Density contrast of MW BHB stars in the stellar halo at 50 < r_q/kpc < 120 seen in Galactocentric coordinates (ϕ_gc, θ_gc). The Mollweide projection is divided into a grid of 192 pixels (nside = 4) with equal area. We delineate the approximate Galactocentric regions associated with OVO, Pisces, and Northern OverDensity as the cyan, green, and magenta lines, respectively. The present-day position of the LMC and SMC are shown as the purple scatter points. LMC’s past trajectory (see Vasiliev 2023 for details) and Sgr stream are represented by the solid purple and dashed black lines, respectively.
