Albino Perego
I am a theoretical physicist and nuclear astrophysicist, presently working for the Istituto Nazionale di Fisica Nucleare (INFN), Sezione di Milano Bicocca e Gruppo Collegato di Parma.

My research interests span a broad range of timely and fascinating topics, including stellar explosions of massive stars (core-collapse supernovae), the coalescence of neutrons star binaries, and the production of the heavy elements in the Universe.

My major focus is the role of weak interactions in high-energy astrophysics. I also develop computational methods and codes to study the behavior of neutrinos in dense and hot matter.

My research interests

Theoretical and nuclear astrophysics, neutrino astrophysics, multimessenger astrophysics, gravitational waves, core-collapse supernovae, neutron star mergers, computational astrophysics.

Binary Neutron Star Merger

The merger of two neutron stars bound in binary system is a remarkable consequence of the emission of gravitational waves by accelerated masses and one of the most spectacular consequences of the Theory of General Relativity. I have studied the role of weak interactions and neutrinos during the colaescence of two neutron star in one of such mergers. These events, in addition to the emission of gravitational waves, produce copius amounts of neutrinos of all flavor. The production and theabsorption of electron type neutrinos and anti-neutrinos influence significantly the composition of the ejected matter. This determines the subsequent r-process nucleosynthesis and the electromagnetic emission powered by the radioactive decay of the newly produced nuclei (kilonova emission). Recently, I joined the CoRe (Computational Relativity) collaboration and together we have studied the luminosity in gravitational waves of binary neutron star mergers. We have recently released the largest up-to-date gravitational wave waveforms catalogue http://www.computational-relativity.org/. I am also part of the Virgo and ENGRAVE international collaborations to study both the gravitational wave and electromagnetic emissions coming from compact binary mergers.

Core-Collapse Supernovae

Core-collapse Supernovae are among the most violent and spectacular explosions in the Universe, marking the end of the life of a massive star. On the one hand they produce black holes and neutron stars in their center. On the other hand, the explosion expells into space a large portion of the progenitor star. This ejecta is one of the major sources of new elements, contributing to the chemical evolution of the Universe. During my studies, I developed a physically motivated and computationally inexpensive treatment for neutrinos and weak reactions in multi-dimensional astrophysical simulations. Its first application was the study of the magneto-rotationally driven explosion of a fast rotating, magnetized iron core in 3D. In a large collaboration, we developed a novel parametrized model to explode stars in spherical symmetry to study the explosive nucleosynthesis of a wide set of progenitors including the effect of neutrinos.
