LYRA: The formation and growth of nuclear star clusters in dwarf galaxies

Joaquin Sureda, Azadeh Fattahi, Sownak Bose +5

Nuclear star clusters (NSCs) are dense massive star clusters ubiquitous in galactic centres across various mass regimes, present in up to per cent of dwarf galaxies with $…

A shot in the dark: searching for dark substructures in the RX J0437+00 galaxy cluster

David J. Lagattuta, Mathilde Jauzac, Jessica E. Doppel +2

Obtaining a census of dark matter structures at low mass () can provide strong constraints on the nature of dark matter, though identifying such structures remai…

LYRA ultra-faints: The emergence of faint dwarf galaxies in the presence of an early Lyman-Werner background

Shaun T. Brown, Azadeh Fattahi, Thales A. Gutcke +6

We present a suite of zoom-in cosmological hydrodynamical simulations of dwarf galaxies using the LYRA galaxy formation model with an extremely high mass resolution of $4\, \mathrm…

Tiny galaxies and dark substructures: exploring the "dark" subhaloes in TNG50

Jessica E. Doppel, Mathilde Jauzac, David J. Lagattuta +2

Dark matter haloes and subhaloes that host no luminous counterpart are predicted within our current understanding of galaxy formation within a CDM paradigm. Observational tests,…

Strong LensIng and Cluster Evolution (SLICE) with JWST: Early Results, Lens Models, and High-Redshift Detections

Catherine Cerny, Guillaume Mahler, Keren Sharon +24

We leverage JWST's superb resolution to derive strong lensing mass maps of 14 clusters, spanning a redshift range of and a mass range of $M_{500}\sim2-12 \times…

Imposters among us: globular cluster kinematics and the halo mass of ultra-diffuse galaxies in clusters

Jessica E. Doppel, Laura V. Sales, José A. Benavides +4

The velocity dispersion of globular clusters (GCs) around ultra-diffuse galaxies (UDGs) in the Virgo cluster spans a wide range, including cases where GC kinematics suggest halos a…

The progenitors of the intra-cluster light and intra-cluster globular clusters in galaxy groups and clusters

Niusha Ahvazi, Laura V. Sales, Jessica E. Doppel +3

We use the IllustrisTNG50 cosmological hydrodynamical simulation, complemented by a catalog of tagged globular clusters, to investigate the properties and build up of two extended…

Modeling globular clusters in the TNG50 simulation: predictions from dwarfs to giants

Jessica E. Doppel, Laura V. Sales, Dylan Nelson +9

We present a post-processing catalog of globular clusters (GCs) for the most massive groups and clusters in the TNG50 simulation of the IlllustrisTNG project (virial masses $M…

Globular clusters as tracers of the dark matter content of dwarfs in galaxy clusters

Jessica E. Doppel, Laura V. Sales, Julio F. Navarro +3

Globular clusters (GCs) are often used to estimate the dark matter content of galaxies, especially dwarfs, where other kinematic tracers are lacking. These estimates typically assu…

Simulating the Spatial Distribution and Kinematics of Globular Clusters within Galaxy Clusters in Illustris

Felipe Ramos-Almendares, Laura V. Sales, Mario G. Abadi +3

We study the assembly of globular clusters (GCs) in 9 galaxy clusters using the cosmological simulation Illustris. GCs are tagged to individual galaxies at their infall time. The t…
