Measuring Dark Matter in Galaxies: The Mass Fraction Within 5 Effective Radii
William E. Harris, Rhea-Silvia Remus, Gretchen L. H. Harris +1
Large galaxies may contain an "atmosphere" of hot interstellar X-ray gas, and the temperature and radial density profile of this gas can be used to measure the total mass of the ga…
Thermally Unstable Cooling Stimulated by Uplift: The Spoiler Clusters
C. G. Martz, B. R. McNamara, P. E. J. Nulsen +9
We analyzed Chandra X-ray observations of five galaxy clusters whose atmospheric cooling times, entropy parameters, and cooling time to free-fall time ratios within the central gal…
Globular Cluster Systems and X-Ray Atmospheres in Galaxies
Gretchen L. H. Harris, Iurii V. Babyk, William E. Harris +1
We compare the empirical relationships between the mass of a galaxy's globular system M_GCS, the gas mass in the hot X-ray atmosphere M_X within a fiducial radius of 5 r_e, the tot…
Origins of molecular clouds in early-type galaxies
Iu. V. Babyk, B. R. McNamara, P. D. Tamhane +3
We analyze observations of the hot atmospheres of 40 early spiral and elliptical galaxies. Using new temperature, density, cooling time, and mass profiles, we explore rel…
X-ray scaling relations of early-type galaxies
Iu. V. Babyk, B. R. McNamara, P. E. J. Nulsen +5
X-ray luminosity, temperature, gas mass, total mass, and their scaling relations are derived for 94 early-type galaxies using archival X-ray Observatory observations. Con…
A Universal Entropy Profile for the Hot Atmospheres of Galaxies and Clusters within
Iu. V. Babyk, B. R. McNamara, P. E. J. Nulsen +4
We present atmospheric gas entropy profiles for 40 early type galaxies and 110 clusters spanning several decades of halo mass, atmospheric gas mass, radio jet power, and galaxy typ…
