Supernovae Photospheres as Distance Indicators
By examining their expansion rate over time, Type II supernovae provide a way to measure extragalactic distances.
Constraining fine-structure constant variations using QSOs
From measurements of quasar spectra, we can determine whether or not the fine structure constant is really a constant.
Dark matter and the Solar Interior
Depending on how they scatter with nuclei, dark matter particles might affect the structure and evolution of our Sun.
