Objective
Research objectives and content
The goal of this research project is to identify signatures of important events in cosmic history which can be used to test cosmological models. Particular focus will be given to observations of the cosmic microwave background (CMB) anisotropies; these are being investigated by a wide range of ground and balloon-based observational programs at present, and will be the subject of investigation of two upcoming satellite projects. Work shall be carried out on three specific projects. 1. The Sunyaev-Zel'dovich effect: The interaction of the microwave background with hot gas in clusters provides a unique signature which can be used to identify galaxy clusters at high redshift. This is a particularly strong probe of the density of the Universe. 2. Analysis of CMB anisotropies: Ongoing and forthcoming observations of these anisotropies provides the most unambiguous probe of cosmological parameters such as the Hubble parameter and the nature of irregularities in the Universe. We will prepare statistical tools needed to estimate these parameters from large data-sets. 3. The Physical State of the Intergalactic Medium: Evolution of the intergalactic medium (IGM) is important to study the evolution of structures. A hot IGM, if it contains all the baryons, can produce a significant CMB spectrum distortion. Quasar observations will be used to constrain the physical state of the IGM.
Training content (objective, benefit and expected impact)
The principal objective is to broaden the scientific knowledge of the applicant, through participation in a large research group with common interests. The candidate will be exposed to new techniques, especially with regard to large computer simulations, which are already well developed at Sussex. The newly acquired skills will be applicable to a wide range of astrophysical projects, including those based around up-coming ESA satellite projects such as Planck and XMM. We anticipate the development of new statistical tools for large data-sets of microwave background observations, and the presentation of predictions for a wide range of cosmological models.
