Constraining Stellar Feedback: Ionized Gas Structures In Local Starburst Galaxies
Pure sciences Ionized gas structures Interstellar medium Starburst galaxies Stellar feedback
2014/12/9
Stellar feedback, i.e., the return of mechanical energy from supernova explosions, and massive star and AGN winds to the interstellar medium, is one of the fundamental processes that shape galaxy evol...
Constraining dynamical dark energy with a divergence-free parametrization in the presence of spatial curvature and massive neutrinos
Constraining dynamical dark energy divergence-free parametrization presence spatial curvature massive neutrinos
2012/2/21
In this paper, we report the results of constraining the dynamical dark energy with a divergence-free parameterization, $w(z) = w_{0} + w_{a}(\frac{\ln(2+z)}{1+z}-\ln2)$, in the presence of spatial cu...
The WiggleZ Dark Energy Survey: constraining the evolution of Newton's constant using the growth rate of structure
constraining evolution constant using growth rate structure
2011/10/11
We constrain the evolution of Newton's constant using the growth rate of large-scale structure measured by the WiggleZ Dark Energy Survey in the redshift range $0.1 < z < 0.9$. We use this data in two...

Constraining Galactic Magnetic Field Models Starlight
2011/10/8
This paper provides testable predictions about starlight polarizations to constrain the geometry of the Galactic magnetic field, in particular the nature of the poloidal component. Galactic dynamo sim...
A Suzaku Observation of MCG-2-58-22: Constraining the Geometry of the Circumnuclear Material
Observation MCG-2-58-22 Constraining Geometry clear Material
2011/9/26
We have analyzed a Suzaku long-look of the active galactic nucleus MCG-2-58-22, a type 1.5 Seyfert with very little X-ray absorption in the line of sight and prominent features arising from reflection...
