Dr. Alexandra Amon explaining how her research into the understanding of the Dark Universe, is facilitated by using a tool called ‘weak gravitational lensing’ at New Scientist Live 2022


Dr. Alexandra Amon is a cosmologist based at Cambridge University and Trinity College as a Senior Kavli Fellow. Her research focuses on understanding the Dark Universe, primarily using a tool called ‘weak gravitational lensing’. After growing up in Trinidad and Tobago, Dr. Amon studied at the University of Edinburgh, with her doctorate thesis winning the Royal Astronomical Society Michael Penston Thesis Prize for the best PhD in the field. Afterwards, she was a research fellow at Stanford University and at present, she coordinates the lensing team from the Dark Energy Survey - a large international collaboration. I am interested in cosmology: understanding structure formation, dark matter and dark energy and the intersection with galaxy formation. It is an exciting time to be an observational cosmologist, and my research uses the beautiful imaging from DES and KiDS lensing surveys, spectroscopic data from BOSS and now DESI and CMB information from Advanced ACT. My primary research focus weak gravitational lensing which probes the expansion history and growth of cosmic structures. In particular, I focus on tackling the main systematics in those analyses: estimating photometric redshifts, calibrating the shear of galaxies, modelling galaxies' intrinsic alignments, and the impact of baryonic feedback - ahead of Rubin Observatory.
