Brief summaries of two recent Nature papers: one on a new class of ultraluminous supernova, the other on the first detection of the supermassive black holes population in the high redshift universe.
The new XENON100 results do not support models of inelastic dark matter used to reconcile the DAMA modulation signal with null detections from other experiments. But what’s DAMA and “inelastic dark matter”?
Previously, it was impossible to find out the inner source behind a red giant’s light – hydrogen fusion in a shell, or helium fusion in the core? Using Kepler, the authors of this paper show how to do this observationally using asteroseismology.
