The Cosmological Consequences of the Preon Structure of Matter
Vladimir Burdyuzha, Grigory Vereshkov, Olga Lalakulich +1
If the preon structure of quarks, leptons and gauge bosons will be proved then in the Universe during a relativistic phase transition the production of nonperturbative preon conden…
Space Positronium Detection by Radio Measurements
V. Burdyuzha, Ph. Durouchoux, V. Kauts
The possibility of positronium detection at radio wavelengths is investigated in detail. For orthopositronium, the fine structure lines of the n = 2 level (1.62 cm, 2.30 cm and 3.4…
The Forming of the Cosmological Constant
Vladimir Burdyuzha, Olga Lalakulich, Yuri Ponomarev +1
The problem of the physical nature and the cosmological constant genesis is discussed. This problem can't be solved in terms of the current quantum field theory which operates with…
Binary Pulsar Tests of General Relativity in the Presence of Low-Frequency Noise
Sergei M. Kopeikin, Vladimir A. Potapov
The influence of the low-frequency timing noise on the precision of measurements of the Keplerian and post-Keplerian orbital parameters in binary pulsars is studied. Fundamental li…
Determination of molecular gas properties using methyl cyanide lines
S. V. Kalenskii, V. G. Promislov, A. V. Alakoz +2
A survey of 27 galactic star-forming regions in the 6_K-5_K, 5_K-4_K, and 8_K-7_K CH3CN lines at 110, 92, and 147 GHz, respectively, is made. Twenty-five sources are detected at 11…
Lambda-inflation and CMB anisotropy
V. N. Lukash, E. V. Mikheeva
We explore a broad class of three-parameter inflationary models, called the -inflation, and its observational predictions: high abundance of cosmic gravitational waves consisten…
The relative figure of merit of optical interferometry as compared to spectroscopy. Example of parameter estimates for the circumstellar envelope of P Cyg
M. S. Burgin, A. Chalabaev
When planning new facilities, one is interested to know whether and by how much the new technique is superior to already existing ones. We describe a general approach permitting to…
Detection of new sources of methanol emission at 107 and 108 GHz with the Mopra telescope
I. E. Valtts, S. P. Ellingsen, V. I. Slysh +3
A southern hemisphere survey of methanol emission sources in two millimeter wave transitions has been carried out using the ATNF Mopra millimetre telescope. Sixteen emission source…
The Diffuse Galactic Gamma-Ray Gradient
D. Breitschwerdt, V. Dogiel, H. J. V"olk
One of the unsolved problems in cosmic ray (CR) physics is the small radial gradient of the gamma-ray intensity compared to the inferred CR source distribution in the Galactic disk…
On generation of metric perturbations during preheating
Pavel Ivanov
We consider the generation of the scalar mode of the metric perturbations during preheating stage in a two field model with the potential $V(ϕ, χ)= {m^{2}ϕ^{2}\over 2}+{g^{2}ϕ^{2}χ…
On the Origin of Polarization near the Lyman Edge in Quasars
A. M. Beloborodov, J. Poutanen
Optical/UV radiation from accretion disks in quasars is likely to be partly scattered by a hot plasma enveloping the disk. We investigate whether the scattering may produce the ste…
Search for Non-Triggered Gamma Ray Bursts in the BATSE Continuous Records: Preliminary Results
B. Stern, Ya. Tikhomirova, M. Stepanov +3
We present preliminary results of an off-line search for non-triggered gamma-ray bursts (GRBs) in the BATSE daily records for about 5.7 years of observations. We found more GRB-lik…
Profile instabilities of the millisecond pulsar PSR J1022+1001
M. Kramer, K. M. Xilouris, F. Camilo +6
We present evidence that the integrated profiles of some millisecond pulsars exhibit severe changes that are inconsistent with the moding phenomenon as known from slowly rotating p…
Hard X-ray emitting black hole fed by accretion of low angular momentum matter
Igor V. Igumenshchev, Andrei F. Illarionov, Marek A. Abramowicz
Observed spectra of Active Galactic Nuclei (AGN) and luminous X-ray binaries in our Galaxy suggest that both hot (~10^9 K) and cold (~10^6 K) plasma components exist close to the c…
Post-Newtonian Theory for Precision Doppler Measurements of Binary Star Orbits
S. M. Kopeikin, L. M. Ozernoy
The determination of velocities of stars from precise Doppler measurements is described here using relativistic theory of astronomical reference frames so as to determine the Keple…
The twisted parsec-scale structure of 0735+178
Jose-Luis Gomez, Alan P. Marscher, Antonio Alberdi +1
We present two epoch polarimetric images of the BL Lac object 0735+178 obtained with the Very Long Baseline Array at 22 and 43 GHz. These images provide the highest resolution obse…
