"UChicago scientists detect first X-rays from mystery supernovas", by Louise Lerner, UChicago News
A team of scientists, including scholars from the University of Chicago, appear to have found the first X-rays coming from type Ia supernovas. "Although other type Ia's with circumstellar material were thought to have similarly high densities based on their optical spectra, we have never before detected them with X-rays," said Vikram Dwarkadas, research associate professor in the Department of Astronomy and Astrophysics.
