Astrophysics Research at Liverpool John Moores University: Newly Appointed Academic Staff
Lead Research Organisation:
Liverpool John Moores University
Department Name: Astrophysics Research Institute
Abstract
This grant will allow six new academic staff, recently employed in the Astrophysics Research Institute, to carry out their World-leading research as they settle into their new academic environment in Liverpool. The areas of interest of these new staff broadly align with the existing scientific strengths of the ARI, namely: the origin of stars; the chemical composition of galaxies; observational and theoretical studies of the Milky Way; large cosmological hydrodynamical simulations of galaxy clusters; theoretical studies to determine the physical properties of supernovae.
Under the heading of the origin of stars, we will investigate how the initial masses of stars forming in the Galaxy change with environment. Observations of the gas in giant star-forming regions will be used to determine key physical properties on scales close to the size of individual stars.
We will carry out a major spectroscopic survey of nearly 1 million stars in the disc and bulge of the Milky Way. This major legacy survey (APOGEE) and its successor (APOGEE-2), partly supported by the Sloan Foundation, will have major impact on questions such as: the chemical composition of the disc and bulge regions of the galaxy; the origin of globular clusters and whether there is evidence for the very first generation (population III) stars. We will also carry out cosmological hydrodynamic simulations of the Milky Way on supercomputers to provide well-matched and high resolution predictions of the merger history of the galaxy to compare with the observations from the forthcoming Gaia satellite mission, which will provide a 3D map of the Milky Way.
Our extragalactic chemical composition work focuses on a new technique, using Red Supergiant Stars, to measure the element abundances in nearby galaxies. By examining physical relationships, such as the correlation between a galaxy's central mass and metallicity, or the abundance gradients within galaxies, we will make important insights into the processes of galaxy formation and evolution.
On the largest scales we will carry out cosmological simulations of galaxy clusters, including all known feedback mechanisms, in order to provide representative samples of mock clusters. Simulation results will be incorporated into real observations from on-going cluster surveys at different wavelengths (including the XMM-Cluster Survey, in which the ARI is heavily involved) in order to make unbiased estimates of the cosmological parameters and physical conditions in the clusters.
We will investigate the outburst properties of supernovae using data from large on-going transient surveys and explore the relationship between the properties of the SN and its progenitor, as well as searching for new types of transients. In particular we will examine a large population of type SN Ia supernovae and study "extreme" events which violate normal behaviour in order to improve their use as cosmological distance indicators.
All of our research uses the most advanced ground-based telescopes, satellites and data analysis techniques to carry out observations, including telescope time on newly commissioned facilities such as ALMA and the KMOS multi-object spectrograph on the VLT, along with space missions such as Gaia. The new staff lead programmes at the international level, which are also technically demanding and feed into the design and operation of the next generation of telescopes and their instruments, such as the E-ELT (EAGLE/EVE), Liverpool Telescope and WHT (WEAVE).

Planned Impact
The major form of impact arising from additional funds to our current Consolidated Grant, will come from existing activities described in more detail in the Pathways to Impact document. These will benefit schools, amateur astronomers and the general public.
At a University level, the Research Support Office have recently launched the LJMU Research Café - a series of informal, cross-cutting research seminars which will be held monthly in one of the University's Learning Resource Centres. At each event four researchers will present their research to a mixed audience from across the University in a series of short presentations. Sessions will not be themed as the intention is to support a varied programme enabling the audience to engage with the rich variety of research which takes place across the University and for presenters to disseminate their research to a broader audience.
In addition, through activities initiated within the ARI, there will be other more traditional forms of public engagement growing from our research. In particular we would anticipate a number of talks, panel discussions and question-and-answer sessions relating to our research. These will vary with respect to audience: schools (from primary upwards), amateur astronomy societies, lecture societies, WI etc. We will also showcase the new research at events organised by the ARI (such as the annual Merseyside Astronomy Day) and, where appropriate, at the Spaceport visitor centre.
In all cases the benefits will be twofold. Obviously, an exposure to current research can stimulate inquiry and interest in any audience. However, a less obvious, but perhaps more important benefit is to use that stimulation to promote an appreciation of science as a whole. This is particularly important for engagement with schools where astronomy has a vital role to play in promoting science and other STEM subjects as potential careers.
In order to facilitate this, younger and less experienced researchers (especially PDRAs and PhD students) are encouraged to present their research to a variety of audiences, with training and support provided by the experienced Outreach team within the ARI.
We will also work with non-science organisations to find ways in which the research can be used to enhance their own work. This sort of impact is difficult to predict in advance, as it is usually opportunistic, but past examples in the ARI have involved work with arts organisations and artists (including musicians, theatre companies, street theatre performers, sculptors, photographers and writers) and organisations that promote access to education (such as Aim Higher).

Description | Discoveries about evolution of stars, galaxies and clusters of galaxies, dark matter and dark energy. Total publication output due to new staff and associated new collaborations rose from 100 p.a. to 200 p.a. - doubling our research productivity. Over the same period research income grew from £5m to over £11m. |
Exploitation Route | Further research into unsolved problems in astrophysics. This award led to successful integration of newly appointed staff into the Consolidated submissions in 2015 and 2018. One newly appointed staff Co-I (Steve Longmore) started the Astro-ecology group at ARI. The ARI's AE project combining infrared astronomical instrumentation expertise with drone technology is impacting the way conservation agencies around the world (e.g. WWF) conduct animal surveys. The thermal-drone enables safe, routine, efficient and cost-effective monitoring and management of animal populations over large and inhospitable areas, with a factor of up to 200x increase in survey efficiency over existing methods. This provides conservation agencies greatly improved data needed to quantify and mitigate biodiversity loss. The thermal drone system is being used routinely to help local fire-fighting teams to find/extinguish annual peat fires in Indonesia which are a major contributor to anthropogenic CO2 emissions. The orders of magnitude improvement in fire extinction efficiency the system offers over existing methods will hopefully lead to substantial reduction in CO2 emissions -- a leading cause of climate change. the amount of income generated for this project has now (Feb 2020) exceeded £1.5m. |

Description | Many outreach activities across all sectors, e.g. Schools, public, policy makers, flower shows. Across discipline funding for astro-ecology using 10 micron cameras on drones flown over conservation areas (Nepal, Africa, Australia) to help preservation of endangered species. Findings are disseminated in astronomical literature and through public events and schools through the National Schools' Observatory. Partly as a result of this grant NSO now has 3,000 registered schools and delivered 140,000 observations to classrooms. We carry out a range of outreach activities visiting schools, astronomical societies and social groups. We also carry out special exhibitions and events at national venues including Tate Liverpool; FACT; the Science Museum London; the London Design Biennale at Somerset House. These have showcased ARI and LJMU research to a total estimated audience in excess of 50,000. Two of our Outreach staff have fEC awards to carry out impact for two funded projects on our renewed Consolidated Grant 2018-21. Under the directorship of Professor Steve Longmore, ARI has developed a major new research area connected to environmental impact, "Astro-ecology". Longmore and team are working with conservation agencies worldwide (e.g. WWF; Endangered Wildlife Trust; Wetland Wildlife trust; National Geographic; Borneo Nature Foundation; Indonesia National Parks; Chester Zoo; Knowsley Safari Park; Morecambe Bay Search and Rescue; several universities), flying infrared instrumentation developed for astronomical purposes on drones. Applications include: animal conservation in rain forests; peat fire detection in Indonesia and human rescue at sea. Starting with an internal LJMU startup award of £25k in 2016, this work has attracted more than £1.5m of external funding (as of Feb 2020) principally through STFC/GCRF grant awards. |
