Orfeu Bertolami

Orfeu Bertolami is a theoretical physicist who works in problems of astrophysics, cosmology, general relativity, and quantum gravity. He worked at Instituto Superior Técnico in Lisbon, Portugal from 1991 to 2010. He is currently professor at Departamento de Física e Astronomia of the Faculdade de Ciências da Universidade do Porto.

In particular, Bertolami studied baryogenesis, the cosmological constant problem and its connection with the equivalence principle, the generalized Chaplygin gas model of unification of Dark Energy (to explain the cosmic acceleration) and Dark Matter (to explain the flattening of the rotation curves of galaxies) and some Modified models of gravity with non-minimal coupling between curvature and matter. He has also worked on the Pioneer Anomaly, which was shown to be most likely due to onboard thermal effects and reflection of the generated radiation. Most recent work concerns extensions of quantum mechanics based on phase-space noncommutativity

Dark Matter Meets Einstein’s Equivalence Principle: A Tale Of Two Particles

Dark matter is one of the most puzzling challenges of present-day physics. It is a mysterious entity that presents itself only through the gravitational interaction and corresponds to about 27% of the energy content of the Universe at present. Its […]

Using Physics To Capture The Changes To The Earth System In The Anthropocene

The Anthropocene represents an entirely new epoch in the history of the Earth System. Evidence shows that the evolution of Earth is now determined mostly by the influence of human activities, rather than the natural astronomical and geophysical forces, q, […]
