Improved measurements of turbulence in the hot gaseous atmospheres of nearby giant elliptical galaxies

Abstract We present significantly improved measurements of turbulent velocities in the hot gaseous haloes of nearby giant elliptical galaxies. Using deep XMM–NewtonReflection Grating Spectrometer (RGS) observations and a combination of resonance scattering and direct line broadening methods, we obta...
