The Flux of Hard Radiation from M87,f hard radiation from the general direction of Virgo; the experiment discussed here, conducted 16 months later, recorded approximately the same flux from a smaller region of sky that tends to isolate M87 as the most likely candidate for the source.

A Rocket Observation of Cosmic X-rays in the Energy Range between 0.15 and 20 keV,g rocket scanned a celestial region in which the galactic latitude .. changed from 30° to −55° across the galactic plane in the Cygnus-Cassiopeia region. The spectrum of Cyg XR-2 thus obtained is represented by a thermal bremsstrahlung of temperature 3.4 keV modified by the interstellar absorption f

Techniques for Improving the Sensitivity of Proportional Counters Used in X-ray Astronomy,n the energy range from 1 to 50 keV, proportional counters have advantages over other types of detectors; they provide energy resolution and they can be made relatively easily with very large window areas.
