My research focuses on the evolution of galaxies and the growth of structure in the Universe. I use two approaches to address questions in these fields. Firstly, I work with multiwavelength datasets to gain new insights into galaxy formation and evolution by
contrasting the views provided by radiation emitted in different wavelengths (in particular those in the mid/far-infrared, and submillimetre). The second approach I use is the detailed study of nearby galaxies where the increased spatial resolution afforded by ground based telescopes and space based observatories enables a better understanding of the physical processes governing galaxy evolution.
I am very interested in dust emission in galaxies near and far. With JWST we can now access the MIR range from 1 to 25 microns (MIRI-MRS+NIRSpec combined). In particular, I am interested in the properties of the smallest particles of the dust distribution, Polycyclic Aromatics Hydrocarbons (PAH). To aid our understanding of PAH emission we have developed PAH grids (described in Rigopoulou+21 and Rigopoulou+24). The grid files are available from this link
