Process leading to supernova explosions and cosmic radio bursts unearthed at PPPL
Oct 07, 2021 (SPX)
The process, called quantum electrodynamic (QED) cascades, can lead to supernovas - exploding stars - and fast radio bursts that equal in milliseconds the energ...
Researchers reveal a wobbly and flared Milky Way disk based on LAMOST-Gaia data
Oct 04, 2021 (SPX)
The Milky Way is a typical disk galaxy. In the classical view of the Milky Way, the disk is symmetric and flat on the whole, like a pancake. Stars in the disk r...
