Berkeley and elsewhere have performed spectroscopic and photometric study of a peculiar supernova designated SN 2021ukt, ...

It’s easy to forget that stars, just like us, have lifetimes. They’re born, they live, and eventually, they die. And for some stars, their death is dramatic, producing an explosion so powerful it can ...

Type Ia supernovae are bright 'standard candles' for measuring cosmic distances. Standard enough to discover dark energy, they're far from identical. Researchers at the international Nearby Supernova ...

Less than 20 years ago, the world learned that the universe is expanding ever faster, propelled by dark energy. The discovery was made possible by type Ia supernovae; extraordinarily bright and ...

So, instead, supernovae are categorized by observed characteristics such as the light curves of how they brighten and fade ...

Figure 1: Swift/UVOT lightcurves of iPTF14atg. There are several caveats in this simple semi-analytical model. First, the model parameters are degenerate. For example, if we reduce the supernova ...

Astronomers discovered an efficient method for standardizing the intrinsic brightness and thus the distance to the cosmic milestones known as Type Ia supernovae. The discovery underlines the crucial ...
