I'm Gareth Jones (he/him), a PhD student in the Astronomy and Astrophysics group at the University of Warwick, supervised by Elizabeth Stanway.
I was also an undergraduate at the University of Warwick, having completed a MPhys in Physics (2016 - 2020).
My PhD project is working with Binary Population and Spectral Synthesis (BPASS) models to create physically-motivated, panchromatic spectral energy distributions (SEDs). Currently, BPASS models primarily include only stellar emission models, and therefore can only model populations at optical and ultraviolet wavelengths. My work looks to extend these models into the longer wavelength regime of the spectrum, modelling the emission at infrared and radio wavelengths. This leads to my current ongoing task of creating dust models which dominate the emission at infrared wavelengths, generating grids of expected dust emission models for specific input stellar models from BPASS. From this, we hope to determine whether a connection between stellar and dust components can be made, motivating the need for constantly evolving dust models alongside the evolving population synthesis models.
Other projects completed as part of my undergraduate degree:
- My undergraduate final year project focused on a stellar occultation by Titan with supervisor Tom Marsh, where a pipeline was modified to extract flux counts from frames for a moving Titan merging with light from a background star. This allowed an occultation light curve to be derived, from which atmospheric properties of Titan could be derived.
- A summer project under the URSS scheme at Warwick with supervisor Grant Kennedy, which entailed hunting for exocomets within TESS data by searching for asymmetric transits.
Outreach, Volunteering and Other Interests
During my current year as a PhD student I have taken on the role of Senior Graduate Teaching Assistant for the first year module PX149 Mathematics for Physicists. This involved me marking and grading weekly problem sheets, and preparing for and taking weekly seminars for two classes.
I enjoy participating in outreach and volunteering where possible, including the summer of 2018 where I participated in the Warwick in Africa scheme. This involved volunteering in South Africa for 7 weeks, where I travelled to a secondary school in the province of Limpopo and taught Maths to several classes of up to 100 students. For this, I had to prepare my own lessons and worksheets for each class, including marking the returned worksheets and certain exams they had to sit.
I am part of the student committee for the monthly Equitea seminar series, a forum where topics related to Equality, Diversity and Inclusion (ED&I) in Astronomy, Physics and/or STEM are discussed.
