Polarization of Dust Emission in Clumpy Molecular Clouds and Cores
T. J. Bethell, A. Chepurnov, A. Lazarian +1
Grain alignment theory has reached the stage where quantitative predictions of the degree of alignment and its variations with optical depth are possible. With the goal of studying…
Estimating Column Density in Molecular Clouds with FIR and Sub-mm Emission Maps
S. Schnee, T. Bethell, A. Goodman
We have used a numerical simulation of a turbulent cloud to synthesize maps of the thermal emission from dust at a variety of far-IR and sub-mm wavelengths. The average column dens…
Dust heating by the interstellar radiation field in models of turbulent molecular clouds
Thomas Bethell, Ellen Zweibel, Fabian Heitsch +1
We have calculated the radiation field, dust grain temperatures, and far infrared emissivity of numerical models of turbulent molecular clouds. When compared to a uniform cloud of…
Linear Gas Dynamics in the Expanding Universe: Why the Jeans Scale does not Matter
Nickolay Y. Gnedin, Emily J. Baker, Thomas J. Bethell +9
We investigate the relationship between the dark matter and baryons in the linear regime. This relation is quantified by the so-called ``filtering scale''. We show that a simple ga…
