  • The Deepest Chandra View of RBS 797: Evidence for Two Pairs of Equidistant X-ray Cavities 
    Ubertosi, F.; Gitti, M.; Brighenti, F.; Brunetti, G.; McDonald, M.; Nulsen, Paul; McNamara, B.; Randall, Scott; Forman, William; Donahue, M.; Ignesti, A.; Gaspari, M.; Ettori, S.; Feretti, L.; Blanton, E. L.; Jones, C.; Calzadilla, M. (2021)
    We present the first results of a deep Chandra observation of the galaxy cluster RBS 797 whose previous X-ray studies revealed two pronounced X-ray cavities in the east-west (E-W) direction. Follow-up VLA radio observations ...
  • Multiple Shock Fronts in RBS 797: The Chandra Window on Shock Heating in Galaxy Clusters 
    Ubertosi, F.; Gitti, M.; Brighenti, F.; McDonald, M.; Nulsen, P.; Donahue, M.; Brunetti, G.; Randall, Scott; Gaspari, M.; Ettori, S.; Calzadilla, M.; Ignesti, A.; Feretti, L.; Blanton, E. L. (2023)
    Using ~427 ks of Chandra observations, we present a study of shock heating and intracluster medium (ICM) cooling in the galaxy cluster RBS 797. We discover three nested pairs of weak shocks at roughly 50, 80, and 130 kpc ...
  • Redshift Evolution of the Feedback-Cooling Equilibrium in the Core of 48 SPT Galaxy Clusters: A Joint Chandra-SPT-ATCA Analysis 
    Ruppin, F.; McDonald, M.; Hlavacek-Larrondo, J.; Bayliss, M.; Bleem, L. E.; Calzadilla, M.; Edge, A. C.; Filipovic, M. D.; Floyd, B.; Garmire, G.; Khullar, G.; Kim, K. J.; Kraft, R.; Mahler, G.; Norris, R. P.; O'Brien, A.; Reichardt, C. L.; Somboonpanyakul, T.; Stark, Antony A.; Tothill, N. (2023)
    We analyze the cooling and feedback properties of 48 galaxy clusters at redshifts 0.4 <sub>cav</sub> observed at low redshift does not evolve with redshift, we use these measurements in order to estimate the expected AGN ...
