One of the most fascinating and enigmatic pieces of evidence of Nabataean ingenuity is the so-called Zodiac of Khirbet et-Tannur (Jordan), found in a temple built at the mountain summit close to Djebel Tannur in the first half of the second century CE, possibly when the ancient Nabataean Kingdom was already under Roman rule. However, Nabataean

We present a catalog of stellar properties for a large sample of 6676 evolved stars with Apache Point Observatory Galactic Evolution Experiment spectroscopic parameters and Kepler asteroseismic data analyzed using five independent techniques. Our data include evolutionary state, surface gravity, mean density, mass, radius, age, and the

The early Universe presented a star formation environment that was almost devoid of heavy elements. The lowest metallicity stars thus provide a unique window into the earliest Galactic stages, but are exceedingly rare and difficult to find. Here, we present the discovery of an ultra-metal-poor star, Pristine_221.8781+9.7844, using narrow-band Ca H

In this paper, we present the astrophotometric catalogues of 56 globular clusters and one open cluster. Astrometry and photometry are mainly based on images collected within the `HST Legacy Survey of Galactic Globular Clusters: Shedding UV Light on Their Populations and Formation' (GO-13297, PI: Piotto), and the `ACS Survey of Galactic Globular

Context. The Fornax Deep Survey (FDS), an imaging survey in the u', g', r', and i'-bands, has a supreme resolution and image depth compared to the previous spatially complete Fornax Cluster Catalog (FCC). Our new data allows us to study the galaxies down to r'-band magnitude mr' ≈ 21 mag (Mr' ≈ -10.5 mag), which opens a new parameter regime to

We present results from an ongoing investigation using the Kilo Degree Survey (KiDS) on the VLT Survey Telescope (VST) to provide a census of ultra-compact massive galaxies (UCMGs), defined as galaxies with stellar masses {M_{\star }}> 8 × 10^{10} { M_⊙} and effective radii {R_e} 1.5 kpc. UCMGs, which are expected to have undergone very few merger
