Theoretical Cosmology: Dark Energy and Modified Gravity

Theoretical cosmology studies the dynamics, origin, evolution, and fate of the universe, and the formation of structures (galaxies, galaxy clusters, and superclusters) in it. In 1998 it was discovered, by studying distant supernovae, that the expansion of the universe is accelerated. Many theoretical models have been proposed in order to explain this shocking discovery and they mostly fall into two classes: dark energy and modified gravity. Dark energy models assume that Einstein’s theory of gravity (general relativity) is valid and that a mysterious form of dark energy of unknown nature permeates the universe and makes up 70% of its energy content. This dark energy must necessarily have exotic properties, such as a negative pressure. The current observational data seem to require an even more negative pressure and more exotic energy (called phantom energy), which may cause the universe to end at a finite time in the future in a Big Rip singularity (the end of time), in which all bound objects-galaxies, planets, humans, atoms-are ripped apart by increasing gravitational forces. If phantom energy is really fuelling the cosmic acceleration, we probably have to abandon Einstein’s general relativity in favour of alternative gravity theories such as, for example, scalar-tensor gravity, a generalization of Einstein’s theory.

The second class of models, modified gravity, does not require exotic dark energy but instead modifies Einstein’s relativity with corrections that only affect large (cosmological) scales.

Dr. Faraoni’s research explores both classes of models, trying to fully understand their dynamics, explain the cosmic acceleration, develop models that are theoretically consistent and compatible with available experiments, study their predictions (e.g., will the universe accelerate forever? Will it end in a Big Rip?) and related issues such as the production of gravitational waves, or the accretion of phantom energy onto black holes or wormholes. Long term goals include the development of the correct theory of gravity (it is possible that departures from Einstein’s gravity are unobservable at the small Solar System scales but are already observed in the cosmic acceleration), finding out if dark energy actually exists and, if so, determining precisely its strange properties, understanding the early universe and obtaining information, otherwise inaccessible on Earth, on the high energy physics that left an imprint in the cosmic microwave background and in the distribution of galaxies and galaxy clusters.

Other interests include the study of black holes embedded in a cosmological background, foundations and possible violations of the Equivalence Principle (the basis of relativistic gravity) in high energy physics, and the thermodynamics of spacetime.

Dr. Faraoni collaborates with many researchers worldwide on the subjects above.

Dr. Lorne Nelson

Full Professor

Professor Nelson received his Ph.D. in 1984 in the area of theoretical astrophysics (cannibalistic binary interactions). He subsequently held a postdoctoral fellowship at MIT (Center for Space Research) that led to pioneering work on the structure and evolution of a completely new class of substellar objects known as Brown Dwarfs.

From 1986-1988 he was a research fellow at CITA (Canadian Institute of Theoretical Astrophysics). He joined the department of physics at Bishop’s as an Assistant Professor in 1988 and became a Full Professor in 1998. In 1995 he won the Chancellor’s Prize for teaching and he is currently a Canada Research Chair in Astrophysics.

Dr. Jason Rowe

Full Professor, Canada Research Chair in Exoplanet Astrophysics

Dr. Jason Rowe received his PhD at the University of British Columbia for his work on measuring the reflectively of extra-solar planets using photometric measurements from the Canadian MOST Satellite. After his PhD Dr. Rowe joined the Kepler team as a NASA Postdoctoral Fellow contributing towards the first Kepler discoveries and was awarded the NASA Exceptional Scientific Achievement medal for his work on measuring fundamental parameters of exoplanets.

Dr. Rowe is currently recruiting Undergraduate and Graduate students.

Dr. Rowe then joined the SETI Institute as a research scientist and member of Kepler Science office and his continued work on exoplanets lead to the discovery of Earth-sized planets in the habitable zone of main-sequence stars and bulk validation of 812 extrasolar planets. During his tenure at SETI he was awarded his second NASA Exceptional Scientific Achievement medal. Dr. Rowe then joined the JWST NIRISS Instrument team at Université de Montréal to develop techniques and tools to measure the atmospheres on extrasolar planets. Dr. Rowe is now a Canada Research Chair in Exoplanet Astrophysics, his current research goals are to determine what properties make a planet ‘Earth-like’ and whether there is life beyond Earth. He has authored and co-authored over 200 publications with over 16000 total citations.

Dr. John Ruan

Associate Professor, Canada Research Chair in Multi-Messenger Astrophysics

Dr. John Ruan received his PhD at the University of Washington, and was then a postdoctoral fellow at McGill University, before joining the faculty at Bishop’s. Dr. Ruan is an observational astronomer with research interests in nucleosynthesis of the heaviest elements, black hole accretion, and cosmology.
