Using Computational Essays to Redistribute Epistemic Agency in Undergraduate Science
Tor Ole B. Odden, Devin Silvia, Anders Malthe-Sørenssen
This article reports on a study investigating how computational essays can be used to redistribute epistemic agency--cognitive control and responsibility over one's own learning--t…
The Impact of Enhanced Halo Resolution on the Simulated Circumgalactic Medium
Cameron B. Hummels, Britton D. Smith, Philip F. Hopkins +7
Traditional cosmological hydrodynamics simulations fail to spatially resolve the circumgalatic medium (CGM), the reservoir of tenuous gas surrounding a galaxy and extending to its…
Validating Semi-Analytic Models of High-Redshift Galaxy Formation using Radiation Hydrodynamical Simulations
Benoit Côté, Devin Silvia, Brian W. O'Shea +2
We use a cosmological hydrodynamic simulation calculated with Enzo and the semi-analytic galaxy formation model (SAM) GAMMA to address the chemical evolution of dwarf galaxies in t…
Trident: a universal tool for generating synthetic absorption spectra from astrophysical simulations
Cameron Hummels, Britton Smith, Devin Silvia
Hydrodynamical simulations are increasingly able to accurately model physical systems on stellar, galactic, and cosmological scales, however, the utility of these simulations is of…
JINA-NuGrid Galactic Chemical Evolution Pipeline
Benoit Côté, Christian Ritter, Falk Herwig +5
Galactic chemical evolution is a topic that involves nuclear physics, stellar evolution, galaxy evolution, observation, and cosmology. Continuous communication and feedback between…
The Orion Fingers: Near-IR Adaptive Optics Imaging of an Explosive Protostellar Outflow
John Bally, Adam Ginsburg, Devin Silvia +1
Aims. Adaptive optics images are used to test the hypothesis that the explosive BN/KL outflow from the Orion OMC1 cloud core was powered by the dynamical decay of a non-hierarchica…
Numerical Simulations of Supernova Dust Destruction. II. Metal-Enriched Ejecta Knots
D. W. Silvia, B. D. Smith, J. M. Shull
Following our previous work, we investigate through hydrodynamic simulations the destruction of newly-formed dust grains by sputtering in the reverse shocks of supernova remnants.…
Ejecta Knot Flickering, Mass Ablation, and Fragmentation in Cassiopeia A
Robert A. Fesen, Jordan A. Zastrow, Molly C. Hammell +2
Ejecta knot flickering, ablation tails, and fragmentation are expected signatures associated with the gradual dissolution of high-velocity supernova (SN) ejecta caused by their pas…
Numerical Simulations of Supernova Dust Destruction. I. Cloud-crushing and Post-processed Grain Sputtering
D. W. Silvia, B. D. Smith, J. M. Shull
We investigate through hydrodynamic simulations the destruction of newly-formed dust grains by sputtering in the reverse shocks of supernova remnants. Using an idealized setup of a…
Three Modes of Metal-Enriched Star Formation in the Early Universe
Britton D. Smith, Matthew J. Turk, Steinn Sigurdsson +2
Simulations of the formation of Population III (Pop III) stars suggest that they were much more massive than the Pop II and Pop I stars observed today. This is due to the collapse…
Extending the Model of KH 15D: Estimating the Effects of Forward Scattering and Curvature of the Occulting Ring Edge
D. W. Silvia, E. Agol
The periodic eclipses of the pre-main-sequence binary, KH 15D, have been explained by a circumbinary dust ring inclined to the orbital plane, which causes occultations of the stars…
