RESEARCH SUMMARy

In his work, Krzysztof studies the properties of dark matter, dark energy, and the nature of gravity. His contribution to the development of the field includes works on the formation of structures within exact inhomogeneous models and the investigation of light propagation. Krzysztof is most known for his work on the Szekeres models and his engagement in numerical cosmology and investigation of cosmic voids (cosmic voids are vast regions that are avoided by galaxies). His work on light propagation effects resulted in the development the Doppler magnification method, which can be used to measure the mass of cosmic voids. Krzysztof is a member of the Legacy Survey for Space and Time (LSST) and aims to use the LSST data to map so far uncharted cosmic voids.

    Changing the face of the Universe: Cosmological simulations from first principles in general relativity
    1 Jan 2024 - 31 Dec 2026

    Project Total: $941,000; This project addresses cosmology's biggest mystery with the hypothesis that effects usually attributed to 'dark energy' arise from an incomplete understanding of Einstein's general relativity. Einstein's equations as a relation between matter and geometry are well tested on the scales of stars and black holes. However, on large scales matter forms a vast cosmic web of voids, sheets and filaments containing galaxy clusters. Taking an average of the small geometries to get a geometry for the whole universe is an unsolved problem, which this project aims to provide an answer for.

    Australian Access to the Legacy Survey for Space and Time

    Project Total: $1,608,595; The Legacy Survey for Space and Time (LSST) is a 10-year US survey where the entire Southern Sky will be imaged every few days starting in 2023. The dataset will provide the highest resolution and sensitivity images ever recorded as well as 10 million alerts per day to transient objects, transforming many areas of astrophysics. The 8.4m telescope is under construction in Chile with over 1000 scientists from 25+ countries already involved. This proposal supports in-kind contributions to LSST, providing full membership of LSST to ~50 Australian astronomers and their students. Expected outcomes include training of young researchers in big data, strong international links and enhanced capacity for Australian leadership in astrophysics research. Funded by: Australian Research Council - Grant-Linkage Infrastructure; University of Tasmania ($21,900).
