Entropy and mass distribution in galaxy groups
Abstract
We present the results of entropy and mass distribution in about 30 galaxy clusters based on Chandra data Only relaxed systems are chosen for our study excluding those dynamically young systems Entropy profiles with various slopes at the cluster center have been found and we compare the central entropy distribution with the radio luminosity of the cluster cD galaxy We have also derived the cluster mass profiles and examine the dispersion of the central mass profile with the radio activity of the cluster cD galaxy The implication on the evolution of the cluster gas core has been discussed We acknowledge support from NASA grant AR6-7004X
