   Sammanfattning : The rate at which stars have formed throughout the history of theuniverse is not constant, it started out slow, increased until around redshift ∼ 2 when it reversed and became slower again. The reason for this behaviour is still being investigated with various models and simulations usually based upon dark matter halos. LÄS MER

3. 2. Galaxy clusters and cosmic voids in modified gravity scenarios

   L3-uppsats, Uppsala universitet/Teoretisk astrofysik

   Författare :Sveva Castello; [2019]
   Nyckelord :Cosmology; galaxy clusters; cosmic voids; f R gravity;

   Sammanfattning : The so-called 'cosmic web', comprising cosmic voids and galaxy clusters, has been proven to be extremely sensitive to deviations from General Relativity. This could be further investigated by future large-scale surveys, such as with the European Space Agency satellite Euclid. LÄS MER
