This is a wavelength-dispersive spectrometer that will provide high spectral resolution in the soft X-ray band.
The system is an X-ray nova, meaning that it it experiences periodic outbursts in the X-ray band of the spectrum.
The galaxy cluster is the brightest cluster in the sky when observed in the X-ray band.
An X-ray microscope uses electromagnetic radiation in the soft X-ray band to produce images of very small objects.
Ariel 5 was dedicated to observing the sky in the X-ray band.
Although it has a lower luminosity than component A, star B emits more energy in the X-ray band.
Such minute eyes can see clearly only in ultraviolet and, in good light, the longest wavelengths of the X-ray band.
Both also offer a continuous range of available wavelengths, allowing seamless progress into the X-ray band.
This star is moderately luminous in the X-ray band, with a variable energy emission of 10 erg s in the range 0.2 12 keV.
Ariel 5 was a joint British and American space observatory dedicated to observing the sky in the X-ray band.
