Cosmological energy in a thermo-horizon and the first law
Cécile Barbachoux, Jérome Gariel, Gérard Le Denmat
We consider a cosmological horizon, named thermo-horizon, to which are associated a temperature and an entropy of Bekenstein-Hawking and which obeys the first law for an energy flo…
Cosmological evolution with a logarithmic correction in the dark energy entropy
Cécile Barbachoux, Jérome Gariel, Gérard Le Denmat
In a thermodynamical model of cosmological FLRW event horizons for the dark energy (DE), we consider a logarithmic corrective term in the entropy to which corresponds a new term in…
Static cylindrical symmetry and conformal flatness
L. Herrera, G. Le Denmat, G. Marcilhacy +1
We present the whole set of equations with regularity and matching conditions required for the description of physically meaningful static cylindrically symmmetric distributions of…
Shear-free radiating collapse and conformal flatness
L. Herrera, G. Le Denmat, N. O. Santos +1
Here we study some general properties of spherical shear-free collapse. Its general solution when imposing conformal flatness is reobtained [1,2] and matched to the outgoing Vaidya…
On the time evolution of the redshift and the luminosity distance
C. Barbachoux, G. Le Denmat
We investigate the temporal evolution of the redshift and the luminosity distance within the standard Friedmann-Roberston-Walker cosmological model. The redshift and luminosity dis…
Generalised equilibrium of cosmological fluids in second-order thermodynamics
Winfried Zimdahl, J'er^ome Gariel, G'erard Le Denmat
Combining the second-order entropy flow vector of the causal Israel-Stewart theory with the conformal Killing-vector property of , where is the four-velocity of th…
