Supernovae are the explosive death of high-mass stars. At this explosive event, stars eject heavy elements, such as iron, oxygen, silicon. While enormous explosion energy ionised the ejected gas from the stars, gas containing these elements expands after explosion, and slowly cools down over years, and these elements eventually form molecules and sublimate into dust grains. Supernovae and supernova remnants are considered to be one of the important sources of heavy elements and dust grains in the interstellar medium of galaxies.
Although recent intensive studies established that supernovae do form molecules and dust, actual processes to form them are largely unknown. Particularly, it is challenging to form molecules and dust in very fast expanding gas (about 1000 km per second).
This PhD project aims at investigating dynamics of expanding gas, and chemical processes and abundances of atoms, molecules, and dust. The student is expected to analyse the data obtained by JWST (James Web Space Telescope), ALMA (Atacama Large Millimeter Array), VLT (Very Large Telescope), APEX (Atacama Pathfinder Experiment).
The project is about analysing the astronomical observational data. The project involves some basic coding skill, and knowledge of python is advantage.
Eligibility
The typical academic requirement is a minimum of a 2:1 physics and astronomy or a relevant discipline.
Applicants whose first language is not English are normally expected to meet the minimum University requirements (e.g. 6.5 IELTS) (https://www.cardiff.ac.uk/study/international/english-language-requirements)
Applicants should apply to the Doctor of Philosophy in Physics and Astronomy with a start date of 1st October 2022.
Applicants should submit an application for postgraduate study via the Cardiff University webpages (https://www.cardiff.ac.uk/study/postgraduate/research/programmes/programme/physics-and-astronomy) including:
• your academic CV
• a personal statement/covering letter
• two references, at least one of which should be academic
• Your degree certificates and transcripts to date.
In the "Research Proposal" section of your application, please specify the project title and supervisors of this project. You can apply for up to three of our advertised STFC projects by listing them in order of preference in the freetext area of the "Research Proposal" section of the online application form.
In the funding section, please select that you will not be self funding and write that the source of funding will be STFC.
Once the deadline for applications has passed we will review your application and advise your within a few weeks if you have been shortlisted for an interview.
