Summary of Research: |
Study of complex carbon molecules in the interstellar/circumstellar medium with the aim to establish their contribution to prebiotic chemistry and to several intriguing astrophysical phenomena (interstellar extinction features and anomalous microwave emission).. I have carried out research on the physical and chemical properties of fullerenes and studied their role on the extinction of radiation in the interstellar medium, the origin of diffuse interstellar bands, the origin of the recently discovered anomalous microwave emission in our Galaxy and on the formation of organic material, particularly prebiotic molecules, in molecular clouds. I work on the search and identification of polycyclic aromatic hydrocarbons (PAHs) and other forms of hydrogenated carbon molecules (fulleranes) in interstellar space, to investigate the role of these molecules on the formation of amino acids and other prebiotic molecules and to establish their contribution to astrophysical phenomena. I am member of the Euclid consortium with a goal to use the mission spectroscopic data to study the early evolution of carbon-based molecules in the Universe.
In this line I have focused my study on Bright Submillimetre Galaxies at high redshift. The main objective is to trace the evolution over time of complex carbon molecules either by measuring PAHs emission as a function of redshift or measurement of 217.5 nm UV bump with redshift. I am studing also the anomalous microwave emission in these galaxies using data from the VLA.
