Black hole models contradicted by hands-on tests at Sandia’s Z machine

ALBUQUERQUE, N.M. — A long-standing but unproven assumption about the X-ray spectra of black holes in space has been contradicted by hands-on experiments performed at Sandia National Laboratories’ Z machine. Z, the most energetic laboratory X-ray source on Earth, can duplicate the X-rays surrounding black holes that otherwise can be watched only from a great distance and then theorized […]

‘Iron Sun’ is not a rock band, but a key to how stars transmit energy

ALBUQUERQUE, N.M — Working at temperatures matching the interior of the sun, researchers at Sandia National Laboratories’ Z machine have been able to determine experimentally, for the first time in history, iron’s role in inhibiting energy transmission from the center of the sun to near the edge of its radiative band — the section of […]
