Seminar

"The separate universe approach in multifield inflation models"

Hugo Holland is a second year PhD student in Institut d'Astrophysique Spatiale in Orsay (just south of Paris). He works with Julien Grain on stochastic inflation and all things related. Before his PhD, Hugo graduated from Ecole Polytechnique in France and got his masters degree in theoretical physics at King's College London, where he worked on eternal inflation with Eleni Alexandra Kontou.

"Measuring and modelling galaxy intrinsic alignment"

Dr Danielle Leonard is a Lecturer at the School of Mathematics, Statistics and Physics at Newcastle University. Their research focuses on late-time observational cosmology, particularly weak lensing and photometric galaxy clustering. They work both on understanding systematic effects which impact weak gravitational lensing measurements such as intrinsic alignment and photometric redshift uncertainties, and on methods for best constraining beyond-standard cosmological models with observational data.

Nathan J. Carlson is a PhD candidate at the University of Toronto and the Canadian Institute for Theoretical Astrophysics (CITA). Nathan’s work in theoretical cosmology focusses on linking early universe physics to large-scale structure of the universe as we see it today.

“Diving into the era of Large-Scale Structure data: going beyond the Standard Cosmological Model”

Guadalupe is a Theoretical Cosmologist investigating the Universe's origins, evolution, and ultimate fate by studying alternative cosmological models with cutting-edge astrophysical data and advanced statistical techniques, while also forecasting the potential of new experiments and observables, such as Gravitational Waves.

Raphael is a post doc at Carnegie Mellon University, working on the the clustering properties of dark matter on galactic scales, with a particular focus on the tidal evolution of dwarf spheroidal galaxies. He builds dynamical models to contrast observational data against competing theories of dark matter.

"The status and scientific promise of the Thirty Meter Telescope"

"Galaxy clusters as the Universe’s largest particle accelerators"

Dr. Erik Osinga is a postdoctoral fellow at the Dunlap Institute. He completed his PhD at Leiden University in 2023. Erik's work centres on understanding how magnetic fields and particle acceleration shape the environments within and around galaxy clusters.

"The Evolution of Galaxies as Told through Their Globular Cluster Systems"

Veronika Dornan is a final-year PhD candidate in the Department of Physics and Astronomy at McMaster University. Her research uses observations of galaxies' globular star cluster systems as tracers of their evolutionary histories. She is particularly interested in studying the globular cluster system mass - halo mass scaling relation and understanding what drives this relation from dwarf galaxies to massive ellipticals galaxies.

Eduardo Martín-Martínez is a Full Professor in the Department of Applied Mathematics at the University of Waterloo. He is also an Institute for Quantum Computing (IQC) Associate, a Perimeter Institute Affiliate and a member of the Waterloo Centre for Astrophysics. Since July 2022, he has served as the Chair of the International Society for Relativistic Quantum Information.

"Evidence for Photospheric Absorption Lines in the X-ray Spectrum of the Neutron Star in Puppis A"
