Scientists ditch approximations modeling universe Einstein’s full theory General Relativity
2016/7/4
Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of...
Stochastic Acceleration and the Evolution of Spectral Distributions in SSC Sources: A Self Consistent Modeling of Blazars' Flares
Stochastic Acceleration Evolution Spectral Distributions
2011/9/30
The broad-band spectral distributions of non-thermal sources, such as those of several known blazars, are well described by a log-parabolic fit. The second degree term in these fits measures the curva...
Modeling of the subgrid-scale term of the filtered magnetic field transport equation
the subgrid-scale term the filtered magnetic field
2011/1/11
Accurate subgrid-scale turbulence models are needed to perform realistic numerical magnetohydrodynamic (MHD) simulations of the subsurface flows of the Sun. To perform large-eddy simulations (LES) of ...
The Spatial Clustering of ROSAT All-Sky Survey AGNs II. Halo Occupation Distribution Modeling of the Cross Correlation Function
The Spatial Clustering ROSAT All-Sky Survey AGNs II
2011/1/11
This is the second paper of a series that reports on our investigation of the clustering properties of AGNs in the ROSAT All-Sky Survey (RASS) through cross-correlation functions (CCFs) with Sloan Dig...
Coronal Loops: Observations and Modeling of Confined Plasma
Coronal Loops Observations Confined Plasma
2011/1/13
Coronal loops are the building blocks of the X-ray bright solar corona. They owe their brightness to the dense confined plasma, and this review focuses on loops mostly as structures confining plasma. ...
Characterizing and Propagating Modeling Uncertainties in Photometrically-Derived Redshift Distributions
Characterizing Propagating Modeling Uncertainties
2010/11/12
The uncertainty in the redshift distributions of galaxies has a significant potential impact on the cosmological parameter values inferred from multi-band imaging surveys. The accuracy of the photo-me...
Genesis and evolution of dust in galaxies in the early Universe I. Modeling dust evolution in starburst galaxies
galaxies high-redshift – galaxies starburst – galaxies evolution – ISM evolution – quasars general – stars massive
2010/11/16
Aims. The aim is to elucidate the astrophysical conditions required for generating large amounts of dust in massive starburst galaxies at high redshift.
Modeling maximum astrophysical gravitational recoil velocities
maximum astrophysical gravitational recoil velocities
2010/11/16
We measure the recoil velocity as a function of spin for equal-mass, highly-spinning black-hole
binaries, with spins in the orbital plane, equal in magnitude and opposite in direction. We con rm that...
Modeling Gravitational Recoil Using Numerical Relativity
Gravitational Recoil Numerical Relativity
2010/11/16
We review the developments in modeling gravitational recoil from merging black-hole binaries and introduce a new set of 20 simulations to test our previously proposed empirical formula for the recoil....
