The universe can be a very sticky place, but just how sticky is a matter of debate.That is because for decades cosmologists have had trouble reconciling the classic notion of viscosity based on the la...
Supernova Remnant Crossing a Density Jump: A Thin-Shell Model
kinematics dynamics
font style='font-size:12px;'>
2014/12/24
The environments of supernova explosions are often inhomogeneous, and there may be jumps in their density structure. We have developed a semianalytic model under the thin-shell approximation for super...
X-ray absorption by the low-redshift intergalactic medium: A numerical study of the Lambda cold dark matter model

2014/12/24
Using a hydrodynamic simulation of a cold dark matter universe with a cosmological constant, we investigate the "X-ray forest" absorption imprinted on the spectra of background quasars by the interven...
XMM-Newton Spectra of Intermediate-Mass Black Hole Candidates: Application of a Monte Carlo Simulated Model

2014/12/24
We present a systematic spectral analysis of six ultraluminous X-ray sources (NGC 1313 X-1 and X-2, IC 342 X-1, Ho IX X-1, NGC 5408 X-1, and NGC 3628 X-1) observed with the XMM-Newton observatory. The...

2014/12/24
We present an analysis of XMM-Newton observations of the superbubble 30 Dor C and compare the results with the predictions from the standard wind-blown bubble model. We find that the observed X-ray sp...
Non-equilibrium ionization model for stellar cluster winds and its application
NGC 3603 general
font style='font-size:12px;'>
2014/12/23
We have developed a self-consistent physical model for superstellar cluster winds based on combining a 1D steady-state adiabatic wind solution and a non-equilibrium ionization calculation. Comparing w...
Accretion, feedback and galaxy bimodality: a comparison of the GalICS semi-analytic model and cosmological SPH simulations

2014/12/22
We believe that a wide range of physical processes conspire to shape the observed galaxy population but we remain unsure of their detailed interactions. The semi-analytic model (SAM) of galaxy formati...
