Cosmic Rays
These high-energy particles constantly bombarding the Earth, remain mysterious in many aspects. They are believed to be messengers of the highest energy events of the Galaxy and beyond, but the details of their production and transport to the Earth are still debated. In light of the latest experimental cosmic-ray data, we seek new insights on these issues and their consequences on exotic physics.
Gamma Rays
Photons at the highest energies, above the Megaelectronvolt scale, are unique probes of the non-thermal processes in the universe and our Galaxy. We use high-energy gamma rays to study astrophysical emission processes from Galactic and extra-galactic sources, as well as get an insight into more exotic processes from, for example, dark matter.
Multimessenger
Exploring high-energy emission processes with a multi-messenger and multi-wavelength approach has proved essential to deepen our understanding of the universe.
We exploit this multipronged approach to study the physics of Galactic compact objects such as pulsars, but also dark matter, and other exotic particles.
Cosmology
We are interested in the dynamics of the early Universe, from the calculation of primordial nucleosynthesis and primordial neutrino observables for precision cosmology to the production of all sorts of exotic relics, from weakly interacting particles to primordial black holes, that could be candidates for the dark matter or explain other puzzling observations in the present-day Universe.
Gravitational Waves
The direct detection of gravitational waves has opened up a new astrophysical window. We are beginning to explore the potential of this new tool to address some current mysteries: Can they help us understand still unidentified astrophysical sources? Can we unveil new types of sources, perhaps of exotic origin and from the early Universe? What is the potential of forthcoming detectors?
Tools
To tackle these challenging questions in astrophysics, we use databases, devise codes in multiple languages, and run them on our local computational center. Helpful information and links in this regard can be found here.
