Job description: We invite applications for a PhD position in cosmology at the University of Geneva, starting in Fall 2021. The successful candidate will join the Cosmology and Astroparticle physics group at the University of Geneva to work under the supervision of Dr. Giulia Cusin.
The candidate must have completed a Master degree in physics or equivalent by the starting date. The position is funded for 4 years. The gross salary ranges from CHF 52'000 to CHF 68'000 per annum. PhD students are required to participate in academic activities such as teaching or the organization of seminars.
Project: There are two types of astrophysical gravitational wave (GW) observables: GW from sources that can be detected individually and the astrophysical background of GW, resulting from the incoherent superposition of signals emitted by all astrophysical sources from the onset of stellar activity until today. These two observables contain complementary astrophysical information and, once combined, they can provide insight on the properties of faint and distant populations that cannot be accessed otherwise. A detailed description of signals from resolvable sources, and of the properties of a stochastic background, including propagation effects, is crucial to extract accurate information on the underlying source population. The goal of the project is two fold. On one side, for resolvable events, we will consider different line of sight effects, analyse how they affect the waveform and study how they can be accounted for when building templates. The second goal is to systematically study the observable properties (e.g. anisotropies and polarisation) of a stochastic background of GW and of its cross-correlation with other electromagnetic observables, and explore how they depend on the underlying astrophysical model of source distribution. The idea is to develop an effective approach to extract/constrain astrophysical information out of future background observations (with third generation GW detectors such as LISA and ET). The project comprises a part of theoretical modeling and as well a numerical/data analysis part.
Group: The Cosmology and Astroparticle physics group is strongly involved in study of CMB physics, relativistic effects in galaxy clustering observation, gravitational wave physics, dark energy, and modified gravity, see http://cosmology.unige.ch/. Senior members of the group are: Camille Bonvin, Julien Carron, Ruth Durrer, Stefano Foffa, Martin Kunz, Lucas Lombriser, Michele Maggiore, Antonio Riotto and Francesco Riva.
We welcome applications from highly qualified applicants seeking to hold external fellowships with us. These can be very competitive and we encourage applicants to submit internal applications to the department first, which will undergo a pre-selection. The internal deadlines vary with the fellowship, please enquire with a faculty member closest to your area of interest for further detail.
An internal application consists of a CV (including details of references), an up-to-date publication list, and a preliminary version of your research proposal.
A partial list of fellowships that can be held in our department follows below. This list is not exhaustive, if there are other national or international fellowships you would like to propose being hosted here, please get in touch.
