During the first 500 million years of cosmic history, the first stars and galaxies formed and seeded the cosmos with heavy elements.

We aim to conduct a blind, all-sky search for open clusters using 729 million sources from Gaia DR3 down to magnitude $G\sim20$, creating a homogeneous catalogue of clusters including many new objects.

Our results further demonstrate the capability of the circular velocity curve, especially in light of the recent wave of data, in constraining the Milky Way's dark matter halo.

We identify three eras: a Pre-Disk Era (typically >8 Gyr ago), when stars formed on dispersion-dominated orbits; an Early-Disk Era (~ 8 - 4 Gyr ago), when stars started to form on rotation-dominated orbits but with high velocity dispersion, sigma_form; and a Late-Disk Era (< 4 Gyr ago), when stars formed with low sigma_form.

These winds reduce the gas surface density in the inner regions of the galaxy, suppressing the very compact starburst and maintaining an approximately constant half-mass radius.

Active Galactic Nuclei (AGN) can often be identified in radio images as two lobes, sometimes connected to a core by a radio jet.
