    Research interests

    My work at Cardiff has focussed on infrared observations of nearby galaxies. The collaborations I am a part of have utilised far infrared data from the Herschel Space Observatory to understand galaxy evolution from their dust properties. Nearby galaxies give us the best views we have in the universe and the opportunity to study the small scale physics that determines how structures form on much larger scales. A significant portion of my work has been on the Herschel Reference Survey (HRS) attempting to determine differences in the dust and star formation properties of galaxies based on their morphology, Hubble-type and stellar mass. The primary conclusion of the work was that the presence of a bar has little effect on the global dust properties of the galaxies. An immediate piece of follow-up would be to isolate the circumnuclear regions from the disk of resolved barred galaxies to determine whether star formation may be enhanced in the centre, and quenched in the outer regions by the funnelling of material. One difference that was observed, is that the barred galaxies were generally smaller (low stellar mass) suggesting that by the current epoch massive spirals have created and destroyed their bars - assuming bar creation is a cyclic process. The majority of my time has been spent on the Local Group galaxies Andromeda (M31) and the Triangulum (M33). As part of this I have used data from a variety of instruments in addition to Herschel, including GALEX and Spitzer. I have measured unobscured and embedded star formation rates using ultraviolet and infrared data, in order to calibrate against the total far-infrared luminosity and test the star formation law on 140pc scales. My work shows that the star formation law with molecular gas is approximately linear on small scales in these galaxies but I do find evidence of a sub-linear law in M31. This suggests two immediate follow-up pieces of work. The first is to test beyond doubt that the star formation law is sub-linear in M31, which would suggest star formation becomes less efficient at high gas densities. This would require high fidelity data of dense gas tracers and exploration of star formation indicator calibration on small scales. The second is if the star formation law is linear, as long as we trace the dense molecular gas, the next step is to determine how the more diffuse atomic gas, HI, becomes molecular and where it does so more efficiently. One test would be to determine a dust grain size as the greater the surface area to volume of dust, the more sites are available for molecules to form. I would like to continue work on star formation/evolution and the interstellar medium on large scales and nearby galaxy evolution but would also welcome a move to probing the more distant universe as during my degree my main interest was cosmology, evidenced by my seeking out a cosmology topic for my final year project. I would also like the opportunity to broaden my knowledge of astrophysics while I’m at this early stage in my career.
