Dark-energy equation of state: how far can we go from Λ?

Hrvoje Stefancic

The equation of state of dark energy is investigated to determine how much it may deviate from the equation of state of the cosmological constant (CC). Two aspects of the problem a…

LXCDM cosmologies: solving the cosmological coincidence problem?

Javier Grande, Joan Sola, Hrvoje Stefancic

We explore the possibility of having a composite (self-conserved) dark energy (DE) whose dynamics is controlled by the quantum running of the cosmological parameters. We find that…

Comment on Hervik's comment (astro-ph/0504071) on evidence of vorticity and shear of the Universe (astro-ph/0503213)

Davor Palle

Hervik's comments on my criticism of the paper of Jaffe et al are irrelevant or wrong.

Comment on the paper of Jaffe et al (astro-ph/0503213) on evidence of vorticity and shear of the Universe

Davor Palle

We show that recent results in the paper of Jaffe et al on evidence of vorticity and shear of the Universe are incorrect. They fit WMAP data with certain Bianchi model which is kno…

On gravitational lensing by quadrupole potentials

Davor Palle

We study gravitational lensing by quadrupole potentials within the linearized gravity approximation and the integration over the unperturbed photon trajectory. It is well known tha…

Pseudo-Schwarzschild Spherical Accretion as a Classical Black Hole Analogue

Surajit Dasgupta, Neven Bilić, Tapas K. Das

We demonstrate that a spherical accretion onto astrophysical black holes, under the influence of Newtonian or various post-Newtonian pseudo-Schwarzschild gravitational potentials,…
