An X-ray view of Pictor A radio lobes: a spatially resolved study
Abstract
A spatially resolved analysis of the lobes of the radio galaxy Pictor A has been performed for the first time starting from a 50 ksec XMM-Newton observation. Magnetic field, BIC, particle density, particle to magnetic field energy density ratios have been measured. Our study shows that BIC varies through the lobes. On the contrary, a rather uniform distribution of the particles is observed. In both the lobes, the equipartition magnetic field, Beq, is bigger than the Inverse Compton value, BIC, calculated from the radio to X-ray flux ratio.
