Fig. 2

Panel a: density map in L_z − $\sqrt{J_{r}}$ $Mathematical equation: $\[\sqrt{J_{r}}\]$$ space of 124 618 stars that were selected from GALAH DR4. The bin size is 11.7 × 0.2 kpc km s⁻¹. Panel b: the wavelet transform map of 500 Monte-Carlo-generated samples in the L_z − $\sqrt{J_{r}}$ $Mathematical equation: $\[\sqrt{J_{r}}\]$$ space for scale J = 5. Centres of the detected structures are shown with white crosses. The structures are the disk, Splash, GSE, and Thamnos. Panel c: wavelet transform map of 500 Monte Carlo-generated samples in the L_z − $\sqrt{J_{r}}$ $Mathematical equation: $\[\sqrt{J_{r}}\]$$ space for a scale of J = 6. The centres of the detected structures are shown with white crosses. GSE and the disk are the two main building blocks. Panel d: same as panel b, but in a gray scale. The ellipses show areas in the L_z − $\sqrt{J_{r}}$ $Mathematical equation: $\[\sqrt{J_{r}}\]$$ space where we selected stars to further analyze the detected kinematic structures.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
