Soft X-ray emission from the high galactic latitude X-ray source MX 2140-60
Abstract
Soft X-rays (0.2–1.0 keV) have been detected from the high galactic latitude source MX 2140-60 in a rocket experiment. The measured flux of ∼10‑10 erg cm‑2 s‑1 combined with OSO-7 measurements in 2–40 keV X-rays, are best fit by a power law photon spectrum with spectral index 2.3 and a neutral hydrogen column densityNH=(3–7) 1020 atoms cm‑2. The observations support the source identification with the cluster of galaxies SC 2146-594, as suggested by Lugger.
