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.
Chaplygin-Kalb-Ramond Quartessence
Neven Bilic, Gary B. Tupper, Raoul D. Viollier
Unified dark matter/energy models (quartessence) based upon the Chaplygin gas D-brane fail owing to the suppression of structure formation by the adiabatic speed of sound. Includin…
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…
Existence of Time Operator for a Singular Harmonic Oscillator
V. Mikuta-Martinis, M. Martinis
The time operator for a quantum singular oscillator of the Calogero-Sutherland type is constructed in terms of the generators of the SU(1,1) group. In the space spanned by the eige…
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…
Space-Time Non-Commutativity near Horizon of a Black Hole
M. Martinis, V. Mikuta-Martinis
We consider dynamics of a quantum scalar field, minimally coupled to classical gravity, in the near-horizon region of a Schwarzschild black-hole. It is described by a static Klein-…
