High energy radiation from black holes
WebFirstly, in order to get the power level needed, the BH would have to be "subatomic black hole" (SBH), with a radius less than 10 − 10 m. Apparently, we don't know exactly how much power a given mass SBH would emit, that requires basically quantum gravity physics models, and those are not completely decided upon. Webtechniques, instrumentation, and observational methods astronomers use to study high-energy radiation from space. The Probes of Multimessenger Astrophysics - Maurizio …

Web11 de abr. de 2024 · X-ray binaries, as bright local sources with short variability timescales for a wide range of accretion processes, represent ideal targets for high-resolution X-ray spectroscopy. In this chapter, we present a high-resolution X-ray spectral perspective on X-ray binaries, focusing on black holes and neutron stars. The majority of the chapter is … WebMagnetic Penrose process (MPP) is not only the most exciting and fascinating process mining the rotational energy of black hole but it is also the favored astrophysically viable …
Web9 de jul. de 2024 · Instead, black holes are decaying, and losing mass over time, because the energy emitted by this Hawking radiation is slowly reducing the curvature of space in that region. Once enough time... Web25 de mar. de 2024 · Using this we compute the entropy of Hawking radiation and argue that it follows the Page curve, as suggested by recent computations of the entropy and entanglement wedges for old black holes. The higher-dimensional geometry connects the radiation to the black hole interior in the spirit of ER=EPR.
