The observational legacy of preon stars - probing new physics beyond the LHC
F. Sandin, J. Hansson
We discuss possible ways to observationally detect the superdense cosmic objects composed of hypothetical sub-constituent fermions beneath the quark/lepton level, recently proposed…
Preon stars: a new class of cosmic compact objects
J. Hansson, F. Sandin
In the context of the standard model of particle physics, there is a definite upper limit to the density of stable compact stars. However, if a more fundamental level of elementary…
Luminosities of High-Redshift Objects in an Accelerating Universe
Daniel Enstrom, Sverker Fredriksson, Johan Hansson
The results from the Supernova Cosmology Project indicate a relation between cosmic distance and redshift that corresponds to an accelerating Universe, and, as a consequence, the p…
Is Dark Matter made up of Massive Quark Objects?
S. Fredriksson, D. Enstrom, J. Hansson +2
We suggest that dark matter is made up of massive quark objects that have survived from the Big Bang, representing the ground state of ``baryonic'' matter. Hence, there was no over…
