AGN Feedback and the Development of Dusty Multiphase Gas in X-ray Emitting Elliptical Galaxies
Pasquale Temi, Francesco Ubertosi, Fabrizio Brighenti +9
This paper investigates the physical and kinematic properties of dust-rich regions in a small sample of group-centered elliptical galaxies, emphasizing their connection with the ho…
The Cocoon Shocks of Cygnus A: Pressures and Their Implications for the Jets and Lobes
Bradford Snios, Paul E. J. Nulsen, Michael W. Wise +18
We use 2.0 Msec of Chandra observations to investigate the cocoon shocks of Cygnus A and some implications for its lobes and jet. Measured shock Mach numbers vary in the range 1.18…
The X-ray Ribs Within the Cocoon Shock of Cygnus A
R. T. Duffy, D. M. Worrall, M. Birkinshaw +15
We use new and archival Chandra observations of Cygnus A, totalling 1.9 Ms, to investigate the distribution and temperature structure of gas lying within the projected extent…
ALMA observations of molecular clouds in three group centered elliptical galaxies: NGC 5846, NGC 4636, and NGC 5044
Pasquale Temi, Alexandre Amblard, Myriam Gitti +4
We present new ALMA CO(2--1) observations of two well studied group-centered elliptical galaxies: NGC~4636 and NGC~5846. In addition, we include a revised analysis of Cycle 0 ALMA…
Circumgalactic Oxygen Absorption and Feedback
William G. Mathews, J. Xavier Prochaska
OVI absorption in quasar spectra caused by intervening circumgalactic atmospheres suggests a downturn in the atmospheric column density in sightlines passing beyond about 100 kpc f…
Hot gaseous atmospheres in galaxy groups and clusters are both heated and cooled by X-ray cavities
Fabrizio Brighenti, William G. Mathews, Pasquale Temi
Expanding X-ray cavities observed in hot gas atmospheres of many galaxy groups and clusters generate shock waves and turbulence that are primary heating mechanisms required to avoi…
