X-ray Sources in Cluster of Galaxies
Abstract
Dr. R. Havlen (ESO statt astronomer in Chile) and Dr. H. Quintana (former ESO fellow in Geneva, now with NRAO, Charlottesville, Virginia, USA) recently undertook a thorough study of the southern X-ray cluster of galaxies CA 0340- 538. Ever since satellites with sensitive X-ray detectors first showed the presence of strong X-ray sources near the centres of rich clusters of galaxies, astronomers have been asking: why and how? Some even think that high-energy astrophysics has never had as fascinating a subject for study as the central regions of X-ray clusters. Here, as in any other field of astronomy, observations are ofparamount importance. Drs. Havlen and Quintana introduce the new field and explain their programme:
