TL;DR: In this article, the authors present a theoretical framework in which bound stellar clusters arise naturally at the high-density end of the hierarchy of the interstellar medium (ISM) and due to short free-fall times, these high density regions achieve high local star formation efficiencies, enabling them to form bound clusters.

TL;DR: In this paper, an end-to-end, two-phase model for the origin of globular clusters (GCs) is presented, where populations of stellar clusters form in the high-pressure discs of high-redshift ($z>2$) galaxies (a rapid-disruption phase due to tidal perturbations from the dense interstellar medium), after which the galaxy mergers associated with hierarchical galaxy formation redistribute the surviving, massive clusters into the galaxy haloes, where they remain until the present day.

TL;DR: The star formation rate in the central molecular zone (CMZ) of the Milky Way is lower by a factor of ≥ 10 than expected for the substantial amount of dense gas it contains, which challenges current star formation theories as discussed by the authors.

TL;DR: In this paper, the formation and assembly history of the Milky Way (MW) was reconstructed from the age-metallicity distribution of 96 Galactic globular clusters (GCs) to infer the merger tree of the MW.

TL;DR: In this article, an orbital model for the gas stream observed in the Central Molecular Zone (CMZ) is presented by integrating orbits in the empirically constrained gravitational potential and represents a good fit to the observed position-velocity distribution of dense (n > several 103 cm-3) gas, reproducing all of its key properties.
