A New Catalog of Globular Clusters in the Milky Way
read the original abstract
A new revision of the McMaster catalog of Milky Way globular clusters is available. This is the first update since 2003 and the biggest single revision since the original version of the catalog published in 1996. The list now contains a total of 157 objects classified as globular clusters. Major upgrades have been made especially to the cluster coordinates, metallicities, and structural profile parameters, and the list of parameters now also includes central velocity dispersion. NB: This paper is a stand-alone publication available only on the astro-ph archive; it will not be published separately in a journal.

Lyman-alpha Pressure Strongly Enhances Pre-Supernova Feedback at Cosmic Dawn: The First Multi-Dimensional Lyman-alpha Radiation Hydrodynamics Simulations
First 2D Lyα RHD simulations show Lyman-alpha radiation pressure yields radiative forces of 2-16 times L_bol/c and force multipliers of 10-60, dominating other pre-supernova feedback in metal-poor environments.

Introducing AuriGLOBES: the effect of compressive tides, compact object-induced mass loss, and size evolution on modelling globular clusters
AuriGLOBES is a new subgrid model implemented in Auriga simulations that incorporates compressive tides and compact-object mass loss to transform an initial Schechter mass function into observed globular cluster popul...

The Hubble Missing Globular Clusters Survey IV. Ultra-faint compact satellites of the Milky Way. The case of Koposov 2
Koposov 2 is shown to be an old (13.7 Gyr) star cluster with half-light radius 2.7 pc, absolute magnitude -0.95, and stellar mass 372 solar masses, supporting a star cluster classification over a dwarf galaxy.

Bar-induced migration of $\omega$ Centauri away from Gaia Sausage-Enceladus
Bar-induced migration can move ω Cen from the GSE phase-space region, but requires Ω_b ≲ 26 km s^{-1} kpc^{-1}, challenging consensus on the bar speed.

Repopulating the pair-instability mass gap without sustained growth to massive IMBHs: the case of 47\,Tuc
Simulations of 47 Tuc show hierarchical mergers and occasional surviving primordial seeds above the pair-instability gap produce retained black holes of 45-1100 solar masses with distinct spin distributions, favoring ...

Formation of Parallel Stellar Streams through Encounters with Dark Matter Subhalos and Intermediate-Mass Black Holes
Encounters with dark perturbers split stellar streams into parallel structures, extending gap-like signatures to perpendicular density depletions as shown by analytical models and N-body simulations.

The one and the only: the pulsar - white dwarf system in NGC 6749
A phase-coherent 20-year timing solution for PSR J1905+0154A yields precise spin, orbital and astrometric parameters, identifies a helium white dwarf companion of 0.17-0.19 solar masses, and indicates the system may b...

The one and the only: the pulsar - white dwarf system in NGC 6749
A 20-year timing solution for PSR J1905+0154A confirms a helium white dwarf companion of 0.17-0.19 solar masses with 0.4-0.7 Gyr cooling age, but the system's 4.5-sigma velocity excess suggests it may not be bound to ...

Filter Design for Estimating the Stellar Metallicity of Metal-poor Stars from Gaia XP Spectra
Optimized filters centered at 3920-3960 Angstrom yield metallicity estimates with 0.18-0.39 dex precision down to [Fe/H] ~ -4 for metal-poor stars from Gaia XP spectra, enabling a catalog of 14.5 million such stars.

Bayesian Analysis of Gravitational Wave Microlensing Effects from Galactic Double White Dwarfs
Bayesian analysis of simulated Taiji observations shows microlensing from lenses above 10^5 solar masses can be distinguished from unlensed DWD signals when separation is below 3 Einstein radii, while lower masses or ...

Indicatives of Early Stages of Star Formation in the Universe
Metallicity peaks in globular clusters and circumgalactic clouds match across cosmic time and are reproduced by forming 3 million solar mass clusters during four enrichment stages of 10^8 solar mass clouds.
