Title: THE MAGNETIC FIELD STRENGTH IN THE RADIO HOT SPOT OF 3C 123: SYNCHROTRON SELF-COMPTON EMISSION AND EQUIPARTITION

Observer: HARDCASTLE

Subject Category: Active Galaxies and Quasars

Seq: 700134 ObsId: 00829

ABSTRACT

Observations of synchrotron-self-Compton (SSC) emission from the hot spots of powerful extragalactic radio sources are vital for a measurement of the magnetic field strength in these components; without this the dynamics and energetics of these sources are very poorly constrained. With previous X-ray observatories only one such measurement has been made (in the powerful radio source Cygnus A). We now propose observations of the radio galaxy 3C 123 which will detect SSC emission from the hot spot and enable an accurate measurement of the magnetic field strength. 3C 123 is the most suitable object in the sky, after Cygnus A, for such a study. A by-product of our observations will be data on the X-ray core and environment of 3C123 which will shed new light on its peculiar radio structure.
