Alessandro Mirizzi

INFN Sezione di Bari is offering a two-year postdoctoral fellowship in theoretical astroparticle physics focused on astrophysical probes of novel Weakly Interacting Slim Particles (WISPs) . The project studies how WISPs such as axions, dark photons, and massive gravitons could be produced in and affect the physics of stars, supernovae, and neutron stars. The research is highly interdisciplinary, bringing together quantum field theory in high-temperature and high-density astrophysical environments, advanced stellar evolution simulations , and multi-messenger analyses involving photons, gamma rays, neutrinos, and gravitational waves. The scientific aim is to identify new observational signatures and test models of physics beyond the Standard Model through astrophysical data and theory. The fellowship is based in the theoretical astroparticle physics group in Bari , which includes Eligio Lisi , Antonio Marrone , Alessandro Mirizzi , and several PhD students. The position sits within the 2027/2028 INFN Fellowship Programme and is explicitly linked to Call No. 29216. This is a research-intensive postdoctoral opportunity for candidates interested in the interface of particle physics, astrophysics, and cosmology, with a strong emphasis on interpreting astrophysical environments as laboratories for new fundamental physics.
