NEW POSITIONS AVAILABLE SOON! SEE BELOW.
In the VErTIGO (VElocities TestIng Gravity and cOsmology) project we will conduct a novel research based on the state-of-the-art supercomputer simulations of the Universe to go beyond-GR and search for the nature of mysterious Dark Energy.
VErTIGO introduces a novel approach that consists of the use of low-order statistics of galaxy velocities and clustering for testing GR and searching for beyond-GR signatures on intergalactic scales. This approach has several unique advantages: it is (gravity-) model independent, free of significant galaxy bias and largely unaffected by baryonic physics. The disadvantage is that peculiar velocities can only be measured with sufficient accuracy for a small sample of local galaxies and even then there are potentially significant systematic errors in the calibration of distance indicators and, consequently, in the estimate of the peculiar velocities. But this disadvantage is fully compensated by the fact that MG signature stands out much more prominently in peculiar velocities rather than in the cosmic density field. Therefore the potential gain is tremendous as peculiar velocities can provide a novel MG/GR test that also constitute an independent consistency check for the GR framework.
The second-leg of this project will aim at studying in detail baryonic processes in beyond-LCDM models, which will allow to use high-order moments galaxy clustering as a secondary and complementary cosmological gravity probes.
We are seeking for candidates for master and summer project positions.

PostDoc POSITION in the VErTIGO project:
Description:
Applications are invited for a postdoctoral position in computational cosmology at the Center for Theoretical Physics (CTP) PAS in Warsaw, Poland to work in the research project “VErTIGO - VElocities TestIng Gravity and cOsmology” led by prof. Wojciech Hellwing, funded by the Polish National Science Center (NCN).
The group puts particular emphasis on the development and implementation of dedicated simulation software (N-body and hydro) as well as running and analysing large cosmological computer simulations. The successful applicant can also benefit the group’s close links with DESI, LSST and KiDS consortia.
We seek candidates with a Ph.D. degree (awarded no earlier than in 2013*) in astronomy, physics or computational sciences, with experience in building and analysing mock galaxy catalogues. Past experience in working with spectroscopic and velocity galaxy catalogues will be an added value. The position will be available for initially two years, with a possible extension for the third year, subject to satisfactory performance.
The conditions:
The salary will be higher than the usual Polish post-doc rate, and will amount to 138 300 PLN (~32 200 EUR) per annum (before taxes and social security contribution), which is more than adequate to cover costs of living in Warsaw. There is also a dedicated travel budget of 2000 EUR per year and 3500 EUR for personal computing equipment.
How to apply:
Interested candidates should send a cover letter, a brief research statement (max. 4 pages), CV, and a publication list in a single pdf file to [email protected]. Applicants should also arrange to have three letters of reference separately sent to the same email address. Applications submitted by Nov 20th, 2020 will receive full consideration. The position will remain open until filled. For further information please contact prof. Wojciech Hellwing ([email protected]).
The Center for Theoretical Physics of the Polish Academy of Sciences is an equal opportunity employer. Women and members of under-represented groups are particularly encouraged to apply.
* This date can be extended by any period of an official maternity or paternity leave; for details please contact prof. Hellwing.
