Metal Abundances in the Hot ISM of Elliptical Galaxies

2011
X-ray spectroscopy provides a powerful tool to measure various elemental abundances in the hot ISM and the measured abundances in turn can be compared with galaxy chemical evolution models to constrain important astrophysical quantities and to help our understanding of the formation and evolution of elliptical galaxies and their ISM. In this chapter, I

Go beyond radial gradient: azimuthal variations of ISM abundance in 3D

Proceedings of the International Astronomical Union, 2018
AbstractUsing 3D spectroscopy data from the TYPHOON Project (PI: B. Madore), I show convincing observational evidence that the ISM oxygen abundance traced by HII regions presents systematic azimuthal variations in NGC 1365 and NGC 2997. I discuss a possible physical origin and on-going efforts to explore the prevalence and cause of such variations.
