A $\wedge$-like metallicity profile in the disk of the Sagittarius dwarf galaxy
Unveiling the properties of the progenitors that formed the tidal structures of the Milky Way (MW) is essential for exploring the MW's assembly history.Cosmic-ray melt windows in interstellar ice make a four-carbon ketose but not the sugar pattern of G+0.693-0.027
Erythrulose (ERU), a four-carbon (C4) ketose, is reported towards the Galactic-centre cloud G+0.693-0.027 at a column density comparable to that of glycolaldehyde (GA), while the three-carbon (C3)…Probing the Optical/UV Continuum Variability of Active Galactic Nuclei with the Damped Random Walk Model
Optical/UV continuum variability over baselines of up to 20 yr is investigated using the damped random walk (DRW) model for 1214 active galactic nuclei (AGNs) compiled from Y. Shen et al. and C. J…The chemical evolution of the LMC from APOGEE abundances: a hybrid two-infall OMEGA+ analysis
The Large Magellanic Cloud (LMC) provides resolved stellar abundances and star-formation histories that can be used together to test models of dwarf-galaxy chemical evolution.Single-Parameter Exponential Model Outperforms Standard Dark Matter and Modified Newtonian Frameworks in Predicting Galactic Rotation Curves
The functional forms of galactic rotation curves provide a fundamental test for models of gravity and dark matter.Constraining Solid HNCO and Its Environment in Open JWST Data with Laboratory Spectra
The presence of HNCO in the gaseous phase is well known for the interstellar medium, but the molecule is not detected yet in the solid phase.VVV CL001: A strong candidate for the most ancient star cluster in the Galaxy
Finding the oldest globular cluster of the Galaxy is important to constrain a lower limit on the age of the Galaxy and the Universe.Understanding the formation of alpha-Fe bimodality in the Milky Way using constrained cosmological simulations of the Local Group
We use a novel suite of constrained cosmological simulations of the Local Group to investigate the formation of alpha--Fe bimodalities in stellar discs of Milky Way analogues.Phakoseismology: Asteroseismology of gravitationally microlensed stars
Asteroseismology relies on disk-integrated photometry or radial velocities, in which geometric cancellation suppresses modes of high spherical degree ($l\geq4$).Kinematically isolating intracluster light in AS1063: a distinct stellar population tracing the dark matter core
We present a technique using integral-field spectroscopy to kinematically isolate intracluster light (ICL) from the brightest cluster galaxy (BCG), enabling insights into their contrasting stellar…Pulsar J1909+0749 and Supernova Remnant G42.1-0.2: A case of a pulsar that has exited the shell of its associated supernova remnant
(Abridged) The ATNF pulsar catalogue features only 63 pulsars that are possibly associated with a supernova remnant (SNR).Coevolution of Dust Growth and Gravitational Instability in Massive Protostellar Disks
Massive protostellar disks are expected to sustain high accretion rates through gravitational instability, while dust growth may modify their opacity, cooling efficiency, and stability.KMOS Spectroscopic Follow-up of 16 Star Cluster Candidates of the Sagittarius Dwarf Galaxy
The Sagittarius (Sgr) dwarf spheroidal galaxy hosts several known globular clusters and numerous additional cluster candidates identified toward its crowded central regions.The clumpy fraction of galaxies at $z=1-9$ with JADES: evidence for a mass-dependent transition in clump origin
We measure the fraction of clumpy galaxies ($f_{\rm clumpy}$) over the redshift range $z=1-9$ and stellar masses $\log_{10}(M_\star/{\rm M_\odot}) \geq 8$ using JWST/NIRCam imaging from JADES.Large fluctuations and cusp-core transformation in dwarf galaxies
Dwarf galaxies are abundant and dark matter dominated, rendering them particularly relevant for testing a cosmological model dominated by a dark sector.Resolving the extended interstellar medium of infrared galaxies II. Fine-structure line emission
We investigate how star formation and active galactic nuclei (AGNs) shape the ionized and neutral interstellar medium in 67 nearby luminous and ultraluminous infrared galaxies from the Great…Resolving the extended interstellar medium of infrared galaxies I. Polycyclic aromatic hydrocarbon emission
We investigate spatial variations in polycyclic aromatic hydrocarbon (PAH) properties and photoelectric heating efficiency in 67 nearby luminous infrared galaxies from the Great Observatories…Chemical abundance patterns at z=1-7: Carbon, Nitrogen, Neon, Sulphur, and Argon abundances from JWST spectroscopy
The relative abundances of chemical elements in the interstellar medium (ISM) trace the history of star formation and chemical enrichment in galaxies.The Balmer Absorber Strength Problem of Little Red Dots
Little Red Dots (LRDs) commonly show Balmer absorption features.Arepo-CD: Coupling Collisional $N$-Body Dynamics with Moving-Mesh Magnetohydrodynamics
Star formation is a hierarchical, clustered process in turbulent giant molecular clouds (GMCs), where close stellar encounters can strongly affect cluster evolution and feedback.
