- title: Mesh-refinement for laser-plasma interation simulations with WarpX
textwidth: 7
imagewidth: 5
text: >
Yt was used to render this multi-stage laser-plasma acceleration simulation
with the electromagnetic particle-in-cell code
<a href="https://github.com/ECP-WarpX/WarpX">WarpX</a>, see
<a href="https://www.sciencedirect.com/science/article/pii/S0168900218300524"> Vay et al. 2018</a>.
An ultrashort ultraintense laser pulse (red) propagates through a
low-density plasma and triggers plasma oscillations with strong electric
field (yellow-blue). A beam of electrons (white dots) is trapped in this
wake and accelerated to high energies (GeV). The horizontal lines show
lines of plasma particles. For higher accuracy, a refinement patch is added
around the electron beam (white parallelepiped).

text: >
In <a href="http://adsabs.harvard.edu/abs/2019ApJ...875...81Z">
Zhang et al. 2019</a>,
authours used yt to present the 3D simulation of
a mixed-morphology supernova remnant.
The volumetric rendering of density shows in the top panel,
with a density histogram (black curve)
and the transfer function in the bottom panel.
The SNR shock front is in cyan, and dense clouds are in red.

text: >
In <a href="http://adsabs.harvard.edu/abs/2018ApJ...865...81O">O'Connor
& Couch (2018)</a>, the authors used yt for the visualization of their data.
This figure, a volume rendering of entropy near the gain region of a
core-collapse supernova, shows the multidimensional hydrodynamic instabilities
at work. Both turbulence and the standing accretion shock instability
(the spiral wave wrapping around from the left) aid the neutrino mechanism
in reviving the stalled shock.

In <a href="http://adsabs.harvard.edu/abs/2017MNRAS.468.4107R">Ruggiero
& Lima Neto (2017)</a>, the authors used yt to do all the analysis
and visualization of their data. This figure shows gas density
projections of a Milky Way like galaxy falling into a galaxy cluster
with different entry speeds, for the case where the cluster has
a cool-core (first three rows) or does not have a cool-core (last
three rows).

This movie was completely scripted in <a

library, freely available artistic 3D galaxy models and yt-generated
surfaces of a FLASH simulation. AstroBlend tutorials and examples are
available on <a href="http://www.astroblend.com/">the AstroBlend
website</a>, which is still very much under construction. Paper due out at
some point in the (hopefully) near future.

This movie was created completely with yt by Matthew Turk, John Wise, Sam
Skillman, and Mark SubbaRao that shows a zoom-out of a collapsing
metal-free halo and then transitions to another simulation that follows the
main sequence and supernova of a metal-free star. The simulation shown in
the first half was presented in <a
href="http://adsabs.harvard.edu/abs/2009Sci...325..601T">Turk et al.
(2009)</a> and the latter simulation will be published shortly. This
visualization won the Best Visualization Award at the <a
href="http://www.xsede.org/web/xsede13/">XSEDE 13</a> conference and was
exhibited at the Alder Planetarium.
- title: Radiation Pressure in Early Dwarf Galaxies
textwidth: 7
imagewidth: 5
text: >
This multi-panel figure, created with the eps_writer extension, highlights
the magnitude and direction of the acceleration created by radiation
pressure from massive stars in a dwarf galaxy at redshift 8. This
simulation was presented in <a
href="http://adsabs.harvard.edu/abs/2012MNRAS.427..311W">Wise et al.
(2012)</a> and conducted with <a href="http://enzo-project.org">Enzo</a>.
The bottom panels show the density, temperature, and metallicity of the
same slice. This figure was published in the reference above as Figure 9.

This movie shows the density and temperature structure around a forming
protostar that is surrounded by an accretion disk and driving a bipolar
outflow. The simulation was carried out by S. Offner with the ORION code,
the temperature was computed by T. Robitaille with the <a

the visualization was produced in Python using yt and matplotlib.
