Abstract We present the largest catalog to date of star clusters and compact associations in nearby galaxies. have performed a V -band-selected census across 38 spiral galaxies PHANGS–Hubble Space Telescope (HST) Treasury Survey, measured integrated, aperture-corrected near-ultraviolet- U-B-V-I photometry. This work has resulted uniform catalogs that contain ∼20,000 associations, which passed human inspection morphological classification, larger sample ∼100,000 classified by neural network...

The vigorous development of urban air mobility (UAM) is reshaping the travel landscape, but it also poses severe challenges to safe and efficient operation dense complex airspace. Potential conflicts between flight plans have become a core bottleneck restricting its development. Traditional plan adjustment management methods often rely on deterministic trajectory predictions, ignoring inherent temporal uncertainties in actual operations, which may lead underestimation potential risks....

Planetary systems in mean motion resonances hold a special place among the planetary population. They allow us to study planet formation great detail as dissipative processes are thought have played an important role their existence. Additionally, masses bright resonant can be independently measured via both radial velocities and transit timing variations. In principle, they also quickly determine inclination of all planets system since, for stable, likely coplanar orbits. To describe full...

We present the largest catalog to-date of star clusters and compact associations in nearby galaxies. have performed a V-band-selected census across 38 spiral galaxies PHANGS-HST Treasury Survey, measured integrated, aperture-corrected NUV-U-B-V-I photometry. This work has resulted uniform catalogs that contain $\sim$20,000 which passed human inspection morphological classification, larger sample $\sim$100,000 classified by neural network models. Here, we report on observed properties these...

Planetary systems in mean motion resonances hold a special place among the planetary population. They allow us to study planet formation great detail as dissipative processes are thought have played an important role their existence. Additionally, masses bright resonant may be independently measured both by radial velocities (RVs) and transit timing variations (TTVs). In principle, they also quickly determine inclination of all planets system, for system stable, likely coplanar orbits. To...
