Clumping of CDM from the cosmological QCD transition
Dominik J. Schwarz, Christoph Schmid, Peter Widerin
The cosmological QCD transition affects primordial density perturbations. If the QCD transition is first order, the sound speed vanishes during the transition and density perturbat…
Primordial Black Holes from the QCD Transition?
Peter Widerin, Christoph Schmid
Can a violent process like sudden reheating after supercooling at the onset of a first-order QCD transition improve the possibility of primordial black hole formation? Underdensiti…
Amplification of Cosmological Inhomogeneities by the QCD Transition
Christoph Schmid, Dominik J. Schwarz, Peter Widerin
The cosmological QCD transition affects primordial density perturbations. If the QCD transition is first order, the sound speed vanishes during the transition and density perturbat…
Primordial black hole formation caused by the QCD transition ?
Peter Widerin, Christoph Schmid
We consider the evolution of cosmological perturbations at the QCD transition, in particular the sudden reheating from a supercooled universe to the transition temperature. Sudden…
Distortions of the Harrison-Zel'dovich spectrum from the QCD transition
Dominik J. Schwarz, C. Schmid, P. Widerin
We investigate the effect of the cosmological QCD transition on the evolution of primordial density perturbations. If the phase transition is first order, the sound speed vanishes…
Deviations from the Harrison-Zel'dovich spectrum due to the Quark-Gluon to Hadron Transition
Christoph Schmid, Dominik J. Schwarz, Peter Widerin
We investigate the effect of the quark-gluon to hadron transition on the evolution of cosmological perturbations. If the phase transition is first order, the sound speed vanishes d…
