Investigating the early dust-obscured phase of galaxy formation and evolution with the Herschel extragalactic legacy project (astronomy)
Understanding the formation and evolution of galaxies is one of the key objectives in modern cosmology. Observations carried out at far-infrared to submillimeter wavelengths are of paramount importance in this respect. In fact, most of the star forming activity in the Universe occured during a dustoscured phase, in which the UV/optical light from newly born stars was absorbed by dust and re-emitted at far infrared to sub-millimeter wavelengths. Recently, the Herschel Space Observatory has explored the Universe at those wavelengths with unprecedented sensitivity and resolution, providing catalogues of hundreds of thousands of dust-osbcured galaxies. Cardiff
University have had a leading role in the Herschel project and is currently one of the european nodes of the Herschel extragalactic legacy project (HELP) which aims at creating a complete and uniform multiwavelength database for the galaxies detected with Herschel.
The student will be involved in the science exploitation of the HELP mutiwavelength data. He/she will measure fundamental statistics like number counts, luminosity functions and spatial/angular correlation functions of dusty galaxies and will interpret these obsevables using a physical model for the formation and evolution of elliptical galaxies. The project will be carried out in collaboration with the University of Padova (Italy), the International School for Advanced Studies (ISAS/SISSA) in Trieste (Italy) and the University of Oviedo (Spain), thus giving the student opportunities for travelling and for interacting with people outside UK.
This project is available to students applying for funded PhD studentships and may be altered or withdrawn.
Studentships will be awarded to successful applicants from all applications received. Applicants must satisfy RCUK residency rules for the full studentship.
