Towards an understanding of astronomical silicate dust based on mineralogy, meteoritics and infrared spectroscopy

Abstract
Tiny dust grains exist throughout the Universe: from the most distant galaxies, to our own Solar System. These grains cause galaxies to shine at infrared wavelengths. Much of the space dust is made of silicates, with a similar composition to rocks, soil and sand on the Earth and to meteorites which are rocks which fall to Earth from space. Mineralogists and meteoriticists study silicate rocks and meteoritic silicates in great detail, but this knowledge is not often used to interpret astronomical data. I am an astrophysicist who tries to understand dusty regions of space, galaxies, exploding stars, newly-forming stars and comets by comparing data from telescopes with laboratory data; I apply the results to computational models to interpret the physics. Where there is insufficient laboratory data, I work with mineralogists, meteoriticists, chemists and physicists to obtain new data. This project will underpin the interpretation of infrared spectra obtained with the James Webb Space Telescope, and older under-interpreted Spitzer and ISO-telescope data. It will also provide an archive of laboratory data for physical models of the passage of light through dusty space and help other astrophysicists to know the composition and physics of astronomical silicate dust.

| Description | The discovery of carbonate (chalk) dust in galaxies, star-formation regions and in the surroundings of ancient stars as part of a collaboration between an Earth Scientist and an astrophysicist. It explains the existence of a distinctive absorption band in light which has passed through these regions. Carbonates are an important component of rocks on Earth. The work improves our understanding of the chemistry of interstellar environments. |
| Exploitation Route | The data will be used to analyse spectra from JWST and PRIMA and also by Earth Scientists, Materials' Scientists and Chemists to name a few. |

| Description | Part of the impact of the award was to see if a researcher to return to employment after an long career break (~12 years) at home with children. I have been unemployed since Cardiff University paid for a six month extension of the grant until the end of March 2022. I did not underperform and there are ongoing projects for which I am unpaid e.g. a new collaboration started during the grant has been awarded time on the Webb Space Telescope. The system is hostile to those who take career breaks. The two year duration of the grant during the pandemic and in the current political and economic climate wasn't long enough to re-establish myself. I am now too experienced for PDRA positions and too junior to be considered for lectureships. I have had no success applying for scientific or other jobs within or without the academic community either. This the outcome I predicted in correspondence with STFC before the grant commenced. |

| Results and Impact | Originally planned for 2020, but the National Astronomy Meeting was postponed to 2021 and became an online meeting. I don't know how many people attended. This was a cross-disciplinary session which aimed to enhance the visibility of astronomical dust as a research topic within the astronomical community and to encourage engagement with the planetary science community in time for the launch of JWST. Speakers were from meteoritics and observational and theoretical astrophysics. The abstract was: Dust is ubiquitous in galaxies; it is formed during the creation of supernovae and in the winds of evolved stars; it survives and grows in the diffuse interstellar medium and congregates in molecular clouds before coagulating to form comets, meteorites and planets in young stellar objects. Carbonaceous materials, silicate dust and ices are responsible for extinction, polarization, hidden matter and lots and lots of physical and chemical processes between stars, within and between galaxies. But what is the dust? What are the observational uncertainties? How are observed discrepancies in radio, submm and infrared to X-ray observations to be interpreted? Can meteoriticists, mineralogists and chemists help? There has never been a better opportunity to understand its properties given the forthcoming launch of JWST for mid-infrared observations, JCMT, ALMA, and Herschel results. NAM 2021 will be an excellent opportunity for the discussion of JWST and the development collaborations between theorists,observers, meteoriticists and chemists. I found it very useful to receive abstracts from the community because it helped me update my knowledge after a 13.5 year career break- research groups have come and gone in my absence. The virtual nature of the meeting meant that speakers from Taiwan and Belgium submitted abstracts and gave talks. I also enjoyed the scientific discussion around the topic - I have to learn a lot quickly, so asked a lot of questions. Had a giggle over nomenclature in the different subject areas. I don't think it did my 'career' prospects any harm. |

| Results and Impact | NASAs 2020 Decadal survey report, "Pathways to Discovery in Astronomy and Astrophysics for the 2020s", has recommended a new line of space-based observatories classified as probe missions for the coming decade. The report also identified a far-IR or X-ray probe as highest priority to accomplishing the scientific goals. The goal of this community workshop was to discuss and refine the science that could be accomplished with PRIMA (PRobe far-Infrared Mission for Astrophysics) within the cost and schedule envelopes outlined by the survey. Following my submission of three draft science cases, I was invited to give a lightning talk for the Dust and Metals working group (there were only three.) and to be a discussion panel member. Outcomes so far are the inclusion of my science case in the proposal, and an invitation to give a 10 minute talk, and panel membership at a workshop in March 2023. I suspect that if I was employed, I would already be a formal member of the consortium. |

| Results and Impact | A talk about returning to astronomical research after an extended career break to raise a family. Afterwards - mature members of the audience focussed on the consequences of the extended career break, one audience member congratulated me for showing how older people could contribute to science! A group of younger members came to me afterwards. They were glad that I'd given details about the years of health issues when I was a student because they were having medical challenges and it gave them hope for a good life later on. Feb 2023 update: a British PDRA, in Japan is presenting my slides to an equalities group at JAXA. "What can a returner do?" Abstract: After 7 years as a PDRA I spent 2006 to 2018 out of the workforce as a stay-at-home mother to 2, and then 3 children. I had never intended to take a career break but this can happen when parents are both physicists at the bottleneck between PDRA positions and Lectureships or Fellowships. The children were fun. I also have a life-long invisible disability which negatively affected my formal qualifications, but not my research career. In 2018 I applied for a Returner Fellowship from STFC. I was awarded a 24 month full-time 'pilot' returner Fellowship which began in October 2019. Cardiff University extended my contract for another 6 months to 31st March 2022. I have received no retraining or supervision (I said I didn't need any). Since my return I have: Published 3 first author papers in MNRAS and submitted a fourth (two are single author, none have more than three). Convened a session at NAM 2020. Contributed talks to several online conferences and given an invited talk at another. I wrote a single-author case for the 2021 Roadmap for Astronomy. The future: My minority cross-disciplinary research area should blossom with MIRI/JWST. STFC has extended my grant so I can use unspent travel and experiment money until October. I am now providing (unpaid) scientific into a proposal for PRIMA (a FIR observatory for the 2030s). I am actively excluded from most Research Fellowships, and Academic posts are out of reach even though I remember that "returners and minorities are encouraged to apply". Industry rarely responds to my job applications. So, what can a returner do? I shall talk about successes, surprises and pitfalls. |
