Assessing the systematic uncertainties influencing weak gravitational lensing of 21cm emission for galaxies
Lead Research Organisation:
Liverpool John Moores University
Department Name: Astrophysics Research Institute
Abstract
This will involve studies of cosmological hydrodynamical simulations, playing leading roles in the development of the state-of-the-art EAGLE and BAHAMAS suites. They will develop a broad range of algorithms aimed at the production of "sky maps" in a range of wavebands appropriate for the interpretation of key observables, to help interpret existing observational surveys and guide future observational strategies. These must be massively-parallel and capable of accommodating datasets comprising billions of resolution elements, each described by multiple variables. The student will have access to Tier-1 HPC facilities via membership of the Virgo Consortium for Cosmological Supercomputer Simulations and collaboration with the Hartree centre. A particularly interesting element of the necessary techniques, e.g. ray-tracing, is their suitably for parallelisation on new computational architectures. This element has already been investigated by LBDN researchers as a result of a similar issue being identified through work with the European Centre for Medium-term Weather Forecasting.

| Title | Morphologies and Orientations of Star-Forming Gas Distributions in EAGLE |
| Description | A database relating to the shapes and orientations of the star-forming gas in the EAGLE suite of cosmological simulations will be added to the publicly available database first outlined in McAlpine et al 2016. This will take place following the publication of two papers currently in preparation relating to this data. |

| PI Contribution | As part of my PhD scheme I am required to spend six months working in industry. For three of those months, I was based at imagin3d, a North-West England based company. Using skills acquired during my PhD, I assisted them in the development of augmented reality applications for use in astronomy themed education and outreach settings. |
| Collaborator Contribution | Their expertise in software packages such as Unity and Unreal engine facilitated large production of the above apps. Further, they provided me with the training to create my own outreach and educational augmented reality apps. |
| Impact | There is the potential for the commercialisation of the apps produced. Furthermore, there are promising links with academic partners which may lead to usage of the apps in events led by the National School's Observatory, but this is yet to take place. |

| Country | United Kingdom |
| Sector | Private |
| PI Contribution | Together with members of the Virgo Consortium, I am working to display cosmological simulations and high-performance computing at the Royal Astronomical Society's exhibition this year. I am working on one aspect of the display, aimed at retaining engagement through augmented reality representations of galaxies within simulations. |
| Collaborator Contribution | My partners are working on the main body of the display, aimed at obtaining the attention of attendees of the exhibition and educating them on the simulations in the first instance. |
| Impact | No outputs yet. |

| Description | Institute of Physics Three Minute Wonder - Merseyside Heat |
| Form Of Engagement Activity | Participation in an activity, workshop or similar |
| Part Of Official Scheme? | No |
| Geographic Reach | Regional |
| Primary Audience | Postgraduate students |
| Results and Impact | I competed in the Merseyside heat of the Institute of Physics' Three Minute Wonder competition, an event whereby the competitors attempt to convey the central thesis of their research in three minutes. I used augmented reality to achieve this aim and received a significant amount of interest from the attendees afterwards. |
| Year(s) Of Engagement Activity | 2019 |
| Description | Liverpool Science Park - Meet the Tenants |
| Form Of Engagement Activity | A talk or presentation |
| Part Of Official Scheme? | No |
| Geographic Reach | Local |
| Primary Audience | Industry/Business |
| Results and Impact | My talk was delivering to tenants of the Liverpool Science Park, mainly owners and employees of technology and data science companies. I discussed the work done by the High Performance Computing research group at the Astrophysics Research Institute and discussed the field of computational cosmology at large. This resulted in questions related to the physical realism of such simulations and the insights that could be gained. |
