Left panel: the distribution of the young giant sample in the XY-plane. Each black point corresponds to a star. The Sun’s position is shown by the ⊙ symbol. The Galactic center is to the right, at (X, Y) =:(R_⊙, 0 kpc), with R_⊙ = 8.277 kpc (GRAVITY Collaboration et al. 2022). Galactic rotation is clockwise. Right panel: same as the left panel, but now showing the regions of positive (>0) overdensities in the Galactic disk based on the young giant sample (see the details in the text).
