    PROBING THE OUTSKIRTS OF THE EARLY-STAGE GALAXY CLUSTER MERGER A1750 by Bulbul, Esra, Randall, Scott W., Bayliss, Matthew, Miller, Eric, Andrade-Santos, Felipe, Johnson, Ryan, Blanton, Elizabeth L., Forman, William R., Jones, Christine, Paterno-Mahler, Rachel, Murray, Stephen S., Sarazin, Craig L., Smith, Randall K., Ezer, Cemile, Miller, Eric D, Bautz, Marshall W.

    Published 2018
    “…Finally, we find evidence for diffuse, cool ( < 1 keV) gas at large cluster radii (R 200 ) along the filament, which is consistent with the expected properties of the denser, hotter phase of the warm-hot intergalactic medium. Key words: galaxies: clusters: individual (A1750); large-scale structure of universe; X-rays: galaxies: clusters…”

    THE STATE OF THE WARM AND COLD GAS IN THE EXTREME STARBURST AT THE CORE OF THE PHOENIX GALAXY CLUSTER (SPT-CLJ2344-4243) by McDonald, Michael A., Swinbank, Mark, Edge, Alastair C., Wilner, David J., Veilleux, Sylvain, Benson, Bradford A., Hogan, Michael T., Marrone, Daniel P., McNamara, Brian R., Wei, Lisa H., Bayliss, Matthew B., Bautz, Marshall W.

    Published 2015
    “…We propose that phases of rapid star formation may be common in the cores of galaxy clusters, but so short-lived that their signatures are quickly erased and appear only in a subsample of the most strongly cooling clusters.…”
