Fragmentation and Evolution of Molecular Clouds. III: The Effect of Dust and Gas Energetics
Hugo Martel, Andrea Urban, Neal J. Evans
Dust and gas energetics are incorporated into a cluster-scale simulation of star formation in order to study the effect of heating and cooling on the star formation process. We bui…
Do Lognormal Column-Density Distributions in Molecular Clouds Imply Supersonic Turbulence?
K. Tassis, D. A. Christie, A. Urban +4
Recent observations of column densities in molecular clouds find lognormal distributions with power-law high-density tails. These results are often interpreted as indications that…
Fragmentation and Evolution of Molecular Clouds. II: The Effect of Dust Heating
Andrea Urban, Hugo Martel, Neal J. Evans
We investigate the effect of heating by luminosity sources in a simulation of clustered star formation. Our heating method involves a simplified continuum radiative transfer method…
A Parameter Study of the Dust and Gas Temperature in a Field of Young Stars
Andrea Urban, Neal J. Evans, Steven D. Doty
We model the thermal effect of young stars on their surrounding environment in order to understand clustered star formation. We take radiative heating of dust, dust-gas collisional…
A Multivariate Analysis of Galaxies in the Hubble Deep Field North
Michael R. Corbin, Andrea Urban, Elizabeth Stobie +2
We use the ultraviolet and optical WFPC2 and near-infrared NICMOS images of the Hubble Deep Field North to measure and statistically compare an array of parameters for over 250 of…
