Mach's Principle: Exact Frame-Dragging by Energy Currents in the Universe
Christoph Schmid
We show that the dragging of axis directions of local inertial frames by a weighted average of the energy currents in the universe (Mach's principle) is exact for all linear pertur…
Mach's principle: Exact frame-dragging via gravitomagnetism in perturbed Friedmann-Robertson-Walker universes with
Christoph Schmid
We show that the dragging of the axis directions of local inertial frames by a weighted average of the energy currents in the universe is exact for all linear perturbations of any…
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…
