  • JWST observations of the Ring Nebula (NGC 6720): I. Imaging of the rings, globules, and arcs

    We present JWST images of the well-known planetary nebula NGC 6720 (the Ring Nebula), covering wavelengths from 1.6 to 25 $\, \mu$m. The bright shell is strongly fragmented with some 20 000 dense globules, bright in H2, with a characteristic diameter of 0.2 arcsec and density nH ~ 105-106 cm-3. The shell contains a narrow ring of polycyclic

  • New insights into the role of AGNs in forming the cluster red sequence

    As a considerable investment of time from various telescope facilities was dedicated toward studying the Spiderweb protocluster at z = 2.2, it so far remains one of the most extensively studied protocluster. We report here the latest results in this field, adding a new dimension to previous research on cluster formation at high redshift. Previous

  • Photometry of the Didymos System across the DART Impact Apparition

    On 2022 September 26, the Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the satellite of binary near-Earth asteroid (65803) Didymos. This demonstrated the efficacy of a kinetic impactor for planetary defense by changing the orbital period of Dimorphos by 33 minutes. Measuring the period change relied heavily on a

  • Spectroscopic identification of rapidly rotating red giant stars in APOKASC-3 and APOGEE DR16

    Rotationally enhanced red giant stars are astrophysically interesting but rare. In this paper, we present a catalogue of 3217 active red giant candidates in the APOGEE DR16 (Apache Point Observatory Galactic Evolution Experiment - Data Release 16) survey. We use a control sample in the well-studied Kepler fields to demonstrate a strong relationship

  • Strong size evolution of disc galaxies since z = 1. Readdressing galaxy growth using a physically motivated size indicator

    Our understanding of how the size of galaxies has evolved over cosmic time is based on the use of the half-light (effective) radius as a size indicator. Although the half-light radius has many advantages for structurally parameterising galaxies, it does not provide a measure of the global extent of the objects, but only an indication of the size of

  • WHaD diagram: Classifying the ionizing source with one single emission line

    Context. The usual approach to classify the ionizing source using optical spectroscopy is based on the use of diagnostic diagrams that compare the relative strength of pairs of collisitional metallic lines (e.g., [O III] and [N II]) to recombination hydrogen lines (e.g., Hβ and Hα). Despite it having been accepted as the standard procedure, it
