Determination of a magnetization parameter of the parsec-scale AGN jets
Determination magnetization parameter parsec-scale AGN jets
2011/9/27
The observed shift of the core of the relativistic AGN jets as a function of frequency allows us to evaluate the number density of outflowing plasma and, hence, the magnetization parameter. New analys...
Distinguishability of scalar field models of dark energy with time variable equation of state parameter
cosmology dark energy–scalar field cosmic microwave background
2010/11/16
The possibility of distinguishing of scalar field models of dark energy with different Lagrangians and time variable equation of state parameter by available observational data is analyzed. The mul-ti...
Intermediate-mass-ratio-inspirals in the Einstein Telescope. II. Parameter estimation errors
Intermediate-mass-ratio-inspirals Einstein Telescope Parameter estimation errors
2010/11/16
We explore the precision with which the Einstein Telescope (ET) will be able to measure the
parameters of intermediate–mass–ratio inspirals (IMRIs), i.e., the inspirals of stellar mass compact object...
Variation in the frequency separations with activity and impact on stellar parameter determination
Variation frequency separations activity impact
2010/11/15
Frequency separations used to infer global properties of stars through asteroseismology can change depending on the strength and at what epoch of the stellar cycle the p-mode frequencies are measured....
GRB spectral parameter modeling
acceleration of particles shock waves turbulence galaxies: jets radiation mecha-nisms non-thermal magnetic fields
2010/11/9
Fireball model of the gamma-ray bursts (GRBs) predicts generation of numerous internal shocks, which efficiently accelerate charged particles and generate relatively small-scale stochastic magnetic an...
Probing the parameter space of HD 49933: a comparison between global and local methods
comparison global local methods
2010/11/16
We present two independent methods for studying the global stellar parameter space (mass M, age, chemical composition X0, Z0) of HD 49933 with seismic data. Using a local minimization and an MCMC algo...
The SEGUE Stellar Parameter Pipeline. V. Estimation of Alpha-Element Abundance Ratios From Low-Resolution SDSS/SEGUE Stellar Spectra
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/5
We present a method for the determination of [alpha/Fe] ratios from low-resolution (R = 2000) SDSS/SEGUE stellar spectra.
Constraints on the Dark Side of the Universe and Observational Hubble Parameter Data
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
This paper is a review on the observational Hubble parameter data that have gained increasing attention in recent years for their illuminating power on the dark side of the universe --- the dark matte...
Parameter estimation biases due to contributions from the Rees-Sciama effect to the integrated Sachs-Wolfe spectrum
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
The subject of this paper is an investigation of the nonlinear contributions to the spectrum of the integrated Sachs-Wolfe (iSW) effect. We derive the corrections to the iSW-auto spectrum and the iSW-...
