After ATLAS spotted the object, Margutti's team quickly obtained follow-up observations of The Cow with NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and INTEGRAL hard X-ray laboratories, soft X-rays at XMM-Newton and radio antennae at the Very Large Array toward The Cow.
This conclusion can be extended to the flare on November 4,2003, if we assume that maximum energy release was determined from data on hard X-rays.
It is the first free-electron laser (undulating magnets are shown) to produce pulses of hard X-rays, light whose wavelength is close to the width of an atom.
Several members of the joint SLAC/Stanford Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) are on the NuSTAR science team and are looking forward to their first view through the hard X-ray window.
The report also noted that "important scientific issues which require UV radiation have decreased in number since the 1984 Seitz-Eastman report compared to those which require hard x-rays."
Only Swift's hard x-rays help scientists directly detect the energetic black hole, also called active galactic nuclei (AGN) - which can block ultraviolet, optical and low-energy, or soft X-ray, light.
Harrison (Caltech); it would be the first X-ray observatory to use focusing optics to image in hard X-rays. David J.
in an unrelated experiment, Carol Jo Crannell of Nasxs Goddard Space Flight Center in Greenbelt, Md., and her colleagues hope to begin imaging flares in the light of hard X-rays and gamma rays using a seven-foot-long balloon-borne telescope that they hope to fly for two weeks this fall.
18, the nova emitted hard X-rays with energies above 10,000 electron volts or several thousand times that of visible light when it reached an intensity equivalent to that of the famous Crab Nebula, a supernova remnant that serves as a calibration target for high-energy observatories and is considered one of the brightest sources beyond the solar system at these energies.
Five of them are known as soft gamma repeaters, or SGRs, because they sporadically release large, short bursts (lasting about 0.1 s) of low energy (soft) gamma rays and hard X-rays.
