Cosmology is at a tipping point – we may be on the verge of discovering new physics

Andreea Font is a Reader in Theoretical Astrophysics, Liverpool John Moores University.

“I am a theoretical cosmologist and my interests are in the formation and evolution of galaxies, in particular in the formation of our own galaxy, the Milky Way. To this aim, I build computer simulations that follow the evolution of Milky Way-type galaxies since their birth until the present time.
I am particularly interested in making detailed comparisons between cosmological simulations of the Milky Way and the most up-to-date observational data in our Galaxy, for example, the data obtained from the Gaia satellite. Examples of my recent work include modelling of stellar haloes of Milky Way-type galaxies and of satellite dwarf galaxies orbiting these systems.
I also have an interest in deciphering the nature of dark matter and, to this aim, I develop models that help us distinguish between various possible dark matter particle candidates using cosmological simulations.”

‘Cosmic inflation’: did the early cosmos balloon in size? A mirror universe going backwards in time may be a simpler explanation

Neil Turok is the inaugural Higgs Chair of Theoretical Physics at the University of Edinburgh. He holds the Roger Penrose Visiting Professorship at Perimeter Institute for Theoretical Physics in Canada where he is emeritus Director. Before that he was Chair of Mathematical Physics at Cambridge and Professor of Physics at Princeton.
Neil’s day job is developing and testing fundamental physics theories of the universe. His first-principles predictions of correlations between the temperature and polarisation of the cosmic background radiation (CBR), and the CBR and the galaxy distribution have been confirmed at high precision. His work also ruled out several popular theoretical models. Recently, he showed how a CPT-symmetric universe could provide the simplest-yet explanation of the cosmic dark matter, the large scale properties of the universe and the primordial density variations.

In 2008 Neil won the TED prize for his research and for AIMS. In 2016 he was made an Honorary Fellow of the UK Institute of Physics and was awarded the John Torrence Tate Medal of the American Institute of Physics for International Leadership in Physics. In 2018 he was appointed an Officer of the Order of Canada.
