On Atomic Line Opacities for Modeling Astrophysical Radiative Transfer
In astrophysics, line opacity is a primary source of uncertainty in theoretical calculations of radiative transfer. Much of this uncertainty is dominated by the inability to resolve the width and separation in frequency of sharp atomic transition lines, leading to the common use of approximate frequency-averaged treatments for the lines. In a previous paper, we calculated shock-cooling emission following explosions in core-collapse supernovae using a mult-group radiative transfer code, and comp…

When you say you need hope about climate change, what do you really need?
Maybe it's proof your actions matter.
Maybe it's permission to want a better future.
Maybe it's feeling less alone.
Your brain treats hope like a prediction. When reality doesn't match, hope breaks.
But agency doesn't break.
Community doesn't break.
Imagination doesn't break.
What if we stopped chasing hope and built something stronger?
