Galaxies in the young Universe have hitherto mainly been identified using their expected optical colours, but this leaves open the possibility ...Type of Medium: Electronic ResourceURL: -

In present models, such galaxies appear rather late in the history of the Universe as the culmination of a ...Type of Medium: Electronic ResourceURL: -

Published 1981Staff ViewISSN: 1572-9672Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract During a search for X-ray emission from Supernova 1979c, the parent galaxy M100 (NGC 4321) was repeatedly observed with the IPC and HRI instruments aboard the Einstein X-ray Observatory. The X-ray data reveal two possible sources in the arms of the spiral galaxy, two components in the nuclear bulge and extended X-ray emission from the central part of the galaxy (160x160 square arc seconds centered on the nucleus). We find that the estended X-ray emission cannot be explained in terms of inverse Compton effect on radio, optical or 3 K blackbody photons but rather it is likely to originate from supernova remnants (M100 is indeed a prolific supernova producer) and/or early type stars. As for M100 as a whole, the ratio of X-ray to optical liminosity places it half way between “normal galaxies” e.g. M31 or M33 and peculiar or active galaxies.Type of Medium: Electronic ResourceURL: -

Published 1981Staff ViewISSN: 1572-9672Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract Results are presented from an X-ray survey of ∼50 square degrees of the high galactic latitude sky at sensitivities in the range 7·10−14 – 5·10−12 erg/cm2 sec (0·3–3·5 keV) carried out with the Imaging Proportional Counter (IPC) aboard the Einstein Observatory. The extragalactic sample consists of 48 sources which have been used to determine the number flux relation. The content of the sample is analyzed in terms of types of sources and is found to be significantly different from the content of similar samples selected at higher fluxes.Type of Medium: Electronic ResourceURL:
