Description
Ultra high energy photons and neutrinos are carriers of very important
astrophysical information. They may be produced at the sites of cosmic
ray acceleration or during the propagation of the cosmic rays in the
intergalactic medium. In contrast to charged cosmic rays, photon and
neutrino arrival directions point to the production site because they
are not deflected by the magnetic fields of the Galaxy or the
intergalactic medium. In this work we study the characteristics of the
longitudinal development of showers initiated by photons and neutrinos
at the highest energies. These studies are relevant for development of
techniques for neutrino and photon identification by the JEM-EUSO
telescope. In particular, we study the possibility of observing the
multi-peak structure of very deep horizontal neutrino showers with
JEM-EUSO. We also discuss the possibility to determine the flavor
content of the incident neutrino flux by taking advantage of the
different characteristics of the longitudinal profiles generated by
different type of neutrinos. This is of grate importance for the study
of the fundamental properties of neutrinos at the highest energies.
Regarding photons, we discuss the detectability of the cosmogenic
component by JEM-EUSO and also estimate the expected upper limits on the
photon fraction which can be obtained from the future JEM-EUSO data for
the case in which there are no photons in the samples.

Minor Bodies of the Solar System
This project studies the physical and compositional properties of the so-called minor bodies of the Solar System, that includes asteroids, icy objects, and comets. Of special interest are the trans-neptunian objects (TNOs), including those considered the most distant objects detected so far (Extreme-TNOs or ETNOs); the comets and the comet-asteroid
