An automated method to detect and characterise semi-resolved star clusters

Amy E. Miller, Zachary Slepian, Elizabeth A. Lada +8

We present a novel method for automatically detecting and characterising semi-resolved star clusters: clusters where the observational point-spread function (PSF) is smaller than t…

The GALAH Survey: Stellar parameters and abundances for 800,000 Gaia RVS spectra using GALAH DR4 and The Cannon

Pradosh Barun Das, Daniel B. Zucker, Gayandhi M. De Silva +15

Analysing stellar parameters and abundances from nearly one million Gaia Data Release 3 (DR3) Radial Velocity Spectrometer (RVS) spectra poses challenges due to the limited spectra…

All roads lead to (New) Rome: Byzantine astronomy and geography in a rapidly changing world

Richard de Grijs

During the first few centuries CE, the centre of the known world gradually shifted from Alexandria to Constantinople. Combined with a societal shift from pagan beliefs to Christian…

New quasars behind the Magellanic Clouds. II. Spectroscopic confirmation of 136 near-infrared selected candidates

Valentin D. Ivanov, Maria-Rosa L. Cioni, Michel Dennefeld +6

Quasi-stellar objects (QSOs) are a basis for an absolute reference system for astrometric studies. There is a need for creating such system behind nearby galaxies, to facilitate th…

The Origin of Young Stellar Populations in NGC 1783: Accretion of External Stars

Li Wang, Licai Deng, Xiaoying Pang +4

The presence of young stellar populations in the Large Magellanic Cloud cluster NGC 1783 has caught significant attention, with suggestions ranging from it being a genuine secondar…

The GALAH survey: Elemental abundances in open clusters using joint effective temperature and surface gravity photometric priors

Kevin L. Beeson, Janez Kos, Richard de Grijs +10

The ability to measure precise and accurate stellar effective temperatures () and surface gravities () is essential in determining accurate and precise abund…

The VMC Survey -- L. Type II Cepheids in the Magellanic Clouds

Teresa Sicignano, Vincenzo Ripepi, Marcella Marconi +9

Type II Cepheids (T2C) are less frequently used counterparts of classical Cepheids which provide the primary calibration of the distance ladder for measuring in the local Uni…

Extended Main Sequences in Star Clusters

Chengyuan Li, Antonino P. Milone, Weijia Sun +1

Extended main sequences (eMSs) and extended main-sequence turnoffs (eMSTOs) are fascinating phenomena that are routinely observed in star clusters. These phenomena strongly challen…
