Statistical anisotropy of CMB as a probe of conformal rolling scenario
Statistical anisotropy CMB probe conformal rolling scenario
2012/2/21
Search for the statistical anisotropy in the CMB data is a powerful tool for constraining models of the early Universe. In this paper we focus on the recently proposed cosmological scenario with confo...
Modelling interaction of relativistic and non-relativistic winds in binary system PSR B1259-63/SS2883 - II. Impact of magnetization and anisotropy of the pulsar wind
HD – shock waves - pulsars: binaries
2011/10/19
In this paper, we present a numerical study of the properties of the flow produced by the collision of a magnetized anisotropic pulsar wind with its environment in binary system. We compare the impact...
An Estimator for statistical anisotropy from the CMB bispectrum
Estimator statistical anisotropy CMB bispectrum
2011/10/13
Various data analyses of the Cosmic Microwave Background (CMB) provide observational hints of statistical isotropy breaking. Some of these features can be studied within the framework of primordial ve...
Statistical Anisotropy and the Vector Curvaton Paradigm
Statistical Anisotropy Vector Curvaton Paradigm
2011/10/17
The vector curvaton paradigm is reviewed. The mechanism allows a massive vector boson field to contribute to or even generate the curvature perturbation in the Universe. Contribution of vector bosons ...
Implications of the Cosmic Ray Electron Spectrum and Anisotropy measured with Fermi-LAT
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/23
The Fermi Large Area Telescope (LAT) collaboration recently released the updated results of the measurement of the cosmic ray electron (CRE) spectrum and published its first constraints on the CRE ani...
The universal distribution of halo interlopers in projected phase space. Bias in galaxy cluster concentration and velocity anisotropy?
Galaxies clusters general Cosmology miscellaneous (Cosmology) dark matter Galaxies halos Gravitational lensing weak Methods numerical
2010/3/9
When clusters of galaxies are viewed in projection, one cannot avoid picking up foreground/background interlopers, that lie within the virial cone (VC), but outside the virial sphere. Structural and k...
A CMB temperature anisotropy experiment for the LMT。
27-day variations of the galactic cosmic ray intensity and anisotropy
cosmic ray intensity 27-day variations
2009/5/27
We study the 27-day variations of the galactic cosmic ray (GCR) intensity and three dimensional (3-D) anisotropy in different polarity periods of the solar magnetic cycle. We found that the larger am...
Average Anisotropy Characteristics of High Energy Cosmic Ray Particles and Geomagnetic Disturbance Index Ap
Cosmic rays anisotropic variation geomagnetic disturbances
2009/5/12
The average characteristics of the diurnal and semi-diurnal
anisotropy of cosmic ray intensity at relativistic energies have been obtained
by using data from the worldwide grid of neutron monitor fo...
Interpretation of the Global Anisotropy in the Radio Polarizations of Cosmologically Distant Sources
Polarization magnetic fields galaxies:active galaxies: high-redshift cosmology:miscellaneous elementary particles
2009/5/7
We present a detailed statistical study of the observed
anisotropy in radio polarizations from distant extragalactic objects. This
anisotropy was earlier found by Birch (1982) and reconfirmed by Jai...
