Using Dark Matter Haloes to Learn about Cosmic Acceleration: A New Proposal for a Universal Mass Function
Dark Matter Haloes Cosmic Acceleration
2011/1/11
Structure formation provides a strong test of any cosmic acceleration model because a successful dark energy model must not inhibit {\black or overpredict} the development of observed large-scale stru...
A Precision Test for an Extra Spatial Dimension Using Black Hole--Pulsar Binaries
Extra Spatial Dimension Black Hole Pulsar Binaries
2011/1/11
We discuss the observable effects of enhanced black-hole mass loss in a black hole--neutron star (BH--NS) binary, due to the presence of a warped extra spatial dimension of curvature radius $L$ in the...
Mass Transfer in Binary Stars using SPH. I. Numerical Method
galaxies active - line formation - radiation mechanism general - scattering - X-rays general
2010/11/12
We present new results from Monte Carlo calculations of the flux and equivalent width
(EW) of the Ni K fluorescent emission line in the toroidal X-ray reprocessor model of

Physical parameters of 62 eclipsing binary stars using the ASAS-3 data$-$I
binaries eclipsing - binaries close - stars fundamental parameters -stars
2010/11/15
We present a detailed light curve analysis of publicly available V band observations of 62 binary stars, mostly contact binaries, obtained by the All Sky Automated Survey (ASAS)-3 project between 2000...
The Determination of the Water Vapor Content in the Pulkovo VKM-100 Multipass Vacuum Cell Using Polymer Sensors of Humidity
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
In spectral studies of water vapor under laboratory conditions (determination of molecular constants, measurement for spectral transmission functions), the amount of water vapor in the time of the mea...
The Laboratory Complex for the Calibration of Photometers Using the Optical Method for Determination of the Water Vapor Content in the Earth Atmosphere
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
We describe the laboratory complex for the calibration of photometers that are used in weather service to measure the water vapor content in the Earth atmosphere.
Foreground removal from WMAP 5yr temperature maps using an MLP neural network
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
One of the main obstacles for extracting the cosmic microwave background (CMB) signal from observations in the mm/sub-mm range is the foreground contamination by emission from Galactic component: main...
Constraining halo occupation properties of X-ray AGNs using clustering of Chandra sources in the Bootes survey region
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
We present the most precise measurement to date of the spatial clustering of X-ray selected AGNs using a sample derived from the Chandra X-ray Observatory survey in the Bootes field. The real-space tw...
Understanding the faint red galaxy population using large-scale clustering measurements from SDSS DR7
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
We use data from the SDSS to investigate the evolution of the large-scale galaxy bias as a function of luminosity for red galaxies. We carefully consider correlation functions of galaxies selected fro...
Strong Constraints to the Putative Planet Candidate around VB 10 using Doppler spectroscopy
astrometry methods statistical stars individual (VB 10) tech-niques radial velocities
2010/3/8
We present new radial velocity measurements of the ultra-cool dwarf VB 10, which was recently announced to host a giant planet detected with astrometry. The new observations were obtained using optica...
Quantum theory, gravity, and the standard model of particle physics : using the hints of today to build the final theory of tomorrow
Quantum theory gravity particle physics
2010/3/19
When a mountaineer is ascending one of the great peaks of the Himalayas she knows that an entirely new vista awaits her at the top, whose ramifications will be known only after she gets there. Her imm...
Comment on "Bayesian evidence: can we beat MultiNest using traditional MCMC methods", by Rutger van Haasteren (arXiv:0911.2150)
data analysis methods statistical
2010/3/18
In arXiv:0911.2150, Rutger van Haasteren seeks to criticize the nested sampling algorithm for Bayesian data analysis in general and its MultiNest implementation in particular. He introduces a new meth...
Noncommutative gauge theory using covariant star product defined between Lie valued differential forms
covariant star product differential forms symplectic manifold
2010/3/18
We develop an internal gauge theory using a covariant star product. The space-time is a symplectic manifold endowed only with torsion but no curvature. It is shown that, in order to assure the restric...
