Image Details
Caption: Figure 3.
False-color images of simulated resolved dwarfs with MV = −9 at 3.5 Mpc, with increasing ellipticities from left (ϵ = 0) to right (ϵ = 0.5). For each image, the size is 1′ × 1′. In the top and bottom rows, dwarfs are placed in different sky positions in the NGC 253 and Cen A data, respectively. Note that NGC 253 is located at high Galactic latitude (b = −88°), such that the foreground extinction is very low (E(B − V) = 0.02 mag), while Cen A is located at low Galactic latitude with higher extinction (b = 19°, E(B − V) = 0.12 mag). We utilize the Cen A data to assess the effects of MW disk contamination and extinction in detecting dwarf galaxies.
