Contour lines of the 6.1 mm CS J = 1 → 0 line emission in the velocity ranges (10−30) km s-1 (top) and (40−50) km s-1 (bottom), superimposed on a grayscale equivalent-width image of the 6.4 keV low-ionization Fe Kα line emission, in a 17′ × 17′ field of view centered on Sgr A∗. The CS data are from Tsuboi et al. (1999) and the 6.4 keV data from Park et al. (2004). Figure credit: Sangwook Park.
