Abstract: One of the six extended X-ray sources found in the Chandra DeepField North iscentred on HDF130, which has recently been shown to be a massive galaxy atz=1.99 with a compact radio nucleus. The X-ray source has a roughlydouble-lobed structure with each lobe about 41 arcsec long, or 345 kpc at theredshift of HDF130. We have analyzed the 2 Ms X-ray image and spectrum of thesource and find that it is well fit by a power-law continuum of photon index2.65 and has a 2--10 keV luminosity of 5.4x10^{43}ergps (if at z=1.99). Anyfurther extended emission within a radius of 60 arcsec has a luminosity lessthan half this value, which is contrary to what is expected from a cluster ofgalaxies. The source is best explained as an inverse Compton ghost of a giantradio source, which is no longer being powered, and for which Compton losseshave downgraded the energetic electrons, gamma> 10^4, required forhigh-frequency radio emission. The lower energy electrons, gamma~1000, produceX-rays by inverse Compton scattering on the Cosmic Microwave Background.Depending on the magnetic field strength, some low frequency radio emission mayremain. Further inverse Compton ghosts may exist in the Chandra deep fields. Submission historyFrom: A.C. Fabian [view email]Full-text links: Download:Current browse context:
