Linking simulations and observations of star-forming regions I. Masses and temperatures of ALMAGAL-like cores

Birka Zimmermann, Álvaro Sánchez-Monge, Stefanie Walch +1

Dense cores and clumps in massive star-forming regions are studied through (sub-)millimetre continuum observations, but inferred masses and temperatures can be biased by limited re…

Euclid Quick Data Release (Q1) Euclid spectroscopy of quasars. 2. Physical properties from spectral fitting

Euclid Collaboration, J. Calhau, G. Calderone +312

A substantial volume of spectroscopic data has become available with the Euclid Data Release (Q1), which represents a unique opportunity to study quasars (QSOs) in the Euclid Deep…

Testing Chemical Tagging with LAMOST: Intrinsic Abundance Dispersion of Subgiant Stars in the Galactic Disk

Wu Yaqian, Xiang Maosheng, Zhao Gang +4

The scatter in elemental abundances among stars of similar age and metallicity reflects chemical inhomogeneity in their birth environments, making abundance scatter a key observabl…

Euclid: Quick Data Release (Q1) -- Exploring the detailed visual morphology of galaxies in clusters

P. Mas-Buitrago, S. Kruk, D. O'Ryan +167

Galaxy clusters provide unique laboratories for studying environmental effects on galaxy evolution. The morphology--density (--) and morphology--cluster-centric radius (--…

Serendipitous discovery of an almost-dark galaxy in the Virgo Cluster

Minh Ngoc Le, Ignacio Trujillo, Sergio Guerra Arencibia +9

Analogues of extreme Local Group galaxies with very low surface brightnesses and large effective radii must exist elsewhere, still hidden due to current detection limits. We report…

ACES VII. Compact Continuum Source Catalog of the Central Molecular Zone

Jennifer Wallace, Cara Battersby, Nazar Budaiev +58

The Central Molecular Zone (CMZ) resides in the inner few hundred parsecs of our Galaxy, and despite being the largest reservoir of dense molecular gas in the Milky Way, it has a r…
