Galaxies as stochastic systems: why the next breakthrough in galaxy evolution requires one hundred million spectra
Sandro Tacchella, Vasily Belokurov, Harry T. J. Bevins +4
Each galaxy is observed only once along its life, making galaxy evolution fundamentally an inverse statistical problem: time-dependent physics must be inferred from ensembles of si…
Orbital migration and heating history of the Galactic disc: a transition between the bimodal discs
HanYuan Zhang, Vasily Belokurov, Jason L. Sanders +7
Stellar orbits in the Galactic disc evolve from their birth to the current shape through both radial migration and dynamical heating. The history of their secular evolution is impr…
Enhanced rates of stellar radial migration in gas-rich discs at high redshift
HanYuan Zhang, Thor Tepper-García, Vasily Belokurov +6
Radial migration and dynamical heating redistribute stars within galactic discs and thereby modify the chemo-kinematic structure of their host galaxies. Usually, these secular proc…
STRRINGS: STReams in Residual Images of Nearby GalaxieS
E. Sola, D. Chemaly, V. Belokurov +11
Tidal features from galaxy mergers, particularly stellar streams, offer valuable insights into galaxy assembly and dark matter halo properties. This paper aims to identify a large…
On the connection between nitrogen-enhanced field stars and the Galactic globular clusters
Sarah G. Kane, Vasily Belokurov, Stephanie Monty +6
As sites of some of the most efficient star formation in the Universe, globular clusters (GCs) have long been hypothesized to be the building blocks of young galaxies. Within the M…
JADES: the chemical enrichment pattern of distant galaxies -- enhancement, silicon depletion, and iron enhancement
Yuki Isobe, Roberto Maiolino, Xihan Ji +26
We present gas-phase abundances of carbon (C), -elements (O, Ne, Si, and Ar) and iron (Fe) obtained from stacked spectra of high- star-forming galaxies with the deep Near Inf…
Lord of LRDs: Insights into a "Little Red Dot" with a low-ionization spectrum at z = 0.1
Xihan Ji, Francesco D'Eugenio, Ignas Juodžbalis +14
Recent observations by the James Webb Space Telescope (JWST) have revealed a puzzling population of optically red and compact galaxies with peculiar "V"-shaped spectra at high reds…
The THESAN-ZOOM project: Mystery N/O more -- uncovering the origin of peculiar chemical abundances and a not-so-fundamental metallicity relation at
William McClymont, Sandro Tacchella, Aaron Smith +15
We present an analysis of metallicities and chemical abundances at in the THESAN-ZOOM simulations. We find that smoothly curved gas-phase and stellar mass-metallicity rela…
Fewer Companions in the Crowd: The Low Close Binary Fraction in Globular Clusters from Gaia RVS
Dolev Bashi, Vasily Belokurov
In dense environments like globular clusters (GCs), dynamical interactions can disrupt or harden close binaries, nonetheless, detailed comparisons with field binary fractions remai…
The completeness of the open cluster census towards the Galactic anticentre
Emily L. Hunt, Tristan Cantat-Gaudin, Friedrich Anders +9
Open clusters have long been used as tracers of Galactic structure. However, without a selection function to describe the completeness of the cluster census, it is difficult to qua…
Connecting JWST discovered N/O-enhanced galaxies to globular clusters: Evidence from chemical imprints
Xihan Ji, Vasily Belokurov, Roberto Maiolino +5
Recent JWST observations have revealed a growing population of galaxies at with elevated nitrogen-to-oxygen ratios. These "N/O-enhanced" galaxies (NOEGs) exhibit near- to sup…
Observational Constraints of Radial Migration in the Galactic Disc Driven by the Slowing Bar
HanYuan Zhang, Vasily Belokurov, N. Wyn Evans +7
Radial migration is an important dynamical effect that has reshaped the Galactic disc, but its origin has yet to be elucidated. In this work, we present evidence that resonant drag…
Revealing the ages of metal-rich RR Lyrae via kinematic label transfer
HanYuan Zhang, Giuliano Iorio, Vasily Belokurov +3
RR Lyrae stars have long been considered reliable tracers of old, metal-poor populations, primarily due to their prevalence in globular clusters and the Galactic halo. However, the…
Low Surface Brightness structures from annotated deep CFHT images: effects of the host galaxy's properties and environment
Elisabeth Sola, Pierre-Alain Duc, Mathias Urbano +20
Hierarchical galactic evolution models predict that mergers drive galaxy growth, producing low surface brightness (LSB) tidal features that trace galaxies' late assembly. These fai…
Dynamical streams in the local stellar halo
Adam M. Dillamore, Jason L. Sanders, Vasily Belokurov +1
Co-moving groups of stars (streams) are well known in the velocity space of the disc near the Sun. Many are thought to arise from resonances with the Galactic bar or spiral arms. I…
VIRAC2: NIR Astrometry and Time Series Photometry for 500M+ Stars from the VVV and VVVX Surveys
Leigh C. Smith, Philip W. Lucas, Sergey E. Koposov +11
We present VIRAC2, a catalogue of positions, proper motions, parallaxes and , , , , and near-infrared photometric time series of 545 346 537 unique stars. The cat…
