These groupings include infrared, soft X-ray, and hard X-ray beamlines.
Over the years, improved X-ray observations provided mounting evidence that hard X-rays originated in a hot, tenuous corona above the disk, a structure analogous to the hot corona that surrounds the sun.
Astronomers have long speculated that the black hole's snacking should produce copious hard X-rays, but NuSTAR is the first telescope with sufficient sensitivity to actually detect them," said NuSTAR team member Chuck Hailey of Columbia University in New York City.
The nova peaked in hard X-rays -- energies above 10,000 electron volts, or several thousand times that of visible light -- on Sept.
The nova on Sep 18, produced hard X-rays with energies above 10,000 electron volts or several thousand times that of visible light when it reached an intensity equal to that of the famous Crab Nebula, a supernova remnant that serves as a calibration target for high-energy observatories and is considered as one of the brightest sources beyond the solar system at these energies.
These hard X-rays, electromagnetic waves with energies up to 10,000 times that of visible light, have proved their mettle as powerhouses of diagnostic medical imaging.
