Job description:
Context of the position
The Aix-Marseille Initiative of Excellence is funding, through the DARKUNI project (P.I. Julian Bautista), one postdoctoral position at the Centre de Physique de Particules de Marseille (CPPM) for a duration of two years in the topic of observational cosmology. The overall goal of the DARKUNI project is to learn about the dark sector of the Universe from observations of the large-scale structures with both spectro and photometric surveys. Our team is actively working on the measurement of the growth-rate of structures from a joint analysis of redshift-space distortions and peculiar velocities from type-Ia supernovae. This work is carried out in collaboration with international members of two projects: the Dark Energy Spectroscopic Instrument (DESI) and the Zwicky Transient Facility (ZTF). Outcomes of this project will be key in constraining dark energy models or potential modifications to Einstein’s General Relativity, when combining with other cosmological probes. Naturally our work can be extended to the Vera Rubin LSST samples of supernovae.
Activities
The selected candidate will lead the development of the analysis framework that will derive cosmological constraints from a set of low-redshift galaxies from DESI and type-Ia supernovae from ZTF. Several fronts of research are possible: non-linear models of clustering from perturbation theory or simulation-based ones, characterization of systematic effects on the galaxy and supernova samples, realistic mock catalog production, comparison of methodologies, and constraining cosmological parameters. This work will be carried out as part of the relevant working groups in DESI and ZTF. Travel funding is included for participation at collaboration meetings and conferences.
Qualifications
We welcome applications of highly skilled candidates with experience in cosmology, scientific computing, statistics, and data analysis. Experience with data from spectroscopic surveys and galaxy clustering is highly recommended. We value candidates with good writing and communication skills, willing to work as a team locally and in the context of large scientific collaborations. Candidates should have a PhD degree at the time of the start of the contract.
The host institution
The cosmology group at CPPM is composed of 10 permanent researchers and faculty, 8 PhD students, 4 postdocs and a large team of engineers. Our members are part of DESI, ZTF, Euclid and the DESC collaborations. We produce world-leading research in topics related to cosmology with the large-scale structures (baryon acoustic oscillations, redshift-space distortions, voids, cross-correlations with the cosmic microwave background or gravitational lensing) as well as type-Ia supernovae (calibration, simulations, peculiar velocities).
The CPPM is a Joint Research Unit (UMR 7346) part of the Institut national de physique nucléaire et de physique des particules, under the joint supervision of the French National Centre for Scientific Research (CNRS) and Aix-Marseille University. The research conducted at CPPM is at the crossroads of two infinites; ranging from the study of the elementary components of matter - the infinitely small - to the exploration of the cosmos - the infinitely large. Most of our research is carried out within leading international scientific collaborations and our contributions are recognized worldwide. All the CPPM activities are based on values of ethics, deontology and integrity, with a focus on science and society. CPPM is committed to conducting research within the framework of open science, promoting diversity and inclusion in the workplace, and preserving the environment.
