On the algorithms of radiative cooling in semi-analytic models
semi-analytic models galaxy
2014/12/22
We study the behaviour of multiple radiative cooling algorithms implemented in six Semi-Analytic Models (SAMs) of galaxy formation, including a new model we propose in this paper. We use versions of t...
A 3D radiative transfer framework: XIII. OpenCL implementation
Radiative transfer – Scattering
2011/10/20
We discuss an implementation of our 3D radiative transfer (3DRT) framework with the OpenCL paradigm for general GPU computing. We implement the kernel for solving the 3DRT problem in Cartesian coordin...
Radiative transfer and molecular data for astrochemistry (Review)
radiative transfer atomic data molecular data
2011/10/10
The estimation of molecular abundances in interstellar clouds from spectroscopic observations requires radiative transfer calculations, which depend on basic molecular input data. This paper reviews r...

2010/11/10
Interstellar dust grains are responsible for modifying the spectral energy distribution
(SED) of galaxies, both absorbing starlight at UV and optical wavelengths and con-verting this energy into ther...
Radiative cooling in numerical astrophysics: the need for adaptive mesh refinement
Computational techniques fluid dynamics Radiative recombination Radiative transfer in astrophysics
2010/11/15
Energy loss through optically thin radiative cooling plays an important part in the evolution of astrophysical gas dynamics and should therefore be considered a necessary element in any numerical simu...

Parameters of Massive Protostellar Clouds Radiative Transfer Modeling
2010/11/16
A one-dimensional method for reconstructing the structure of prestellar and proto-stellar clouds is presented. The method is based on radiative transfer computations and a comparison of theoretical an...

Diffuse radiation'Kompaneets equation radiative transfer X-rays
2010/11/12
Radiative transfer equation in plane parallel geometry and Kompaneets equa-tion is solved simultaneously to obtain theoretical spectrum of 1-125 KeV photon energy range. Diffuse radiation field is cal...
Radiative activity of magnetic white dwarf undergoing Lorentz-force-driven torsional vibrations
magnetic white dwarf non-radial pulsations magneto-dipole emission
2010/11/11
We study radiative activity of magnetic white dwarf undergoing torsional vibrations about axis of its own dipole magnetic moment under the action of Lorentz restoring force. It is shown that pulsating...
Effect of Radiative Levitation on Calculations of Accretion Rates in White Dwarfs
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
Elements heavier than hydrogen or helium that are present in the atmospheres of white dwarfs with effective temperatures lower than 25,000 K, are believed to be the result of accretion. By measuring t...
When people talk about global warming or the greenhouse effect, the main underlying scientific concept that describes the process is radiative forcing. And despite all the recent controversy over leak...

Sun full-disk observations Sun atmosphere Sun magnetic fields
2010/3/9
We investigated the radiative emission of different types of solar features in the spectral range of the Ca II K line.
We analyzed full-disk 2k x 2k observations from the PSPT Precision Solar Photom...
