    Abstract : 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. READ MORE

  3. 7. Den gudomliga hästen? Hästen i sydskandinavien under bronsåldern
