Durham astrophysicists’ key contributions to cosmic discoveries

Published:

Recommended citation: "These observations are tremendously exciting: they demonstrate the capabilities of this precision instrument, while already pushing the cutting-edge in astrophysics. Among the results, it is astonishing that Euclid has already discovered 500 gravitational lens candidates substantially adding to the total of approximately 1,000 previously known lensed galaxies, which took over 40 years to discover! At this rate, Euclid is expected to observe 200,000 such objects over six years of the survey. These observations, together with the two billion galaxies Euclid will image, will help us understand how dark matter is distributed in the Universe and may allow us to uncover its nature.

Final findings from Kilo-Degree survey confirm cosmology model

Published:

Recommended citation: "The Kilo-Degree Survey has said its last word on one of the most polarising tensions in cosmology! The final KiDS results reconcile early- and late-Universe measurements of the distribution of dark matter in the Universe. As we enter the golden era of gravitational lensing with surveys such as Euclid, this analysis drives the state-of-the-art of weak lensing cosmology and teaches us important lessons for the future." - MvWK https://www.durham.ac.uk/news-events/latest-news/2025/03/final-findings-from-kilo-degree-survey-confirm-cosmology-model/

Workshops for the “Theoretical Physics 2” course

Tutorial, Durham University, Department of Physics, 2024

Convening and demonstrating of two weekly workshops as part of the 2nd-year undergraduate course “Theoretical Physics 2” (PHYS2631) over two terms. The course covers calculus of varations, Lagrangian and Hamiltonian mechanics, symmetry principles and advanced quantum theory. Each workshop involves demonstrating a problem set to approx. 40 students, and present the answers to the questions.
