Supernovae Seminar

Next Thursday, the astronomer Robert P. Kirschner visits the South Island to talk about supernovae observations, without necessarily committing to the Dark Force.

Supernova samples are now large enough that systematic errors dominate over statistical uncertainties, so better understanding, not just a larger sample, is required to make progress on this question. New observations carried out at near-infrared wavelengths promise to reduce these errors and lead to a more certain knowledge of the nature of dark energy.
