Aims. The aim is to elucidate the astrophysical conditions required for generating large amounts of dust in massive starburst galaxies at high redshift.
3D numerical MHD modeling of sunspots with radiation transport
MHD – radiative transfer – Sun sunspots – Sun photosphere – Sun magnetic
2010/11/10
Sunspot fine structure has been modeled in the past by a combination of idealized magneto-convection simulations and simplified models that prescribe the magnetic field and flow structure to a large d...
Modeling the Multi-Wavelength Emission of Shell-Type Supernova Remnant RX J1713.7-3946
Modeling the Multi-Wavelength Emission Shell-Type Supernova Remnant
2010/11/9
Emission mechanisms of the shell-type supernova remnant (SNR) RX J1713.7-3946 are studied with multi-wavelength observational data from radio, X-ray,GeV γ-ray to TeV γ-ray band. A Markov Chain Monte C...
Modeling CO Emission: I. CO as a Column Density Tracer and the X-Factor in Molecular Clouds
Modeling CO Emission X-Factor Molecular Clouds
2010/11/12
Theoretical and observational investigations have indicated that the abundance of car-bon monoxide (CO) is very sensitive to intrinsic properties of the gaseous medium,
such as density, metallicity, ...
Determining the Parameters of Massive Protostellar Clouds via Radiative Transfer Modeling
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...
Modeling TeV gamma-rays from LS 5039: An active OB star at the extreme
High Energy Astrophysical Phenomena (astro-ph.HE) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Perhaps the most extreme examples of "Active OB stars" are the subset of high-mass X-ray binaries -- consisting of an OB star plus compact companion -- that have recently been observed by Fermi and gr...
