2001ApJ...562L.129N Thermal Conduction in Clusters of Galaxies Ramesh Narayan and Mikhail V. Medvedev Received 2001 September 26; accepted 2001 October 25; published 2001 November 15 ABSTRACT We estimate the thermal conductivity of a weakly collisional magnetized plasma with chaotic magnetic field fluctuations. When the fluctuation spectrum extends over two or more decades in wavevector, we find that thermal conduction is very efficient; the conduction coefficient is only a factor of ~5 below the classical Spitzer estimate. We suggest that conduction could play a significant role in cooling flows in clusters of galaxies. Subject headings: conduction - cooling flows - galaxies: clusters: general - magnetic fields
