Deadline:  2024-01-07

Location:  Bielefeld, Germany

I am looking to recruit two postdocs (one 3yrs, one 3yrs+1) for a start in autumn 2024 at Bielefeld University (Germany), where I will be moving in March 2024.

The goal of my ERC-funded project “Probing cosmic large-scale structure beyond the average” is to develop new methods for dynamical and statistical description of the large-scale structure of the Universe in order to extract the maximum cosmological information from galaxy surveys such as Euclid. The two posts each relate to one of the core aspects of the project:

1. The extraction of statistical information beyond average densities that dominate the standard two-point correlations. The focus is on developing 1-point statistics for spectroscopic and photometric galaxy clustering as well as weak lensing, in particular counts-in-cells and weak lensing convergence PDFs and density-split statistics in the context of Euclid. New methods will be developed to translate existing theoretical predictions including systematic effects to real observational data and to analyze data from galaxy surveys (Dark Energy Survey and Euclid), in particular by combining two-point and one-point statistics.

2. The description of the phase-space dynamics of dark matter beyond an effective fluid. The focus is on the further development of a wave-based forward model based on Schroeinger equations. This includes the numerical solution of the Schroeinger-Poisson equation, a perturbative treatment of similar Schroeinger equations with external potentials and their combination. The description of dark matter will be translated to survey observables to enable a map-based data analysis.

The project is carried out in the Cosmology and Astroparticle Physics group (Prof. Dr. Uhlemann) at the Faculty of Physics. My team already includes a postdoc and two PhD students (currently at Newcastle University), has a close collaboration with LMU Munich and CEA Saclay, as well as involvement in the Euclid working teams “Additional Galaxy Clustering Probes” (#swg-gc-wp-additional-probes) and “Higher-Order Weak Lensing Statistics”.

Deadline: 08 December 2023 (expected to be extended to 07 January 2024)
