The quark-gluon plasma (QGP) formed in highly energetic particle
collisions, like those at RHIC and the LHC experiments, is a
strongly coupled system. Not only that, it is now widely accepted
that a very intense magnetic field is generated in non-central
collisions. Given that photons produced escape the plasma
essentially undisturbed, they are very appealing probes to
obtain information about the first stages of the plasma evolution.
The AdS/CFT correspondence has proven to be a useful tool for
studying the non-perturbative properties of this plasma, by means
of studying solutions of dual gravitational theories. In this
talk I will discuss one such gravitational model, and the results
regarding the emission of photons that we obtained.
