Profile/About Me

I am an Astrophysicist with strong interests in astro-particle physics and cosmology. My interests lie in the evolution of super-massive black holes and galaxies, the generation of truly diffuse backgrounds (from infrared to gamma rays), high-energy transients and high-energy sources in general. Recently I turned my attention to the evolution of the extragalactic background light and the role of the first stars during the epoch of re-ionization. I work with a number of instruments and telescopes both from the ground and in space, but my all-time favorites are the NASA missions Fermi, Swift, and NuSTAR.

Research Interests

Dr. Ajello’s research focuses on current topics of high-energy astrophysics, cosmology and astro-particle physics. There is a lot to be discovered about our Universe and even more about the most extreme environments in the Universe, where nature harnesses energies far beyond anything possible on Earth. Cosmology, particle physics, high-energy astrophysics and gravitational physics have tremendously progressed in the last decade. The intense research activities taking place at the cross road of these disciplines are enhanced by the opportunities that new facilities have opened up. Our group uses the Fermi gamma-ray space telescope, NuSTAR (the nuclear spectroscopic telescope array), and the Swift satellite (and many others) to unveil the mystery behind some of nature’s most powerful phenomena.

Research Group (Lab)

Dr. Ajello's lab comprises several postdoctoral fellows, graduate and undergraduate students. The group has access to several ground- and space-based observing facilities as well as the Palmetto cluster. The group collaborates with scientists at Stanford University, the Naval Research Laboratory, NASA's Goddard Space Flight Center, the Complutense University of Madrid and several other international institutions.
