Abstract
Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

| PI Contribution | The UKRI funding has enabled Cambridge and the other UK partners to make a major contribution to the data management for the Simons Observatory project. |
| Collaborator Contribution | Cambridge will be leading on assessing the science readiness of frequency maps for lensing analysis and will be making major contributions to the development of instrumental and astrophysical simulations. Our current focus is on preparing software pipelines for lensing analysis of the initial science observations from the large-aperture telescope, including null tests that will be informative about the performance of the instrument and help with optimisation of the full science surveys. We are also working on investigating the expected impact of instrumental systematic effects in the Simons Observatory surveys on lensing science. We are developing a suite of simulated maps with systematic effects injected and will analyse these with the same software to be applied to the real data. |
