MAGIC sensitivity to Primordial Black Hole bursts and modelization of BH chromospheres and gamma-ray emission spectra
In this work, I have approached two of the most important facets involved in the search for PBHs, namely the determination of the expected particle spectrum and the perspectives for detection with the present and future gamma-ray instruments. On the one hand, I have developed a toy model for black hole chromospheres that represents an extreme possibility that allows the determination of the systematic errors of models of PBH surroundings, rather than attempting to provide a realistic explanation. This model is based on the assumption that the quark-gluon plasma can be treated as an ultra-relativistic perfect fluid at thermal equilibrium and hence the black hole emission spectrum is expected to show a thermal profile. In the second part of this work, we estimate the MAGIC sensitivity to primordial black hole bursts by calculating the minimum detectable burst rate density. To do so, we adapt a method originally applied to Milagro and HAWC for MAGIC and afterwards we compare our results to theirs. As a final comment, we briefly discuss how CTA could perform in comparison to MAGIC and the other facilities. Despite having approached two major questions of this field, we have also seen that it is a very rich topic that provides lots of possible ways to carry out a continuation of this work.
