 POSTDOC POSITION IN THE TRIESTE RESEARCH UNIT

(published Sept. 13th, 2024)

INFN is offering a post-doctoral fellowship for research activities to be carried on within InDark, in the Trieste INFN research unit, on the topic of 

New physics at small/medium scales beyond the standard model of cosmology

The deadline for applications is Nov. 15th, 2024 at noon

The official call can be found here.

Here you can find more details on the possible job topics and on the InDark Trieste research unit in general:

Research group (members): Carlo Baccigalupi, Stefano Borgani, Matteo Costanzi, Nicoletta Krachmalnicoff, Pierluigi Monaco, Alex Saro, Emiliano Sefusatti, Roberto Trotta, Milena Valentini, Matteo Viel

Topics of interest for the position: Theoretical and computational cosmology of the large scale structure (LSS) of the Universe aiming at the prediction and interpretation of data to constrain cosmological models, in and beyond the standard model, and structure formation processes. The methods employed could range from: running and post-processing of hydrodynamic/N-body simulations of the LSS; building of realistic mock catalogs of LSS tracers from large to small scales; testing of new theories; machine learning techniques; models of covariance for combination of different cosmological probes; likelihood development and validation for present and future data sets.

The position will be focussed on testing the cosmological models at different scales and redshifts, with emphasis on probe combination, to search for new fundamental physics like: evidence of neutrino masses, evolving dark energy, dark matter properties, modification of gravity, interactions between dark components of the universe.

Current research lines: Current activities of the InDark-Trieste group are: theoretical cosmology, especially in the context of numerical simulations (N-body/hydro methods); tracers of the large scale structures at small/medium scales including the Intergalactic Medium and Galaxy Clusters; Modeling of galaxy clustering; CMB data analysis and forecasts for Stage4 observations, especially in the context of cross-correlation of different tracers.  

The members of the team are involved with leading roles in several ongoing and future collaborations like Euclid, DES, LSST, Simons Observatory, LiteBird, E-ELT etc.
