Abstract: Globular clusters (GCs) are thought to be ancient relics from the early formative phase of galaxies, although their physical origin remains uncertain 1 , 2 . GCs are most numerous around massive elliptical galaxies, where… read more here.

DOI: 10.1093/mnras/staa2508
Abstract: We have used hydrodynamical simulations to model the formation of the closest giant elliptical galaxy, Centaurus A. We find that a single major merger event with a mass ratio up to 1.5, and which has… read more here.

DOI: 10.1093/mnras/stx2030
Abstract: We present significantly improved measurements of turbulent velocities in the hot gaseous haloes of nearby giant elliptical galaxies. Using deep XMM-Newton Reflection Grating Spectrometer (RGS) observations and a combination of resonance scattering and direct line… read more here.
