main applications of these potentials is the computation of quasi-normal modes and Hawking radiation. The latter will be the subject of the companion paper [42], which will tackle the in-depth computation of Hawking radiation for modified gravity black holes in order to identify critical differences with the emission by a standard Schwarzschild black hole.…”

“…Interesting metrics which are not tr-symmetric arise in loop quantum gravity, where effective semi-classical corrections due to effects of quantum gravity have been derived and give rise to so-called polymerized BHs. There are many proposals for deriving such BH metrics [18,19,21,[46][47][48][49], as we will review in the companion paper [42]. Here, for the sake of the example and in order to compare with previous results obtained in [39,41], we will focus on the particular type of polymerized BHs with [50] Here a 0 is the area gap of loop quantum gravity, and the radii are given by…”

In the context of the dynamics and stability of black holes in modified theories of gravity, we derive the Teukolsky equations for massless fields of all spins in general spherically-symmetric and static metrics. We then compute the short-ranged potentials associated with the radial dynamics of spin 1 and spin 1/2 fields, thereby completing the existing literature on spin 0 and 2. These potentials are crucial for the computation of Hawking radiation and quasi-normal modes emitted by black holes. In addition to the Schwarzschild metric, we apply these results and give the explicit formulas for the radial potentials in the case of charged (Reissner-Nordström) black holes, higher-dimensional black holes, and polymerized black holes arising from loop quantum gravity. The phenomenological applications of these formulas will be the subject of a companion paper. CONTENTS

We present the new version v2.0 of the public code BlackHawk designed to compute the Hawking radiation of black holes, with both primary and hadronized spectra. This new version aims at opening an avenue toward physics beyond the Standard Model (BSM) in Hawking radiation. Several major additions have been made since version v1.0: dark matter/dark radiation emission, spin 3/2 greybody factors, scripts for cosmological studies, BSM black hole metrics with their associated greybody factors and a careful treatment of the low energy showering of secondary particles; as well as bug corrections. We present, in each case, examples of the new capabilities of BlackHawk.

Quantum atmosphere effective radii for different spin fields from quantum gravity inspired black holes

Quantum atmosphere effective radii for the emission of spin-0, 1/2, 1, and 2 massless fields from Schwarzschild, Tangherlini, non-commutative geometry inspired, and polymeric black holes are calculated. The power observed from the black hole at spatial infinity taking greybody factors into account is compared to an equal-power black-body radiator of the same temperature but different effective radius. A large range of different radii are obtained for different spin fields and black holes. The equal-power black-body effective radius is not, in general, a good proxy for the location of the quantum atmosphere.
