  Title: INVERSE-COMPTON X-RAYS FROM LOBES OF THE RADIO GALAXY NGC 612                   


Abstract:
 We propose to observe the radio lobes of the galaxy NGC 612 to detect the
 inverse-Compton (IC) X-rays from the lobe. By estimating the flux of IC X-rays and
 comparing with the radio flux of synchrotron radiation, we can determine the
 magnetic field strength in the lobe without any assumptions. Because we can also
 estimate the electron energy density in the lobe from the flux of the IC component
 itself, it will be confirmed whether the energy equipartition between particles and
 fields will hold in the lobe or not. Through this observation, we will also discuss
 on the pressure balance between the lobes and the galactic haloes.
