1. Understanding the large-scale structure of the the21-cm signal originating from the Epoch of Reionisation
Sammanfattning : The first billion years from the beginning of the Universe is the focus of multiple astronomical facilities in the upcoming decade. This unique era is marked by the formation of the first stars and galaxies, which release ionising radiation into the intergalactic medium(IGM). LÄS MER
2. Reconstructing the Primordial Seeds of Cosmic Structures in Galaxy Surveys
Sammanfattning : One of the most outstanding questions in modern cosmology concerns the physical processes governing the primordial universe and the origin of cosmic structure. These primordial signals appear in a variety of cosmic large-scale structure probes, e.g. LÄS MER
3. Effects of the Higgs field on Inflation and Reheating
Sammanfattning : The model of inflation - a period of accelerated expansion in the very early Universe - was introduced to give solutions to a number of problems encountered in the Standard Big Bang paradigm. Additionally, due to its quantum nature, inflation is able to generate the necessary primordial inhomogeneity “seeds”, which eventually evolve into large-scale structures. LÄS MER
4. Modelling and Detecting Kilonovae in the Rubin Observatory Era
Sammanfattning : Survey astronomy is a powerful tool for discoveries in astrophysics and cosmology. In the coming years, this field will be revolutionised with the start of the ten-year Legacy Survey of Space and Time (LSST), to be conducted at the Vera C. Rubin Observatory. LÄS MER
5. Survey Astronomy with the LSST and Multimessenger Synergies
Sammanfattning : Survey astronomy has become a powerful tool for discoveries in astrophysics and cosmology. In the coming years this approach will be taken even further with the start of the ten year survey of the Large Synoptic Survey Telescope. LÄS MER
