Seeing stellar explosions in high definition

Dec 06, 2025 New technology is helping astronomers open new windows into novae, stellar explosions that can act as 'laboratories for extreme physics'. (Nanowerk News) An international team of astronomers, including researchers from the University of Michigan, has captured unprecedented images of two stellar explosions—known as novae—within days of their...

X-ray spikes reveal electron beam size

Dec 06, 2025 Researchers have directly observed, for the first time, transverse intensity fluctuations, called 'spikes', in synchrotron light. (Nanowerk News) While synchrotron radiation is often thought of as “stable”, the electromagnetic field exhibits pronounced randomly fluctuating distributions both temporally and spatially. These fluctuations encode spatial information about the electron...
