  2. 1. Understanding the large-scale structure of the the21-cm signal originating from the Epoch of Reionisation

    Author : Ivelin Georgiev; Garrelt Mellema; Jens Jasche; Aurel Schneider; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reionisation; cosmology; 21-cm; large-scale structure; Astronomy; astronomi;

    Abstract : 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). READ MORE

  4. 2. Reconstructing the Primordial Seeds of Cosmic Structures in Galaxy Surveys

    Author : Adam Johansson Andrews; Jens Jasche; David Marsh; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Abstract : 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. READ MORE

  5. 3. Effects of the Higgs field on Inflation and Reheating

    Author : Aliki Litsa; Katherine Freese; Jens Jasche; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; inflation; reheating; Higgs; non-gaussianity; cosmological perturbations; Theoretical Physics; teoretisk fysik;

    Abstract : 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. READ MORE

  6. 4. Modelling and Detecting Kilonovae in the Rubin Observatory Era

    Author : Christian N. Setzer; Hiranya Peiris; Jens Jasche; Stephen Smartt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cosmology; transient surveys; kilonovae; neutron stars; population modelling; Physics; fysik;

    Abstract : 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. READ MORE

  7. 5. Survey Astronomy with the LSST and Multimessenger Synergies

    Author : Christian Setzer; Hiranya Peiris; Jens Jasche; Evan O'Connor; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; binary neutron stars; gravitational waves; LSST; fysik; Physics;

    Abstract : 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. READ MORE
